you said, " like the rake on a motorcycle", NOW THAT makes sense!!!! Thank you.

This is the first correct death wobble video I’ve ever watched on the Internet good job buddy

One of the simplest and best explanations I've seen. Thank you!

What a great job at explaining in detail the causes of death wobble! Now I have a good idea of what to look for in my components etc. Thanks!

Excellent video! I have always felt that death wobble was a sign of problems. My 2021 JLU Rubicon, has non-stock axles and a 2 1/2 inch lift running 39 inch tires with beadlock wheels. At 65 mph there was a very slight wobble. After watching your video, I decided to check the balance of my beadlock wheels. I used balancing beads when I installed the tires on the wheels. So..., I pulled the ring off both wheels and vacuumed out the beads and took them to a local tire shop to have them both balanced. Wow, problem solved. It now drives like a dream.

Got my rotors replaced and brake pads done, shock absorbers replaced, 4 all new tires, steering damper replaced ...This by far got to be the solution to my death wobble crisis on my 04 Jeep TJ...

Excellent vid, thank you. I’m tired of hearing the bandaid solutions. I knew control arms were a good starting place but now glad to know that the drive shaft is related

One of my Jeep groups suggested your videos. I’m on my 3rd Jeep. My 2018JL hasn’t had death wobble “yet”, but my steering is all over the place. It has a 2.5” left prior to my buying it. Thank you for the explanation, I plan to order what I need now to fix this!!

Great video. First guy I have seen that talks about the relationship between caster and drive shaft angle. I will add two more easy things to look at. Front alignment toe. A slight amount of toe in, still within specs will help. Do not have any toe out. Also check tire pressure. To much pressure can make it worse. Most Jeeps like between 28-35 psi. Generally the lower the better.

top notch bro! Well explained and perfectly illustrated

I can't believe what I have just seen !! This man is the only man that has shown the actual real reason for the wobble ! The shopping trolley wheel shacking is what made me relies my problem was me changing the caster angle with the 2.50 lift. My 2000xj has factory adjustment ,the hole where the lower control arm attaches to the body bracket is slotted and there's an adjuster is also there that alowes the arm to be moved either direction . So I put the steering back to factory specs and walla !! steers like a new xj jeep !

When I bought my stock jeep, it already had the death wobble that I didn't know about initially. I installed a 'levelling' kit, which is only like 2 inches front, 1.5 in the back, and still had the wobble. I noticed the steering stabilizer had leak marks on it, so I changed it, and that 'fixed' the wobble, and I thought that was that. About 18 months later, it was back, so I changed the stabilizer again, once again 'fixing' the wobble. So this month it was back, and I bought an upgraded steering stabilizer, but before installing it, I decided to, once again, dig into researching the problem to try and see WHY a vehicle designed to take bumps apparently couldn't take even a slight bump on the highway. So I settled on the lower control arms after watching your vid, and bought adjustable ones, and simply eye-balled the length by laying it next to a stock one I just removed from the jeep, adding about quarter to half an inch to the length, and then matching the second new adjustable control arm to the first to get equal lengths, and thereafter installing both new ones on the jeep one at a time. I had no idea how much longer to set the new control arms, and they're somewhere between 1/4 inch to 1/2 inch longer than stock. I took the jeep for a drive and immediately it feels 'stiffer, and the straightening out of turns feel faster, too. It felt a lot 'looser' before. I've yet to take it on my daily route and see if the wobble is gone or not, but it seems a small lengthening made a huge difference already. So does that sound right? Will such a small control arm extension be enough to fix the caster and thus the wobble? Are the tolerances really that close? Also, I haven't tightened the locking nut on the new control arms yet. Does it really matter?

Hey Doc your the first person who has explained properly and not just gone straight to the track bar. I only did a 2" lift amd level but I've been fighting death wobble off and on ever since. I do have to replace my front upper control arm bushings and im hoping that helps but how do I measure my caster cause nobody has ever pointed that out for me. Awesome vid man!

Awesome educational video boss! We need more people like you in th world

Whaaaaat a great steering geometry explanation! Thaks!

Great stuff on this topic. Thank you.

Hi. Very great explanation, and I especially like the shopping cart example that we can all relate. When adjusting the position of the axle (resetting the wheelbase) and the caster after installing adjustable long arms on my XJ, should the Jeep be off the ground, off its own weight?

the only guy on line that knows the deal

Great explanation thanks a lot

Rotating my tires front to back worked for my shimmy on my 97 TJ, thanks.

Just happened to me this morning at 45mph. It changed the way I look at life. BTW the Doc attire forces me to believe everything you say.

I have a 93 Jeep Grand Cherokee Laredo ZJ and every time I hit a really bad bump going under 35 it makes the death wobble kick in until I slow down and can correct it long enough for me to get that going again like you said exactly how do I go about getting a longer control arm I'm not very mechanically inclined so how much would this cost to get fixed if I took it to a local shop

Can you fix caster angle without swapping the lower control arms? I plan to do it soon but just spent so much on the lift kit, tires, and steering components (tie rods, adjustable track bar, and steering damper)

Great video! It’s helping me understand why I have developed a death wobble. I experienced it twice for the first time tonight at 70mph. I just installed a 4.5 lift on my 86 MJ that came with fix lower control arms. No uppers. But I did install a new adjustable track bar. Do you think I’m going to have to replace both the upper and lower control arms with adjustable ones to fix my issue? Or can you think of another option? Thanks again for the great video.

See I have these symptoms especially in the 55-65 speed range. But mine doesnt seem to be triggered by bumps... it seems to be triggered by certain sections of roads. And to top it off it's usually the same section everytime like the road is really rough when in fact it's not. To top it off I've driven those sections in multiple vehicles without the same issue. I changed out my tie rod arm on the driver side as it was in rough shape. But hasn't seemed to really help the issue. I should not as well it's a 2w drive jk 07 wrangler

I have had everything done on my 2003 tj to try and fix my death wobble and the only thing that fixed it was to have adjustable castor bolts put on. Fixed! My jeep is all stock,no lifts

I have intermittent death wobble on a 13 jk no lift but running 35s with aftermarket fender kit. Can’t find anything loose any ideas

Where is the best spot on the axle to measure the caster angel? 2016 Jeep JK rubicon. front dana 44,4 1/2 metal cloak lift kit .are you willing to give specs for the best length of the front upper and lower control to make the caster right on a 4 1/2 lift? just asking . I know all jeeps are a little different but not by much . Thanks

Would I only need the lower control arms or both upper and lower front and rear?

What if you haven't lifted at all, but went from stock baby tires to 32's, does this change that angle as well?

Your awesome great info

This is the best EXPLANATION of death wobble.....SOOO! couple years ago, I experienced DEATH WOBBLE, I then fell for the TERAFLEX HD BALL JOINTS. This APPEARED to work for a couple years. Did this really do anything? Just yesterday, It's back!... Thoughts Please.

If an elongated lower control arm helps, a shortened upper control arm should do the same ? I'm just asking because the longer lower control armm helped in my case but I wanted to keep the oem lowers because the adjustable lower had crappy bushings. so installed adjustable uppers (shortened as much as the lowers were longer) but it did not have the same positive effect like the longer lowers. Any suggestions where I'm thinking wrong ?

You really are Dr. Deathwobble! Thanks!

I got a 2014 Sahara stock and I'm getting a death wobble what you reckon it could be?

So if I’m understanding this correctly, my caster is one of the first things to check to resolving my death wobble. I should check that ahead of my Track Bar, Ball Joints, and Tie Rod Ends. I’m in a 14 JKU that I lifted 2.5” on 35s. Lifted is a couple years ago and just now running into consistent wobble problems.

Hi What about suzuki samurai that it has leaf springs for suspension and dosent have upper and lower control arm?

I just bought a 92 limited xj, its been fully restored, pretty much everything new. My problem is the steering is way to tight, it wont self steer back to center, and it wants to follow off camber parts in the road, but it has zero wobble, even over some of the worst bumps. It has a 3 inch lift. 31 inch tires, new ball joints, zj steering components, new steering box, new steering pump, new lines, and new steering shaft from column.

I have a 2018 JL. No issues with it until I brought it in for an oil change and a recall. There are no mods nor is it lifted. A week after I brought it in I experienced my first death wobble. Took it to the dealer and was told o needed a wheel alignment. Did that. That same week it happened again. Took it to the dealer. I was told the recall was done incorrectly and that they were going to re do the recall. A few days later the wobble happened again. Now it's at the dealer waiting to be serviced again. I hope the 4th time is a charm

REALLY Enjoy your presentations ! Great Explanations. My trouble is: after replacing Everything, and what I (THINK) is Corrected Caster, and Three alignments, I STILL have it ! 2WD XJ 3” ~ OE spec for Caster is 5.3 - 8.0° (so I’m told). Mine is at 8.3° ..... ? Shouldn’t that be GOOD ? I’m at my wits end, trying to eliminate DW 🤯😩

I installed a 2 inch Mopar lift, if I put the original suspension back on will this death wobble stop?

So you mostly talked about lifting and then seeing death wobble. I have a stock JL and it seems to trigger death wobble way too often. Cant imagine they built it with negative caster.. The only "recall" the dealer says was out there was the steering stabilizer which we all know is a band aid. So was the 18 JL just built wrong?

So I need to order an adjustable lower control arm, correct?

I have a 2003 Wrangler all stock. Can ball joints produce death wobble?

Thanks for this explanation! How do I assess what part (lower control arm?) I need to buy? Can I send you pictures of the jeep I am thinking about buying? Would you be able to identify the solution from photos? Can I pay you for this service? Thanks!

Will installing Control Arm Drop Bracket help with Death Wobble..?

Great video. Can you explain the difference between "caster" and "camber"? From the drawing it looks like the ball joint is out to the side, not forward like a chopper.

So I just put on new shocks yesterday not a lift because the old ones were completely shot. I hit a weird bump and I got the death wobble once. I’m thinking it’s the stabilizer because that stabilizer is probably bad too.

WHERE IS YOUR SHOP? Please put your contact info in the description. Of Every video. Would love to have you work on my Jeeps.

Question....what would be the proper Caster angle for a 2018 Jeep 4d Rubicon

could Front Brakes cause a wobbling or shaking effect in the front end of a 2007 Jeep Wrangler - no lift and standard size tires although meating tread - never had the problem and then it started - an auto repair shop says we need front brakes - didn't have the shake until after they evaluated the vehicle

Can someone confirm, all I need is the front lowers to correct the caster. I have ‘14 JK with Rough Country 3.5” liftkit. I dont want to get front uppers if I dont need it right now. Just want to stop the dealth wobble. Note: All my other steering components are new. I.e . Drag link , track bar etc

Can you recommend a Mechanic in Denver that can fix the Death Wobble?

I'm a Tech with a Stock 2018 Jeep JL 56k has Death Wobble, everything appears tight. looking for the solution here. most people talk about lifted jeeps but this is a Bone stock JL. im reading something about deflection in the aluminum Gear Box.

Were are you located ..

So if I added a 2.5 inch lift spring to the front of my zj would that be enough to throw off my caster. I’ve always heard that xjs/zjs didnt need longer control arms until 3.5 or more inches of lift. Mine goes into death wobble at any slight bump or variation in the road after 45 mph. If I stay at or below 45 I don’t have death wobble but I still have really bad bump steer

I have it bad s to ock 2014 Silverado but it's used for snow and off-roading it's crazy

i found my tracking bar rubber was worn on the frame end. with the jeep on the ground, not on a jack, turn the wheel left and right hard, that will force the tracking bar to move in its socket if it is worn, can't see it when on a jack, not enough resistance.

I have a 08 jk and was looking at how I can change the camber can’t find any shims or cam bolts that would bring the top of the tire in to change camber Only cam bolts to change drive line pinion angle And found shims but not sure how that changes camber angle in a solid front axle Unless there tapered thinner at the top than the bottom j

Dear Dr. Death Wobble, I’m having some death wobble problems after lifting my WJ, do you think that a 3” lift is enough to require adjustable lower arms and a caster correction? I’m showing around 5.5° of caster currently. Thanks!

Just got off the highway and experienced the death wobble at 70 mph in my 2018 JLU stock, had to slow to 15 mph before I got it under control. The dealer recalled and put in a new steering dampener 2 weeks ago and had no prob before that. Did not feel right since they replaced it. Ideas??? Thank God my kids were not driving is all I can say.

I just put a 2 1/2" lift on my 2012 jk rubi, death wobble started immediately after, also noticed the steering felt "light". First thing we did was check the track bar. I put on an adjustable one, no change. After seeing your video we put on adjustable lower control arms and adjusted them to what the lift called for which is 23 1/8" (stock 22 1/2")from center hole to center hole. Still death wobble. Just had an alignment done and this thing is worse. They pushed the lower control arm out to 24". The steering was tighter, but it shook at 15mph.... Is my happy spot between 23 1/8 and 24? Everything else is tight, ball joints, tie rods... Ect. HELP PLEASE, what am I missing?!

So pretty much just add a DUAL steering stabilizer and call it good ! Lol jk man! You described it very well!! Your name fits you well lol DR.

So does this mean the yj or before isn't susceptible to death wobble?

my 2017 jeep jk has death wobble, I changed my tie rod/drag link by teraflex. everything was good after hitting bumps/ or potholes no death wobble but somehow it came back lol I rotated my tires, balanced and wheel alignment. still have the problem. I got my control arm checked, ball joints checked and steering stabilizer checked. they were good but I'm guessing its my track bar cause when I turn the wheel left and right multiple times I hear knocking coming from the track bar its by steinjager but when I got it tightened this stupid death wobble keep happening. forgot to mention my car is lifted 2.5in help please I literally spent thousands of dollars but no luck

Won't that make the driveshaft bind ?

Will this work for Land Rover defender?

Hello, 2009 JKU, just replaced tie rods, drag link and track bar, all teraflex, no lift, and still have death wobble, I took it to an alignment shop and they told me the ball bearings are good, help!!! What else could it be?

How much does it cost to changes the track bars?

So I have a death wobble after I hit a bump but my suspension is stock what can I do to fix that

I have an 02 Wrangler with 66,000miles and factory suspension. I'm getting death wobble. Any suggestions?

My 07 jk unlimited is freaking crazy and it's stock started around 60k steering stabe work for 20k then start again I know have 150k its seriously crazy again...but stock 18inch tires 07 Sahara 4 door seriously frustrating

Does the 2” lift kit affect the same way as 3” lift or higher kit to the ball joints

Just wondering if the steering gear box would also a play a major roll in the death wobble?

Doing the permanent fix on my WJ with 4" lift. I want 7 degrees caster AND no vibes from my front driveshaft, rotating the C's on the axle now.

It is just rotational vibration which is matches the natural resonance; just need steering stabilizers for dampening and more conservative build and driving habits!

I have a 3.5" Metalcloak lift with 1.25 body lift (was on when I bought the Jeep used). I had death wobble the other day, it really happens when I hit something with the driver's side tire. I only have upper adjustable arms, the caster is 4.7 L 4.9R. Took it to the dealer and they said the brand new Metalcloak steering stabilizer was bad and needed a new one from Fox($350).

I had death wobble in my 2001 jeep xj 2x4 with large tires. Bought regular tires and wobble went away.

I had one do it after a tire rotate, bone stock. I balanced the tires and visually saw they were damn OK, noticed new ball joints and checked the links were all tight. That axle design is absolutely horrible!

no zjs

Just found this, I would love to pick your brain cos I've done all this but I still hav death wobbles

I experienced death wobble on an empty street in the suburbs. I would've cried for mommy had i been on the freeway. It was definitely a pucker feeling.

Hmm. Probably why my lifted shopping cart rides like shit. Jokes aside, thanks for the info!

I'm sure your diagram made sense to you but I have no idea what that was supposed to represent and I know what caster/camber, etc. is. Maybe take 15 seconds at the beginning to describe your doodle

Suggest you look at how the Caster works. Feel what you are saying might be misleading. Just saying.

I get death wobble on my walmart shopping carts

Geometry Brackets are your friend.

2WD Wrangler had death wobble, balenced and rotated tires and wear is ok, new ball joints, tie rod ends and alignment. It seemed resolved, But wait........NO it isnt! Customer wanted a 3" spring lift to level the jeep out and add tire clearance, checked pinion angle/caster and it was at + 7 deg. reset to +4.5 and still have death wobble. Trailing arms have good bushings..

I think my jeep is doing the death wobble

The root of death wobble is improper toe. Any amount of toe in can cause it. Or if you experiment too far out can cause it also. With larger footprint tires, you'll usually end up slightly out before it goes away. It really is that simple.

Wrong. Lifting a Jeep adds caster, it doesn't reduce caster(upper control arm is shorter than the lower control arm). Lifting the Jeep caster increases. I have 43 years in front end alignment. First death wobble fix I had was a Freightliner tractor that the factory put too much caster in the straight axle. Dropped the caster 3 degrees, problem solved.

Damn I thought it was Tyson Fury 🤭🤭😬

MY DAUGHTER BOUGHT A NEW JEEP WRANGLER AND IS GETTING THE DEATH WOBBLE , SO SAD SHOULD OF GOT A TOYOTA !!!

You can't fix it wobbling is a infinite and you will die at 0 if you get grabbed

Sorry to say but this video explanation of a technical issue concerning the geometry and dynamic stability of a vehicle is as far from the truth is his going to get!!
