Check the Viscous Damper on the engine, a bad damper will mostly be felt at higher speeds and will be felt in the transmission and drive-train components.

I have a 2017 ram 2500, 26k miles that had exactly the same issue with a subtle shaking starting at ~65mph. Mind you, the truck was totaled, I got it from an auction and repaired it. It had slight shaking exactly as your showing and describing. I was reading over these comments and was very worried. Replaced the sway bar links, started looking on Amazon for a steering box stabilizer brace. But tried one more quick thing, and it WORKED (maybe I just got lucky). I took it to discount tire and had all the wheel ROAD FORCE BALANCED, I sat there abs watched them do it. The first tech had no clue how to use the machine right, he was just gonna do a regular balance, but I started probing him about how I was expecting the force roller to come into contact with the wheel for this balance. He called a manager that actually DID know how to use it, they had to remount the tires onto the rims so a certain portion of the tire aligned with the valve stem. It ACTUALLY WORKED, driving home so glad I thought this was gonna be a nightmare, been trying to figure out the shaking several days. My conclusion is, if you’re going to balance the wheels on your truck, WATCH them do it, good chance that they will do a regular balance on your wheels and it may or may not actually fix the issue like it did for me.

I own a 2018 Ram 2500 CTD. I had a smooth running truck with the Firestone Tires and 18" OEM Allow wheels from the day I drove it off the lot. The first tire rotation caused my truck to start vibrating same as yours. Ended up one of the front tires were worn just enough to make the bed shake once they were mounted on the rear axle. I could move them back to the front and it drove smooth again. The front is over 5K lbs. dead weight whereas the rear is about 3K lbs. For some reason the rear of the truck does not like untrue or out of round tires. You may want to try this. Put your rear axle up on jack stands, turn off the traction control, start the engine, put it in gear and run up to 70mph. I bet you'll find the bed shaking like crazy. That would mean either your wheel/tire combo is bad or the axle bolt circle is out of round making the tire run off center. I recently installed a new set of Michelin Defender tires on my OEM wheels. Some tires took 6 oz. of weight to balance. The Firestone tires had only 1 or 2 oz of weight on each one. The truck runs smooth at any speed now. In short, your truck has a problem in the rear. Either the OEM tires/wheels are out of round, the axle bolt circle is of center, or even you have a bad axle hub or bearing. Try putting the truck on jack stands. You will find your problem quickly.

My 14 did it. Ended up taking the driveshaft to a performance shop, had it spun and it was actually out of round. No balancing would help. Ended up getting a new 5” Alcoa driveshaft made and it was smooth as butter!

Thanks for posting this. I have a 10 dakota and having same rear end shakes. I was considering upgrading to a full size ram but now I think I'll pass. I do not want to go through this again!

Just finished the lemon law process with my 17 3500 dually. Went through 4 sets of tires and the dealers kept saying it was the tires. Bought the truck brand new 5 miles on it, started having the "shakes" at around 3,000 miles 65-78mph . Dealers (went to multiple) kept saying tires/rim/balance/alignment (all not covered under warranty). The last service was centramatic wheel balancers, new tires AND rims now its 72-77mph. I started the lemon process at 35k miles, over 2 years ago and because of it being my daily driver and COVID really "messed" the case up because attorney fees kept racking up and the courts were closed all last year. Was at 80k miles by the time I had a court date and ended up settling out of court because of the miles on the truck. My advice is if you plan on doing the lemon law don't drive the truck if you can avoid it which I couldn't justify having an $70,000 paper weight. Hopefully with money I get, I can dabble in trying to find a fix for it. Also I never thought I would sue a company but with so many people having that issue and paying that much for a vehicle. They need to know it's an issue and that's the way to get their attention for sure.

2018 Ram Power Wagon, had the shakes since the first drive home. I've replace tires, multiple road force balances and regular balances, bought centramatic balancers, no fix at all. 70-85 MPH.

My 2014 f250 did that for the first 12k miles at the same speed. The dealer changed out both drive shafts and tires twice and nothing fixed it. They also road force balanced the tires more times than I could count. While towing our camper, I noticed the stock Ranchos were getting weak so I replace them with Bilsteins and have had no shake since 12k miles. I now have 104k miles and smooth sailing. I think the Ram 3500 and Ford f250 and f350s have a very similar suspensions and drivetrains.

I had the same issue with my 2020. It started doing it around 6,000 miles. ended up pulling the rear axles and they were both bent, and twisted 5/16 of a inch. It solved the issue for around 30,000 miles, and it is starting again.

Also you could buy centramatic balancers for the wheels. I had those same Coopers and almost bought them and Tire D finally got them worked out and then I got a 2020. If I go w Coopers on my 2029, I’m going to start out w these balancers.

Very strange. I bought my 2018 Dually used with 12000 on the odometer. The stock Nexen tires were garbage, they would develop flat spots if parked for a week or so. I replaced the tires with a set of General Grabber ATs. No more issues and it’s by far the nicest truck I’ve ever bought. That being said, the Coopers should have cured your truck just the same. That’s not a front end issue you have, it’s rotational out of balance. Maybe an axel shaft or something not true or out of round. Not a wobble, it’s a bounce and yes tires are number 1 suspect always. I would doubt serious enough to warrant giving you anew truck over but all the same they need to fix it. Hope you get it sorted out fella.

I have the exact same issue with my 2017 3500. Dealership says its my tires. They are brand new BFG's with 200 miles on them that were road force balanced. I'm considering pursuing the lemon law...what did FCA do for you? Did they buy back your truck?

I have 2020, 2021, and 2022 rams 3500s. Tradesman 20 , big horn 21 , Laramie 22 all shakes at 65 mph to 90 . New tires . Balance done

On our 2016 we started feeling the vibration in first 5000 miles. Now at 75K, among three different dealers, we have a new drive shaft and new half shaft on passenger side on rear end after uncovering a slight bend to it but the vibration is still there. Changing to third set of tires soon. Firestone Transforce ATs were OEM, changed out at about 40k to BFG KO2s that are all chopped now. Bought Cooper AT3 XLTs from TireRack and will have dealership do the mount and balance. We also have Centramatic balancers, which have helped but the vibration is still there. The hunt continues... We hate to have to do the lemon law thing because we don't believe it's there to help the consumer but we may have to try...

That's what sucks about the lemon laws. There's a wide ongoing misconception that lemon laws are there to protect the customer. Lemon laws are put in place to protect the dealer from being held responsible for manufacturer defects.

04 3500. Noticed the same problem here the other day. Trying to find out what it can be. Have a reinforced re48 with a tripple disk converter. At first i tought it could be the converter but reading the comment i belive one of those mondaycars found its way to norway, shake happens at around 60 to 70 miles

Same problem with a 2017 CC DRW 4WD with Aisin. Truck has been in 4 different shops for greater than 3 months. First they agree with the problem and then they back out and say it's normal! 3rd set of tires 2 alignments and now out of warranty. I believe I discovered the recall when I found my pitman arm nut and track bar loosened to the point of near catastrophe. Ram Customer Care tries to help but is shut down by corporate so it seems. This is my 3rd new from dealership Dodge diesel truck in 11 years. It is also my last! I love my truck but if dodge refuses to stand behind their product, why should I? Here I come GM!

2017 Laramie Longhorns cummins with aisin. Shakes. New general at2. Still shakes.

I have an 07 dually and it shakes at 65mph and 70mph but if I punch it up to 80mph shaking goes away. Its the rear. I originally thought it wanted som weight but not sure.

Mine is an 07 mega I bought in 2016. 3 sets of tires, 2 sets of rims. Centramics. I'm fairly certain my issue is the rear 2 piece driveshaft. Putting a camera underneath today. 2018s have a one piece. I wonder why the change...

Hi Cody I live in NM as well. Did you continue to go through with the lemon law process?

I have the same problem with mine. 2020 3500 cummins. I have already changed 2 sets of tires and 1 set rims and the problem continues at every speed after 30mph

Try your drive shafts brother. Good luck man.

Have you tried putting it in park and slowly raising the rpm to 2000. Looked like your shaking is around 1400 rpm i had same kinda thing and also noticed that it’s vibrating in park at same rpm on my 2014 2500.

I have the same problem now on a 2017 2500.. road forced/new tires everything.. love the truck but cannot stand the shake at high speed

Did they get this solved? I have 15 mega cab that has the same issue.

My truck vibrates at turning directions ( at any speed 0-45 / 45 -65 etc… but , my axle does like a skiping jumps as driving

People get confused shaking isone thing and vibration is other thing and what you have is vibration,,,check your drive shaft

I have a 2003 2500 and it's starting the shakes around 70mph do you know what was causing the problem?

my shake is back I don't have the aisin trans. my shake isn't constant. but same shake as yours.

I have the same problem on my 2500 did you ever find out what it was?

Did u check the axles the suspension wheel bearings. Go to a garage mecanic and not a dealer

If they would just put the Cummins and Allison trans in a Ford I would buy it in a heartbeat

I've got the same problem. going through hell right now with the dealership

good luck. took me 5 years to get my lemon law taken care of. FCA is terrible.

Common on mega cabs , longer driveshaft

I have a 2014 Ram 1500 4x4 Outdoorsman and mine does this at about 62 or 63 mph and it stops at 70 mph I hate it but I love my truck is the axle warped in back or the something

My 2018 2500 Cummins does the same damn thing. Multiple visits to dealer no fix in sight.

My 2013 Ram 3500 SRW has this problem also.

2008 RAM 1500 with 139k. Does the same thing only starts at 50 mph. I bought the truck used and thought it just needed tires. Replaced tires, motor mounts, shocks, U-joints, balanced driveshaft, tires rebalanced and even tried Equal. Still shakes. If you get anywhere I'd love to hear.

Mine was hell... 2019 2500 diesel It was bad front drive shaft made ball joints bad. Made wheels bad.. Change wheels. It was good. Wobble came back. Changed bank joints and new tires wobble came back. Changed front drive shaft and tires again..

Some guy was saying body mounts can be the problem

My 2021 ram 2500 shakes as well. 3 sets of tires in 2 months.

Did yours vibrate consistently at 70mph or would it intermittently come and go at 70mph? Sorry you had to go through this with a $70k dollar brand new truck. That’s ridiculous Ram.

My 2018 does the EXACT same thing except I bought it used and it didn’t do it then…3 months ago.

I have the exact. same. problem. at the exact. same. speed. Three sets of tires (on FCA's dime), multiple road force balances, etc. etc. Mine is a CCLB 3500 SRW. I went through the lemon law (in NJ) and ended up with a measly settlement from FCA that would probably cover another set of tires. This was the absolute most frustrating thing I have EVER gone through ESPECIALLY after forking out $65 large for a premium truck. Long story short I have a beautiful 2016 Laramie with 12,000 miles on it sitting in my driveway because I can't stand to drive it. Shame on FCA's part for hanging their customers out to dry! Let me know if it was ever solved

I have the same problem going though hell in the 2 year's I've had my truck it's been in the shop 60 day's in total we have a complaint filed . So I asked my mechanic he said carrier bearing is the problem go get a one peice driveline problem will be soveled he has seen others but we want dodge to honor any warranty due to the truck only having 32000 on it .

Thank you

AND also dont leave the dealer lot with firestone tires -just saying

I found my shake a couple of days ago. Drw. Put the rearend in the air and have someone put it in gear. Now watch your wheels and calipers move around. The hubs and axles are apparently the issue. I haven't had a chance to open it up to find the exact problem but really soon, or I'll graft in a rearend from a GM or ford.

I ok have a 2016 3500 and the same thing for me replaced everything but still shakes

Well, I picked up a new to me 2016 2500 and have the exact same issue. I got new wheels/tires and have the same issue. Did you ever get your issue resolved or trade it?

Hey buddy did you fixed the problem? I have the same issue on my 2013 ram 1500 sport and nobody can't figure out what it is.

I have a ram 2017 3500 dually and mine does the same exact thing. sometimes it will go away depending on the road surface. let me know what you find out! My truck is also totally stock.

What about driveshaft balance?

Did you ever find out why it shakes my RAM 1500 is doing the same thing

Check U joints and drive shaft

Wondering if you fixed it, because my 1500 did it and it was the Inner CV Joint Passengers Side

Steering gearbox stabilizer brace on amazon. Worth the money.

My new 2018 ram cummins g56 manual longbed with firestones does the same thing from day one. 67 to 80 mph. Now at 4200 miles and 5 visits to the shop and a new driveshaft with trans mount it still does the same thing. They now tell me its normal. It wasnt normal when they tried to fix it and now its normal after then cant fix it.

Looks like it needs a body jossel an needs the bounce weight on the rear hitch like a ford

what was the final outcome of this? I have an 2018 Ram 2500 and going through same issues.

Try a set of Michelin ATX's. Michelin tires a a tighter "round" spec.

Motor mounts it could be.

Looks like Abq. I have an 18 with the same issues. Did you resolve the issue? What was it?

I have the same exact problem changed tires two alignments they just changed my rear drive shaft they have my truck now and trying to figure it out I am pissed we will see what happens I have a 2016 ram 3500 dully it’s been shaking from day 1

my 2014 ram 3500 dually two wheel drive has 11700 miles and its starting to vib at 70 mph :(

I have the same issue in my 2017 2500. After 4 times to 2 different dealers this last dealer just told me that there is nothing they can do for it. They said its a problem on 2017 to 2019 and there is no solution. Were you able to get yours fixed?

do you think it might be because of the locked hubs which make your truck always in 4x4?

I have a 2018 Ram 2500 mega cab Longhorn with 5k mikes that does the same exact thing as you describe here. On second set of tires. About to start the dispute process. the problem is in the SIZE of the tires. Ram is the only truck to use 285/60-20. GM and Ford use 275/65-20.

Continuing to do the same thing expecting a different result is the definition of insanity! After first set of new tires didn’t fix it time to look at suspension and drive line . A drive shaft that lost a balance weight will do this.

Get your tires trued. Its not a truck problem its a tire problem, the ram is veryyyyyyy sensitive to tires that are out of round. Most large tires are not built perfect. I had my first 3500 replaced by dodge, tires, wheels, driveshafts 7 times at the dealer in a month, they replaced my truck with another 3500, didnt shake as bad. I now had my truck 3 years 60k miles. Just bought brand new tires at 60k, balance and alighnment, truck shook worse than ever, you dont need road force. I took my truck to a semi shop, with the new tires, they trued the tires, cut the tread on axle. Its smoother than a damn cadillac now.

Its the driveshaft

I have the same problem on my 2013 ram 2500 4x4 65-70 it's terrible rear end shake. I can look out of my side mirror and see my back wheel wobbling. Tires and rims are good. I have no idea what's happening man but it's annoying. I've heard it's the driveshaft or mounts or you'll have to replace the entire rear end.

just got my 2018 back from dealer I had the same problem after 4 trips they replaced the driveshaft seems to be ok now

Lost my arbitration case. Ram said it is normal and it gets me from point a to point b. Just sick from not wanting to drive the vibrator

Recommend you try balancing sand on the tires. It works for me steady as a rock below 70 and above 70, it takes about 2 minutes to dial it in. I have the same Coopers.

Been shaking for three years now

I'm having same issue on Ram 1500 hemi only 70k mile

My theory is that it’s the carrier bearing in the 2 piece driveshafts.

owned 5,never had a shake

What was the outcome from this?

Any fix? Did you go for lemon

Same here it’s so annoying

16 ram 3500 limited does the same thing

Dodge won’t admit there’s a issue, do a trade in and they’ll tell you” sorry the truck shakes at highway speeds and we can’t make a deal” ..... seriously?

Having same issue on a 2017 ram 1500 4×4 3 sets of tires just bought brand new rims and still have vibration coming from rear

What was your outcome with arbitration. I am sending my letter off today to Ram. They offered me a free oil change for my inconvenience

What was the outcome of this?

OK so the consensus that I am getting here is it’s the rear hubs on the floating rear axle that is the issue I’ve gone through these trucks and a family member owns another one and they all do it so I’m having them checked for a run out and balance Hope this helps you with your problem

Where was your truck built. There has to be a common denominator. Not all Rams have the vibrations

2018 3500 dually , Aisin , 410 gears 4x4. 5000 miles the shakes have started ! WTF ?

3 yr/36,000 mile factory warranty still applies, no?

I have a 2018 2500 Laramie Longhorn. I had mine custom built with everything added on. At 180 miles I asked to have the wheels balanced. Just flat spot drive it some, next time they balanced with no results. Forced balanced with no results. Mechanic rode with me and felt the vibration between 63 and 70mph. Kept it for a week with no results, new rims, tires all that stuff. Now 1 year has pasted and still fighting. Ram is saying that is normal. I understand a rough ride but not a vibration. Have you resolved your issue. I am getting ready to sign with a lemon lawyer. We have 4 times in one year with no results.

My 2018 2500 has same issue. $73,000.00 shot to hell. My dealership said Ram thinks it is the leaf springs.

I have same problem

Did you find out what the problem was

I bet its the track bar bolt holes. Once the bushings go out the bolt starts to wallow out the bolt holes. Take off your track bar and put the bolt back in the hole. Move it around, you'll see how much play. Shitty design.

Ya no gasten su dinero!! Es la flecha cardan

Mite have bad u joints
