Dana 30 Rebuild Guide Pt.1: K Suspension Axle Truss, IRO Axle Sleeve, Cut n' Turn (FIX YOUR CASTER!)

3 жыл бұрын

In this episode we begin the rebuild of my Dana 30 axle. We will install a K-suspension axle truss, iron rock offroad axle sleeve, and will go through the process of cutting and turning the axle C's to correct poor caster angle in a lifted jeep. Next episode we will completely rebuild the differential with Yukon 4.56 gears, Yukon master rebuild kit, and Powertrax No-Slip locker.

Thank you for the thorough video. Put my mind at ease about tackling my axle build.

Got to be a lot of work cut and weld the C ‘s yet you don’t have to worry about the drive shaft angles to transfer case. Set your camber only once. Buy longer saw all blades will help. Preheat both pcs with a good rosebud, torch set up get about 450 degrees, weld it and wrap up the weld area with a asbestos blanket it’s not the same kind of asbestos. Where you have to worry about any fibers getting into your lungs. Slow cool down is the best welding cast steel. If it’s cast iron use a high nickel compound welding wire or a stainless steel wire using argon gas. Other wise you can get weld rejection, cracks, holes within the weld.

The reference angle from the face of the diff cover is irrelevant. As long as your initial markings are at the stock position, you could have just zeroed the angle finder on the Inner C and rotate from there.

I know it's a three year old video, but I have to point out some errors. The axle is suspended by parallel links. So as the suspension extends the pinion does not stay pointed at the transfer case. It drops vertically and keeps the same pinion angle relative to the frame. Vibration is caused by a disparity in the angle correction given by the U joints at each end of the driveshaft. 'Aiming' the pinion at the transfer case causes the problem. Lowering the transfer case will help with driveshaft deflection angles. The rotation caused by lift kits is due to engineering mistakes in the less expensive kits. It can be corrected with adjustable links. When the lift goes beyond 4" it is time to go to long arms. Not because of pinion angle, rather to keep the front axle from swinging back towards the middle of the vehicle.

Wow, awesome video mate, I was thinking about doing something like this myself but never thought about cutting the C's off. I was thinking about drilling away the spot welds that hold the tubes in place (if there are any welds at all) and pressing the tubes out of the pumpkin, rotate them and press them back in again and weld along the sleeve of the pumpkin so I keep the C's untouched.

@trailandco 2 жыл бұрын

I think this would be better than what I did if you have the means. That or do the same at the cs, press out and rotate. My method has worked fine strength wise but as far as alignment was not nearly as accurate as it would have been had I been able to press them back on the tube.

Harmonic balancer puller works great for removing pinion yokes. Might have to buy longer bolts with the same thread as your pinion yoke. Before I had the right too to hold the pinion yoke for reinstallation,I used a really old large pipe wrench that I picked up at a garage sale about 25 years ago. It is about 3 feet long, and it's bent. Every time I use it, I can't help but wonder how the heck it got bent. It's gotta be the oldest tool I own. Maybe it got run over by a 🚂

could you comment about the way the steering feels with proper caster versus not enough. thanks .

@trailandco 2 жыл бұрын

Proper caster will keep you driving straight on the road and will allow your steering wheel to return to center after a turn. It's a great improvement to the drivability of the jeep, otherwise it wanders all over the highway with low caster

@trailandco 2 жыл бұрын

On one hand the steering has held up great super strong and have had 0 wear issues with the heims. However next time will go with TREs, I don't like how the tie rod bounces around freely and makes noise. It was a pain to silence it. Cavfab does not cause death wobble I would do more research to find your issue

@pochopdaddy5667 3 жыл бұрын

Just wondering? Just rotating the knuckle, doesn't that throw off your spring perch angle?

@oleroy4749 3 жыл бұрын

Not if done correctly. All that should change is the angle of the inner C’s, if your math is rite.

@jeffd1467 Жыл бұрын

@Ole Roy I had the same question. It's impossible that the spring perches didn't rotate. They would have rotated just as much as your new pinion angle did. I'm assuming that you rotated your pinion to align with the driveshaft. It must have been out of alignment prior to the cut. It seems like cutting near the diff would eliminate this issue. Is it possible to cut near the diff?

Seems like this method would really weaken the axle at the weld point. Is that why you put the axle sleeves in?

Yes. The sleeves alone are thicker than the base axle housing so all in all I believe the end result to be far stronger than the original

I would love to but unfortunately the bolt in dana 44s are impossible to come by around here unless you want to shell out 5 gs for a dynatrac. At the time D44 didn't seem worth it for my purposes. Now I'd like to move to 35s eventually and would consider it if the d30 ever gave me issues. But this axle has been awesome

Is a stock Dana 30 axle (not trussed, sleeves, no HD ball joints) strong enough to run 35’s and be able to wheel moderately?

Many say it is. I'm only on 33s so I can't speak to it. But I think the rule of thumb is 35s you're ok if you stay off the skinny pedal

@@ProjectXJ Yeah I thought about putting a truss on my Dana 30. Probably well worth it in the long run. But eventually I think I want to run 37‘s so I will definitely have to do away with the Dana 30 and upgrade. But I agree, I’ll probably just wait until I absolutely have to replace some thing

I was thinking this was overkill too. My XJ is about 6.5” now on long arms, on 33s going to 35s now. Alignment is within spec and drives straight down the highway, barely have to touch the wheel, no vibrations either from pinion angle. But if it works for him and it’s what he wanted, more power to him.
