Something is off

Hi all, I am preparing the axles for a Savvy lift and have the axles sitting on stands, the pinion yoke is pointing straight down in all pictures.
I noticed when I spin the axle by the wheel studs it's not spinning freely all the way around, there is a zone where it's tight and hard(er) to spin by hand, which I imagine causes the slight vibration I've felt while driving.... I cannot determine what/where the issue is, so I'm just posting my observations in hope of someone can see what I can't.

When I loosened the hub bearing bolts the axle spun more freely.

When removing the 3 hub bearing bolts and let the hub assembly sit where it naturally want to sit, it doesn't sit straight in the steering knuckle, notice the angle.

And when tightening the 3 bolts, eliminating the gap, the axle tightens up and it's again hard to spin it.

I also noticed the axle is not sitting centered in the axle tube - can this be because there is no weight on it ?

I put a straight edge on the axle tube and the axle shaft itself and and those appear straight.

The driver side axle has some of the same symptoms, but not as much as the passenger side.

Any ideas

A few. If you can determine that the axle housing isn't bent, then that leaves two other options. Inner C is trash and holding the knuckle some place it doesn't belong. If you don't find that to be the case, then there are instances of yokes being machined off center on the axle shafts. Spin the unit bearing bolted up and see if the yoke moves up and down.

Just spit balling here, but couldn't this also be an axle shaft u-joint issue?

Thanks for the replies guys, I haven't had the time to tinker with it. I am a bit over my head with projects so I'll bite the bullet and let a pro fix it, just so I can get the Jeep running again.

OK.... I finally got the diagnose from the 4x4 shop, it is indeed the 'C' that is off by a few degrees, holding the steering knuckle where it doesn't belong like Mr.Blaine predicted. The axle tube itself is "straight" per the shop.

The shop offered me 2 solutions:
  1. Reinforce the damaged 'C' and install a sleeve to minimize chances of bending the axle tube in the future. This is in addition to a truss I need to weld on.
  2. Get a new G2 axle housing and move the gears, axles etc. over - this would cost $2600 for parts and labor. BTW, they are G2 dealers.
Currently the axle bearing bind up a little at about half way of the rotation, to the point where it creates some vibrations which I'm not sure I want to accept - I assume this won't be solved with option #1.


So since I am potentially looking at a major expense, I am would be willing to "gamble" a little with the axle housing i.e. try some methods that might or might not get the 'C' into an acceptable position.

[edit] This seems to be what I need or ?? https://craneaxle.com/crane-axle-dan...e-inner-c.html


Any ideas are greatly appreciated.

What axle is currently under the rig and what size tire and trans do you have? What gearing are you after?

The axle is the stock D44 with 4.11 gearing. I run 33" tires and the transmission is the 6-speed manual.

How much would the shop charge you to cut your inner c's off and install the Crane units and reassemble everything?

They would charge $470 to disassemble the axle, and approx. $600 per side for cutting and welding, adding the price of the new set of C's I'm close to the price of a G2....ughh

I had a feeling that would be the case. Do they have any other options besides G2? Like the Currie Rock Jock axle etc.. Also you could maybe try Daveys Jeeps and see how much another stock axle housing would cost you instead.

I will definately contact Daveys Jeeps to see if they have something more in my price range.
Right now I think the option that fits me best is to get the axles back from the shop.... ohh, they only sell G2 axles BTW
I will get the current C's off myself, purchase a set of new C's get the new C's on the axle, prepare everything for welding - then take it to a welding shop with experience in axle welding and hope for the best.

I'll try following the disassembly process from cutandturn.com

Good luck! I can't weld myself, but I work with welders, and there's deffinataly a lot more to it than just melting globs of metal together. And as you already know, just getting everything aligned correctly isn't 100% especially if the factory got it wrong.

Yeah, I have welded a little (and I mean a little) and know that I shouldn't attempt this myself.. It's not the factory that messed anything up, I think the Jeep has been hit in the front right side and that messed up the C.
