More problems with the shop that did my re-gear

[Sticks702]

I have spent too much on the rest of it to do that. I will just have a new set of axles built by a reputable shop if this isn't made right

Well this saga is continuing. Something popped in the rear diff today, accelerating from a stop light, and there is now a significant vibration in the driver's seat at anything above 40mph that gets worse with speed. There is also a screech under the initial accel, a "whirr" when decel/ coasting, and a distinct whine backing up in reverse. I know I am new to this, but it seems like it is even more screwed up than it was before. WTF is going on here?

You lost a tooth, best bet. They’ll be doing all that work again.

Yeah pretty much what I was thinking as well. First time around they put too much preload on the pinion and smoked the bearing. I can’t believe a pinion that had that much play didn’t cause other damage. Hopefully it didn’t hurt the Eaton lockers

A few days ago, I posted about the service 4WD system light coming on in 4L after a re-gear. After programming in 5.13 gears this issue "seems to have gone away", but I have not had the chance to trail test it yet as there is now a new issue. My lack of faith in this shop is increasing. So after I picked up the Gladiator from the shop that did the work, on the way home, I started to hear what sounded like a bearing whine, metal on metal turning into a screech. I immediately took the Jeep back and took the service manager for a ride, and he said it sounded like the caliper backing plate was rubbing on the rotor and to let them have it for a few more hours, They called me to come and pick it up and said my steering stab was hitting something moving and they rotated it and fixed the issue. The steering stab is not close to anything that could cause that noise, but I picked it up anyway. I drove out of the lot, and low and behold, the noise was still there and getting worse. Took it back for the third time, and they kept it overnight. They called me yesterday and said it was the pinion bearing, and they had a new one on the way in. So obviously, they put too much preload on the pinion and smoked the bearing. I asked that before they button it up today, they provide me with the specs for preload, pinion depth, and backlash, as well as another photo of the gear pattern. I was told that since they were just doing the pinion bearing, they did not redo any of the gear installs and did not have those numbers. Am I crazy to think that the tech that did the original install would have these numbers written down in my file in case anything went wrong? I got a labor and material warranty on the work from them, which, at this point, seems like a godsend. I am at the point now where I want to take it to another shop, pay them to tear it down, and put it back together again to the correct specs because I absolutely no longer trust the shop that is doing it. If I do, and find that it is improperly done, again, do you all think I would have any legal recourse against the shop that did the crappy work? Getting very frustrated. I spent a fair amount of $'s on gears and lockers and now I am gonna be afraid to drive the damn thing.

You cannot change a pinion bearing without installing a new crush sleeve….. you cannot install a new crush sleeve without measuring the pre-load…. And the gear wear pattern is smearing more paint on the ring and giving her a couple forward backward spins…. All could have and should have been done.

I know this is a bit of a drive across town… I literally drove from Ridgecrest down to these guys because of how good they are….

Check out this place on Google Maps https://maps.app.goo.gl/fR6FQUL6ZENrGFZd9?g_st=ic. <- disregard, I thought you were coming from north west LA not Vegas…. Too far for this. Leaving it for anyone else in So Cal in need.

Thanks for the recommendation! Though too far for me, I’m sure someone will be able to use them!

It has been parked since the latest episode and is in the new shop today for diag/service
