When the gears r low on oil you can hear them chattering as metal is making contact on metal without the oil.

 

the noise is NOT normal....make them fixed...is should sound the same as stock....except maybe for a spinng tire !! haha

 

Hmm, the noise your desribing may be coming from the dust cover on the pinion flange. Did you get new yolks and driveshafts, or you still with stockers?

 

Stockers. thanks for the help.

I am looking at some images on google. Is this something that I would be able to see? or possibly fix?

 

Actually, you could put it up on jack stands, or have them put it on a lift. Crank it up , put it in drive and try to find the location of the noise. Careful if do this yourself, make sure the front wheels are chocked, it's not in 4wd, and you have a person in the driver seat to control gas and brakes. As others have said, you should have no noise with a new gear install. Does the noise seem to be coming from the rear or transfercase area?

 

It is coming from the rear transfer case area. Hard to pinpoint. when I picked it up yesterday, I actually turned right around and brought it back. They did just what you suggested. They picked it up in the rear and as they picked up speed the noise was easy to hear. They just told me that it was normal. I even told them, "there is no way that is normal". He said, 5.13 gears always make noise.

But to me, it does not sound like anything mechanical. It sounds like something is rubbing.

Any suggestions? Especially when the shop keeps telling me everything is fine.

 

Hmm, you have 4dr and I highly doubt your stock rear ds cv joint is messed up. If it seems to be coming from that area, do you know if they completely removed your rear ds for the gear install? I really doubt they did , unless they didn't feel like tying it up to keep it out the way, but I'd ask them anyway if they took it completely off. Still, doing that wouldn't have affected the dust cover on the flange. So, I'm at abit of a loss as to why you have a noise there. Unless that upper rzzeppa cv joint is prematurely starting to go. Just as a precaution I'd check the oil level in the tcase.

 

really appreciate all of the help. the jeep has 600 miles on it. I can't imagine that anything is going. I will be sure to update you when I figure this one out.

 

Well damn, for sure keep us posted. Only 600m. Hell, if anything check that oil.

 

Would not have made the 750 mile trip without the new gears. They still make noise, and I plan to replace the fluid this week. See if that works.
