rear diff carrier ls

[Bartlett]

My friend has a 04 2500 (hemi) that he felt a funny shudder in while cornering so we brought it in and pulled the cover. Looking at the diff carrier (limitid slip) on the right hand side we can see what looks like three gears each with what appears to be a pin that has worn thru the case. Each gear/pin is eaqually spaced around the circumference of the carrier with the "pin" being slightly above the "gear". We jacked both wheels off the ground and while spinning one wheel the carrier spins as well as the gears. The gears have worn into the carrier from the inside out causing very sharp edges. This definetly does not look normal to me but i am not familiar with this at all. It would almost seem as if there was no thrust washers to keep this side loading condition. Has anyone seen this before?Also didnt find any unusual metal in the housing/fluid.

Take a look at this thread. It explains alot about the AAM differential. What your describing is a normal rear. The gears only appear to have worn into the carrier.

Also I read somewhere (TDR I bet) that the carrier has been ground to allow clearence for these gears, it might look like wear but they say its not.

Well that is interesting reading. I have never seen anything like it and have been a heavy truck mechanic for 17 years. The sharp edges dont seem normal though. He is bringing it to the dealer to have looked at anyways. Thanks for the info.

Don't tell them you had the cover off or they will most likely give you grief if he is looking for warranty work...
