Weird noise and diagnosis.

So the last week I noticed a strange noise...sounds sort of like rubbing/jingling bells with shearing scissors. (I know, weird description). It is similar to a noise when something is rubbing on a rotor. After checking all the brakes and not being able to diagnose it, I brought it to Jeep this morning. To me, it sounded like the noise was coming from the front end (but since it was under the car, it might have echoed from anywhere.)

So, after a bunch of testing and running it on a lift, they conclude the noise is coming from my rear diff. I just installed a Riddler cover on it the other day, and didn't see anything out of the ordinary, and there was no abnormal amount of filings on the bolt. The service guy tells me that he will replace it this once, but if it happens again, don't bring it back with "those tires." Those tires are Duratrac 33x12.50x15 on Level 8 trackers, which weigh the same as an OEM setup on a rubi/sahara and I haven't taken the rig through anything anyone would call abusive.

Do you guys really think that 33" duratracs can cause a D44 to fail? I think something is loose inside, but I guess they would rather replace it than fix it.

Any opinions? I know Im getting a "free diff" but Im always a little apprehensive about dealers replacing parts since often times they cause more problems than I started with.

This is on a 2012 Sahara with an open D44.

Spin the tires up on stands. The parking brake internals can make some weird noises.

If the noise started happening after you put the cover on. The differential might be rubbing against the cover.

No it was rubbing before. Probably a bad pinion bearing or something but the dealer is replacing the entire axle. Go figure.

I see no way those tires could cause a properly set up diff to go bad. Tell the service guy to lay off the crack cocaine. LOL

The only reason I'm keeping my mouth shut is that they are replacing the axle. If they gave me grief, I'd be throwing things. Until then, I'll just be Chuck Norris and wait.....

Those tires should be fine - pull it up next to a stock Jk, there should barely be any difference between those tires and the stock Rubicon tires. The guy's a douche.
