Exactly what VNT said. Paste on the magnet means that the gears are "mating" nicely, large shavings or chunks means there is a problem. If you want to go the extra step you can pull the cover and inspect the gears. I checked mine out when I swapped the crappy stamped covers out for the Dana Advantek Nodular Iron covers. I still dont understand why they make a beefy D44 axle, and then put a flimsy stamped steel cover on it... LOLHard to say, could be anything driveline related. Pulling the diff magnet drain plug will show amount of metal shedding, if a paste like appearance probably no issue, if larger chunks , might have an issue.
I don’t know, but I doubt it. We don’t really hear people doing it.Ok. So is replacing the entire rear axle a doable option that makes sense?
No, I haven’t heard that.I heard a rumor that the LSD axle was "improved" in late 2019. Has anyone else heard that?
If this is an LSD “fix”, then the dealer should replace yours under warranty.
When do you hear the noise? I hear a clunk when at low speed and low gear (automatic, maybe around 20 MPH) and I let off gas and then press the gas again. Almost like the transmission mount were loose. I took to dealership and they said transmission was fine and couldn't replicate (BC of course!). Curious if this is the same noise/situation you are describing. Would help me get this looked at while I am still under warranty. I, too, have around 31k.I have not changed it yet. 31,000 on the jeep. The noise started about 6 months into ownership. I brought it to the dealer and did a test ride with a tech who confirmed the noise was present. He said that he had no idea what it was and that they would need to take the jeep for an unspecified amount of time to properly diagnose. As of yet I have not been interested in that route.
As I am primarily concerned about snow performance I prefer the LSD to to a locker.
