 The 9.25” limited-slip differential in my wife’s 2002 Dodge Dakota crew cab failed after components of the differential disintegrated at about 75,000 miles. It’s a daily driver and my wife has never abused this truck. This failure could have resulted in a catastrophic failure if a very slight noise had not developed during parking lot turns. A quick Google of this problem resulted in numerous antidotal reports of this problem including catastrophic failures at highway speeds. I am having the dodge components replaced with an Auburn unit so this doesn’t happen again.

Replying to: davec5 (Sep 12, 2007 3:42 pm) The somewhat common complete failure is the C-clips breaking (or C-locks as Chrysler calls them) and the pieces chewing up a gear, or noise caused by pinion bearings wearing prematurely. Noise complaints are the most common. I'm not sure but my guess is poor assembly at American Axle. More seem to go forever without making noise so I suspect it's not a component quality issue. Chrysler finally got tired or got the point regarding their differential assemblies and is building a new facility dedicated to making their own axles once again. It will also be their own design and reported to be quieter and less friction than current designs. I think they'll be available on the 2008 RAMs. Hopefully the Daks will get the new rears. Best regards, Dusty

Replying to: dustyk (Sep 13, 2007 4:43 pm) I just had the gear oil changed 3 days ago, Mobil 1 synthetic 75-90 and the friction modifier was added. I was watching them change it, and there where no pieces of metal in it, except tiny, tiny little pieces, they said that was normal. I also had them change the transfer case fluid, added was Valvoline ATF+4 synthetic. Immediately after leaving the garage a noise started. Now, I can't tell if the noise is coming from the rear end or the transfer case. But while shifting through the gears, when I hit 3rd gear the noise starts. It sound like an "air noise". You know how some cars will make an "air noise" out the exhaust, I had a 73 Torino that did it. It sounds exactly like that. I know that sounds kind of weird, but I can't possibly explain it any other way. Do you have any clue of what might be causing that?? The only other noise it started after having the fluids changed, is when making a u-turn on damp grass (in my front yard) it clunks and jerks. This I know is coming from the rear end. I don't understand, because I know they added the friction modifier, I watched them put it in as well as the Mobil 1. There is no noises while turning sharply on asphalt. I would surely appreciate any help. I am so worried about this 9.25 lsd problem. This is my only vehicle and it is my daily driver. Thank you so much, Lu
