AstralRT Posted November 4, 2015 Report Share Posted November 4, 2015 I've just started hearing grinding noise and clunking from the rear of my 2012 DJ R/T. The grinding happens when accelerating from stop and more when turning from a stop. The clunking happens when starting/stopping at slower speeds. Is my rear diff done for? What's an avg cost for a repair/replacement? dhh3 1 Quote Link to comment Share on other sites More sharing options...
bigtsr Posted November 5, 2015 Report Share Posted November 5, 2015 Well if your still under 100,000 kms with a 2012 it should be covered under powertrain warranty. There were posts about the rear seal failing and losing lube. jkeaton and dhh3 2 Quote Link to comment Share on other sites More sharing options...
AstralRT Posted November 5, 2015 Author Report Share Posted November 5, 2015 Unfortunately I'm just over 150k now, no more warranty dhh3 1 Quote Link to comment Share on other sites More sharing options...
jkeaton Posted November 5, 2015 Report Share Posted November 5, 2015 Take it to the dealer or a shop you trust. dhh3 1 Quote Link to comment Share on other sites More sharing options...
B4ZINGA Posted November 5, 2015 Report Share Posted November 5, 2015 Crawl under on a dry day and check all driveline components for signs of leaks Front and rear axles, front and rear differentials, transfer case, drivelines, trans itself. How long ago did you have the axle, PTU, trans fluids changed? If they're near the end of their service lives (or past it), change them out and see what happens. Beyond that, shop time. Try an independent mechanic, as the dealer tends to be expensive and would likely just tell you to replace the whole shebang without even looking at it. dhh3 and OhareFred 2 Quote Link to comment Share on other sites More sharing options...
jkeaton Posted November 6, 2015 Report Share Posted November 6, 2015 I would take it to the dealer or a reputable shop for a proper diagnosis and cost estimate. dhh3 1 Quote Link to comment Share on other sites More sharing options...
dhh3 Posted November 6, 2015 Report Share Posted November 6, 2015 On the AWD DJs, is the rear drive shaft, rear differential and rear 1/2 shafts always turning, whether AWD is engaged or not? jkeaton 1 Quote Link to comment Share on other sites More sharing options...
Lobitz68 Posted November 6, 2015 Report Share Posted November 6, 2015 On the AWD DJs, is the rear drive shaft, rear differential and rear 1/2 shafts always turning, whether AWD is engaged or not? I believe so. dhh3 and jkeaton 2 Quote Link to comment Share on other sites More sharing options...
dhh3 Posted November 7, 2015 Report Share Posted November 7, 2015 My Nitro was like this. It was basically RWD. All of the front end components were always spinning. There was an electrically operated sing speed transfer case which would engage the front drive sfat and lock it to the rear drive shaft 50/50 torque split. It was part time - no center differential, so it could only be used on slipper surfaces. Quote Link to comment Share on other sites More sharing options...
