First off, thanks for all the great information you all provided. I started to hear a " howling gear noise" coming from the back of my 2003 Ram Quad Cab (5.7 Hemi with 3.92). With all your great info about the LSD retainer clips, i pulled the rear diff. cover and found 2 full clips, and 1 partial clip on the magnet along with lots of silvery fluid. So obviously something is really screwed up (the noise is pretty loud) and my 7/70 warranty expired 2 thousand miles ago so i have to foot the bill for this. Anyone have any idea how much this will cost me? i don't want to go to a repair shop "blind" and get ripped off. Thanks!
