southsidemex23 Posted July 1, 2009 Report Share Posted July 1, 2009 well for th past couple months it seems like my rear diff has been getting worse and worse. this past weekend i took a drive down to san diego and when i would go over 80 mph it seems to have a humming effect coming from the rear of the truck. it also has a strong buzzing with it. once i back down from 80 then it kinda goes aaway. the higher the speed the louder it gets and the more vibration i feel. i suggestions? here are some pics from yesterday when i removed the cover. there where no big chuinks of metal just this stuff. ring and pinion gears look fine no missing teeth. just a glob of metal Quote Link to comment Share on other sites More sharing options...
benjaminh2 Posted July 1, 2009 Report Share Posted July 1, 2009 That amount of metal on the magnet looks a bit excessive. i'd tear it appart and inspect all the bearings and races, theres a prob somewhere, especially if you've got a noise.

southsidemex23 Posted July 2, 2009 Author Report Share Posted July 2, 2009 its actually more like a humming noise. like when something is out of balance. how hard is it to replace the bearings and races. if its a bearing i think it might be the pinion gears bearing or what do you guys think? would the actual lsd go bad? the ring and pinion gears look fine no unsual markings.

benjaminh2 Posted July 2, 2009 Report Share Posted July 2, 2009 to locate the source of the noise, run it in gear up on a lift. use a stethascope to pinpoint where the noise is loudest. i've used this method for years, hasnt failed me yet.
