Mudge Posted December 22, 2002 Share Posted December 22, 2002 I've read that this was probably due to improper backlash settings on the rear gear. Basically I have a severe grinding sensation/noise from the rear end, but obviously this vibration/feeling is transmitting to the transmission also. Mostly on deceleration I have gear whine, but if I take it up to 5k or so quickly the noise and vibration both are pretty bad. I am fairly certain that the gears are not stock, but I haven't checked yet, due to the RPMs on the freeway though (if the tach is accurate) then I know its definately not stock. Transmission is an early 5 speed... Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted December 22, 2002 Share Posted December 22, 2002 rear sway bar with an adapter flange for GM drive shaft? The adapter flange could rub on sway bar on de-acceleration. an idea Quote Link to comment Share on other sites More sharing options...
Mudge Posted December 22, 2002 Author Share Posted December 22, 2002 No rear sway bar, and the grinding is pretty damn loud, so much so that you feel like something is going to break soon. You really can feel a constant grinding feeling being transmitted to the shifter, I can tell its coming from the rear pretty clearly though.

Guest De Schmaydee Posted December 22, 2002 Share Posted December 22, 2002 ....when and how exactly is it doin'it...decelerating w/the clutch in/out ...in all gears? "only" on deceleration...could be a bunch of things.....i'd look first at the differential mount/s and check for looseness in the driveshaft,1/2shafts(or cv's)and wheel/diff/tranny bearings....s Quote Link to comment Share on other sites More sharing options...
Mudge Posted December 23, 2002 Author Share Posted December 23, 2002 I think its only doing it with the clutch out (in gear), and in all gears. Or accellerating over about 3500 RPM or so is when the noise starts to pick up, once I hit about 5k its very loud. I'll see if it does it out of gear...

pparaska Posted December 23, 2002 Share Posted December 23, 2002 Sure it's not a broken front diff mount? Quote Link to comment Share on other sites More sharing options...
Mudge Posted December 23, 2002 Author Share Posted December 23, 2002 I'll take a better look tomorow, but I didn't happen to notice that it looked abnormal at all... Quote Link to comment Share on other sites More sharing options...
pparaska Posted December 23, 2002 Share Posted December 23, 2002 Make sure you use a pry bar to try to lift the front of the diff off of the crossmember. It can look fine, but the rubber rips loose from the metal. Quote Link to comment Share on other sites More sharing options...
