Pinion? Output shaft? Not quite sure what you're talking about. The pinions I know are attached to the engine...drive the gear that spins the output shaft. I'm a marine engineer, though...usually stuff on boats is backwards. Anyway, I'm figuring that a pinion bearing is in the xmission and I'm not happy with your diagnosis...I hope your wrong. Output shaft spins very smoothly, as does driveshaft by hand with the rear wheels. Throwout bearing is very noisy tho, but that shouldn't enter into the equation...or should it? Thanks for the help, Mike


mike...rumble sounds like bearing noise....ever check to see if theres slop in the pinion bearing...?


Pulled it again today...new guibo and center bearing...u-joints have no slop, nor are they tight. Lined up the arrows, paint spots, and center punch marks (had all three)...pre-loaded the new bearing (twice)...still has audible rumble under acceleration from between the seats...and I do mean audible! I also replaced diff mount (badly in need of replacement, masked the driveshaft noise)...tranny mounts appear new, as well. She's been mine for three weeks and I'm already wishing I hadn't sold the 2002! Her rear end is sagging...she needs rear springs and shocks. Could this be a contributor to the problem. I'm needing some serious help, here. TIA. Mike
