Alright, some of you may remember an older post I mad about this issue. When I got my 95 mark (base) I had a vibration at 100+. Pulsating "voom" sound. Changed the gears to 3.73 and now the same sound comes in at 55-60 goes away and then comes back at 85. Here's what I've replaced... Driveshaft (replaced with a 93 one piece), all bearings seals and races in the carrier, both half shafts, both rear wheel bearings, tires, IRS carrier bushings, engine mounts. Today I took the car in and the guy put it on a lift and had someone drive it at 85mph while he was standing under it (shetchy as hell). To make it better, he placed his hand on my transmission. He said there was zero vibration from the transmission or the drive shaft, so we moved to the rear. You could see the carrier, half shafts, lca's, etc shaking. After looking around he narrowed it down to the pinion flange. He said it looks like there is a slight wobble going on with it. Could this have been defective from the factory? Would it cause this kind of vibration? I know it is cast and I wouldn't assume that it got bent.. His advice was either the flange is warped or the carrier is warped so he is trying to get me to buy a new carrier. Anyone else experience something like this? Should I start with the flange and go from there? Flange is $30 and we all know how ungodly expensive a carrier is. Thanks guys!
