Rear End Re-Build - 4th F-Body

94TAGT · August 3rd, 2010, 10:45 AM

So at 69K miles my rear end is getting rebuilt! The pinion seal was leaking so after it was replaced by the transmission shop it began to howl. So I told them they over tightened the yolk which they said dthey torqued it to spec but never checked the pre-load. Well they tore the rear end apart and the ring and pinion have a 1/4 inch gouge on the top edge but the ring is perfect. I only drove the car 40 miles with the howling so there is no way it came from what they did. I talked to my father-in-law who rebuilds tractors and he confirmed the same thing that the gouge was there a long time ago. He said someone else had to of messed up the bearings and it found its own grove and never howled for me until it was done correctly and everything was placed back where it should be. So since they have it apart, I am getting all new seals and bearings and a new ring and pinion. This thing is gonna run smooth! LOL!!!! All for about $800. The other bad part is I didn't think about getting a 3.73 until it was too late. So I am still going to be running the 3.42's.

that's almost halfway to a 12bolt and 9in... you couldn't have just saved?

My brain was all over the place! The rear end was already dismantled so I had to make a choice on the spot. I would have just saved and did the 12 bolt but it just was not in the cards at this time considering I am moving to Colorado TODAY!! LOL!!!! Final price with tax was $950. She sure is smooth now though! I think the rear end will outlive the rest of the car now.

I wouldnt bet on that, a pair of stickies and a couple good hard launches at the strip and that 10 bolt will puke its guts out. If your nice to it than you should never have a problem but wheres the fun in that?!!
