I put everything together again with new grade 8 bolts. Im sure I have the pinion gear depth right and the clearances right, but it still whines. Its not too loud but when your foot is slightly on the gas, the gears humm. Plus the rear end gets really hot. The directions say that new gears will cause excesive heat especially on numerically higher gears, so they say to break in the gears by driving 10 miles, stop, and let the rear end cool for 30 mins, and repeat that 4 or 5 times. Hopefully that will solve the heat problem but what about the whining? Should I just leave it be or bring it to a shop? Im sick of taking this thing apart.

I'm no rear end specialist but I do know the rears we put together at work do not whine when done. We generally consider that a problem. On the other hand when I was getting ready to buy the ring & pinion set for my car more than one person I work with said that they'd had problems with noisy richmond sets. I ended up getting a set of precision 3.70 gears from Randy's Ring & Pinion online. Not only do they not make a sound but the only break-in I did was to just get in and drive. Truly sorry about your loss though, money doesn't grow on trees to fix these things.

I had sort of the same problem with a '56 Bel Air hardtop a while ago. Had a whine that was growing louder and couldn't pin it down. Was a well used stocker as opposed to your new one. Took the third member out and looked a the gears and they were perfect. Finally got frustrated and took the whole thing apart. Found the carrier bearings were badly pitted. Replaced them and things were fine. If your gears are true as you say I would suspect the bearings. Can generate a lot of heat in them if they are set up wrong - too tight or too loose, or damaged.

generaly a bearing will whine on power and coast, while the gear set can be just one or the other.
could have caused damage on the initial failure.
the mufflers are on either side of the pinion yoke on your car, aren't they? if so, that can contribute to some of the heat.
i have installed gear sets that were noisy, sure that some thing was wrong, i opened them back up, took a tooth pattern and back lash, had my boss double check. they left that way, and the customer is happy.
i would recomend a doubble check of tooth pattern and backlash, maybe a test drive at your local drive line shop, or a second opinion from someone you trust..
then run them untill you have time, money, or need to replace them.
i personaly would be concerned as to their structurial integrity after their first failure.
good luck.
maybe not wasted, could just be paying for education. we all have done that!

The mufflers could be the heat problem. Im going to pop the cover off this weekend and double check everything one last time. If I don't see anything wrong, im just going to put it back together and drive it the way it is. Ill just keep some extra money in savings just in case it does break. If it does break, Im sending it right to the shop and Ill get everything done right by a pro. Im just plain sick of it. Thanx for all the replys. I really appreciate the help on this forum. If I knew you all, I would buy each of you a 6 pack of beer. <img src="graemlins/mwink.gif" border="0" alt="[mwink]" /> Thanx
