Rearend Question
I'm just wondering. when someone is talking about 9-bolt 10-bolt rearends.. are they talking about the bolts on the back cover itself?
just a quick question.
I think my rearend is at primary stages of letting go. and I'm gonna start pricing parts for it. Or if there is anyone here that could give me a decent price on an extra one they have, I'd be very greatfull.
I hate credit cards, but I can fill out a money order if the price is right

There is alot of information about rearend's on the Transmission and Drivetrain board, or even on the main page which will list all the differenct options you could have for an IROC........
If you are planning on staying with you current wheels, you'll need a thirdgen rearend.....which is ultimatly cheaper

thnx for the info.
Hmmm just another question. The reason why I think my rearend may be going. is on my way home from work last night I started to hear a whining noise at high speed (70-100 Km/h) I slowed down and in between each shift I could feel a slight vibration in the shifting lever. and heard a slight grinding while in lower gears and speed.
anyone have some info for me on this? Ever happen to anyone on here?
I'll check for answers when I get back home from work. thanks guys

The put the same number of bolt on the cover but it is called a 10 bolt because of the ring gear bolts.

The bolt cover is the easiest and most commonly used way of identifying rear ends, however when you go into detail, the amount of ring gear bolts determine the amount of cover bolts...as mentioned above....
Can't blame a business guy for giving a top-level overview.......
