I'm working on a really detailed writeup...but that won't finish until I finish my install...and currently I've been dealing with a busted thread on my pinion for the last 2 weeks and so pissed I'm about to take a grenade to the car...

BUT...I'll give you a sneak peak at my writeup by giving you the parts and tools list (it's 22 pages so far, without pics, and I'm only at the backlash part, so it's gonna be big...

By the way, the writeup includes diff, u joint, and PHB, so there may be a few extra parts/tools than you need.

Thanks that will surely help. I have someone to do it for me i just need to make sure i gather all the parts before i take it to them. I have GM 4.30 gears. Is there somewhere i can just buy a complete "install kit"??

What is: (note 1) and (note 2)?? Also do you know how many bottles of GM additive i need?? So far I've read i need 2 i just want to verify.

You can get a complete install kit from Summit.

NOTE1: If you don't buy the kit, you have to buy some of these separately. You really just need the pinion and carrier shims, marking compound & brush, and crush sleeve. The bolts and pinion nut you'll be using from your old diff. See NOTE2 about the oil seal.
NOTE2: The design of the yoke changed in 2001. Apparently, some 2001s are said to still have the older version, and some have newer ones. The shaft of the yoke that goes into the housing (through the oil seal) is slightly larger in diameter than the older ones. This means that your oil seals will be different model numbers, and if you get a Pinion Yoke Repair Sleeve, it'll be a different part number as well. The appearance of the oil seal you have installed will be the dead giveaway. The newer models have a collar placed inside the yoke. I've read that people can remove the collar (pry it out with a flathead screwdriver) from the yoke and use the older design, but with National brand seals being fairly accessible, I'd just buy the right kind for your car. Timken and the one that comes from the Motive Installation Kit (and all the other installation kits I've seen) come with the older design.
NOTE3*: This is the part number for the older style yoke. I cannot find a redi sleeve for the newer style. You only need this part if the shaft on your yoke has a groove in it. So, if you have a newer style yoke and you've got a groove, you have to buy a new yoke. Look for one matching a "Mech 3R" U Joint specification. They seem to range from about $65-100.
