How difficult is to replace pinion + ring?
I have the original GM manual + a special GM publication about that.
Theoretically it's all clear, but how it is practically? I don't have the tool to measure the diff casing and I'll have to go by try-and-error using the shims.
Is it that difficult? Or is it better to go to a garage?

Thanks - Stefano

I've seen experienced people screw it up. Go with the best place you can find.

The home mecahnic can accomplish this task with the correct tools,but you need to know what your doing and have experience doing it. The gears need to be with in close tolernaces (preload,backlash etc) like +/- .001 If you are slightly off the gears will whine, the contact pattern will be jacked and the rear will most likely fail. Find the most reputable guy you can pay the $250 gear set-up and be done with it.

Here they want $800 for parts and labour...
but it's true: a little error and I screw up everything!
Is it necessary to adjust it differenty if the car has more power than stock?

I have done about 5-6 sets. First two with help from a freind and the rest on my own. The GM 10 bolt rear is pretty easy. Buy good gears and an installation kit. Some come with a video and it's step by step. I used the stock shims over in every case I believe and they all are still going today. The only gears I did that didn't whine were GM gears. Point being, its really not that hard.

Do you know the brand that comes with the video?

You mean the cast iron shims? GM suggest to replace them because they can brake easily.
In general: this of adding shims and check the pattern on the *****... how often does it happens? I was thinking it was necassary to adjust every new set of gears, or you can usually reuse the old shims?
Remove / press the bearing is not a problem, I have the tools.
I just want to avoid to remove them too many times until it's OK.

A pretty serious tool set and several very specific measuring devices are required to do it.

I did mine just about a month to a month and a half ago. A bearing press is a HUGE help as when you buy the necessary install kit, you need to replace the various bearings that are in there. The Ratek kit includes everything you need. It's not for a beginner by any means though. IF you are going to attempt it, make sure someone is there that has done it before to help you over the speedbumps that ARE going to come up.
