I use a pinion depth gauge to get the pinion set.  Kind of an expensive tool for someone that doesn't plan to set these up very often, but necessary to do correctly.   The pinion bearing on GM 10 and 12 bolts will need to be pressed on and off several times to change shims so a good press with a bearing splitter/clamp is needed so the bearing can be removed/installed without damage.  Or take an old pinion bearing and slightly hone the inside so it slides on and off.  Once you find the correct shim arrangement press on the new bearing once and done.   From there you'll need a really strong impact gun to get the crush sleeve to start to compress.  Once it starts to compress then it becomes fairly easy to tighten and set pinion bearing pre-load.  I shoot for 30 inch lbs on new bearings.
    With pinion depth and back lash set I then check the pattern with marking compound just to see how things look.  Backlash is tricky because bearing preload also has to be taken into consideration on the carrier as well.
   Just did mine a couple weeks ago with the transverse muffler in place.  Removed the shocks and the rear drops down enough to remove and reinstall everything.  Not my preferred method but do-able since I have a lift.  I prefer the rearend out and up on the work bench though.  I definitely don't care to do them on my back anymore.

Thanks for the link to the car Bill.  23 certainly looks a lot different now, but I don't know how much of its life it spent in lavender.

You know you can copy the picture above and save it to your files,  or are you wanting the actual photograph?

Looks like Mike has beaten me to it..

  Sounds like you've been down that road before too.  ;D
To the OP. It's a lot of work and a big disappointment if you go through the whole effort only to take a test drive and hear either clunks on acceleration or coast, or the dreaded 'stud' noise one can hear when driving on a bridge with a studded grate.

Wow, sure glad there are more skilled and knowledgeable guys out there than me who are willing to share. I'll heed your advise and have a pro do it. Thanks so'll be hearing more from me as I work on my car.

Several variables you have to think about...  Are you gonna be laying on your back or will the car be on a lift?  Does the car have a transverse muffler?  If you have never done it before I would suggest having someone help you that has or watch it being done by someone that knows what they are doing..  You can get the backlash correct and still not have the pinion depth correct and itll howl going down the road.  Also need to make sure you get the pinion preload correct or you will cause bearing failure..

Looks like Mike has beaten me to it..
