9 1/4 rear: Running great!
« Reply #15 on: November 24, 2009, 05:29:56 PM »

I've done a few 8 1/4's and a couple of 7 1/4's, but never a 9".
 
I would get a kit with bearings, shims/crush washers and seals along with the gears.  Then follow the FSM.  You'll need a dial indicator to set the end play of the pinion and lash on the ring.
 
It will go, but not set up right, it will make noise.  The good thing is you have a lift.  I do this Shtuff on my back.
 
BTW, the ring gear bolts are left handed

The hardest thing to set is the pinion depth.    When you don't have the right depth setting tool the smart thing is to re-use the original shims at the rear of the pinion.

The bad thing is the shims are behind the rear pinion bearing & it's pressed on & off so if it's off you have to pull it to change them.  Starting with the originals ( with a factory gear especially ) is usually gonna get you really close.   The front bearing just slips on.  Then there's the crush sleeve,  it's a one-time only use so if it's wrong you replace it.   I don't know if they make a solid spacer like they do for a 489 8 3/4.

the adjusters in the carrier make that an easy one,  after they're snugged up you use the dial indicator w/ a mag base to start checking the backlash ( usually around .008 ) ,   you turn one adjuster in & the other out thus moving the carrier left or right to get the backlash.

You'll need some way to hold the yoke when tightening the pinion nut,  close to 200ftlbs If I remember.   What ever the book says.   Ring gear bolts left handed as Steve said & make sure the carrier bearing caps are marked so as to go back in the original positions.

If it was me I'd use the original shims ( or measure them & use new ones of the same thickness ) & try it.   I bet it'll be OK.

Forgot,  we just make the carrier adjusting tool to use on a 8 1/4.    Long pipe with a handle at the end & a hex at the other but then if that tool is that cheap I'd just buy it!

Stanley, my Brother-in-law has the same dilemma with his Camaro.  He wants to dump the 4.10s for a set of 3.26s.  I suggested he find a guy who has that set on his car and do a swap.  Heck, I told him I'd come to his house and do it for him/them.  But, he not wanting to do so I suggested he ask around and see what the price would be at a shop.  He found a shop that would do the swap - performing all of the work - for less than $900.00.  I told him that's a great deal!  The shop has a great reputation in the Sacramento area.
 
I know this much, I would not attempt to do that job with so much at stake.  It seems daunting, and I'm sensing the same by your previous post. 
 
Is there a shop in your area that would do the job?

Well,  there ya go....if you're not at all comfortable then let a good shop do it.

If it was an entire rear swap that's a piece of cake.    As long as the rears are from the same exact car.   The hard part is finding one for your particular car with the gear you want & not already worn out to where you wind up having to replace the bearings anyway.

This way at least you'll know it's all fresh inside.
