I loved the way the crossmember tool loaner program went and it helped a lot of people.
I thought this could be sort of similar.
If anyone else is brave enough to tackle rebuilding their own diff, you will need a couple of specialty tools.
Why buy them and have them collect dust for years after?
I will document what is needed here, and offer up my tools for the program.
I do not plan to ever build a diff again.
I also made a few bearing & press tools that are useful, and will include those as well.

Because this process could take a while, I suggest you buy the tools first. I will offer my tools up at half price, or $160.
(The must-have dial inch-lb TQ wrench was $180 alone.)
Then just pass them along and sell them back to the group when you are done, for the same price. So no cost to you!
I only ask that you try to keep all of the tools together to help out the next person.

First Pic:

(Top row) 0-30 in-lb Dial TQ wrench $180 value, (2nd row) pinion holder TQ bracket, Rockwell Hardness Tester File set $70 value. posi rotating tool - homemade, posi holder - old worn out yoke, 28" breaker bar (I removed the not very useful beam TQ wrench)

Second Pic - also included:

(Top)3 inch stack of C3 Posi Shims from 1-1/2 kits, Carrier Shims, Pinion Shims $60 value (Mid) GM pattern paste, 8 ARP Ring Gear Bolts, 3 Diff Seals (Bottom) Pinion Lower Bearing Press Tool, Slip-Fit used Pinion "Set-up" Bearings, Slip-Fit carrier bearing shells for bearing pressing, Ring Gear install screw-in studs

So the first taker gets the use of the disposable shims & seals!

Some other items you will need to do this at home:
Dial indicator & stand
Torque wrenches
Impact gun
Brass drifts 1/4, 3/8"
Brass, Deadblow hammer
Vise
12 Ton Harbor Freight Shop Press or better
Engine Stand

3rd Pic - Hand Tools Not Included

Other required hand tools, not for sale

So whether you want to just replace some leaky seals, change your ring gear, or polish & tune your posi to beef it up, it is do-able at home.
Adding ARP bolts and cap screws is the least you can do, apparently some of those come loose!
I am a rookie at this, but GTR1999 coached me and said my results were at least respectable.

I will be offering some of my left over diff parts for sale in another thread.

this is a terrific idea, i hope to do a rebuild as soon as i can find a rebuildable case w/ a posi and hope these tools are still available then. thanks leigh1322!

 

If anybody needs the tools shoot me a PM, I can box them up and get a shipping quote.
I'll have to dig through the spare parts to see what I have to forward with the tools, probably most of what Leigh sent me is still in the box.

 

Tools and spare parts are enroute to member tfringo for his gear swap.

 

I would like to be added to the list to use the tools, is anyone in line after tfringo?

Is this program still available? I'd like to get in line if so. Great idea.

 

I would recommend private messaging the last 2 guys in the list
tfringo
or rv8driver

 

I never heard from anyone regarding the tools. I ended up buying a rebuilt diff.
