Eaton says not to use stock bearings but i can not find what ones to use.

 

It probably fits the 8.5" and 8.6" diff, very common when it comes to aftermarket lockers and limited slips for these rear ends. Give randys ring & pinion a call or similar shop specializing in diff parts and gears and they can get you hooked up.

 

There you go. It' stupid... I know... I dealt with it too with my trutrac and locker in my Blazer.

 

Yep. This.

 

Dang thats awsome, thank you.
Where did you order your bearings from?

 

Summit used to have this with the trutracs ad but I guess not now. I ordered bearings at Napa.
