That is rough cost of the diff.

Do you wanna replace gears too? Plus fluid, why not do bearings while you are at it, plus labor.....

Im 90% sure this is the tru trac for our trucks

This is a helical gear Limited slip Diff, different then lockers, and clutch types. Gadget Approved mod on the URD truck:top:

You have to drain rear, take the wheeles, brakes, axles off. Then drive shaft, then the third member comes out.

what was his reasoning for saying auburn was best?

you dont have to fully remove the brakes or the wheels when i put the spool in my 90 pick up i just unbolted the backing plate fron the housing undid the brake lines and the ebrake cables and pulled them out about 3-4" and unbolted the driveshaft to pull the third. for the next steps its best to get your hands on a copy of the fsm and follow the steps to rnr the differentail but only as far as replacing the the ring gear. then throw it back in the truck and button everything up

Technically you maybe right but IMO it would be some much easier to just get the wheels outta the way.


*Im not sure if you will have to re shim anything. At least pay attention to where the stock shims are and put them back in the same spot.

i see so there are shims somewhere in the rear end. i shouldve paid more attention in my auto tech class but ill do some research and see if i can pull out a repair manual with pix in it....thanks for the help guys ill update this post once i get everything in the truck

FWIW I have heard a bunch of s10 guys say bad stuff about auburn.

They are cheap (price and quality), not rebuild-able (eaton posi's you can replace the clutches), and they wear out fast.

Just do your own research and find what will work best for what you are trying to do with it.
