I need to change a wheel seal in an '03 Tahoe. I've pulled side gears before, but haven't been able to figure out how to get them out of this half-assed limited slip.
Tried youtube, but only found pictures of busted stuff....any help?

remove the S shaped spring between the axles, get a helper to push in on the outboard end of the axle. and use needle nose pliers to remove the C clip.

Take your time, and don't drop anything into the diff.

on pavement turn the wheel hard right and stomp the throttle till the transmission upshifts into second.

I have one in my DMax with over 800lbs of torque and it hasnt given me any troubles with 38 inch tires, how much more stress do you put thru yours?

i dont own one but the violent action of it locking would seem to be what breaks it, not how much torque you are putting to it

FWIW: I figured out how to get it apart; after pulling the center pin (same with a standard diff) I put a come-a-long on the end of the axle and applied a minimal amount of pull which moved the axle in enough to use a magnet to remove the C-clip, re-assembly was the same.....all very easy once the puzzle was figured out.
