Title: GM rear axle questions
Post by: Admin on February 10, 2009, 08:51:27 PM: Ok, im not an expert at everything, only most things.... ;D If i was My name would be Masterfabr...

Anyhow my pinion seal is leaking on my van rear axle, can i just unbolt the yoke and replace the seal? Gm lash is set with the pinion yoke and washers correct? as long as i put it back the same way, will i be good?

You tow with that thing and if there is wear in the pinion bearings it may be needing a complete overhaul (cheering you up yet?? ;D )

Have to jack the rear end up so the tires are off the ground (no load from it being in park) and see if you have any side play in the pinion shaft yoke area.

Also how much backlash does it have?

The bearings are separated by a "crush sleeve" that doesn't crush.You can't over torque the nut as far as the bearings are concerned.
