leaking driver side axle seal...AGAIN!

[dgrinnell]

Alright guys I have a 2012 cc silverado that has a rc level kit and 25k mile on it. I had the Trans case rebuilt in dec. Due to a bad pinion bearing. All warranty work. Since then I have had 3 axle seal done on the drivers side all warranty again done by the dealer now this on is leaking. Any ideas on what's causing this? Going to call the dealer Monday to get it back in but this is getting frustrating.

Yup.

 

The surface that the seal rides on is the machined part of the axle shaft. If that's worn or damaged at all, it won't seal, so replacing the shaft is the obvious second step. I've never had to replace one on a front diff, but I've never had a repeated comeback with that problem.

 

Inside the housing is the bearing that supports the axle shaft; if that's worn it allows the shaft too much play, and again the seal keeps leaking. I'd probably replace the seal, axle shaft and bearing together - they pretty much work as a set. I've had to do that more than once on rear axles, where a quick seal replacement has come back leaking again.

the left frt axle shaft on 2500s can be a real PITA and there is several ways to get the PITA shafts out ,,,,

 

up north we used to remove and split the case ,move the pin to the vent area and beat the piss out of the shaft 'till it popped out ,,,

 

back down in southern Alberta we lost the knuckle and hooked up a sliding hammer to the shaft and using a 5/8" heater hose around the handle just reef on the hose and the handle moves really fast to the end of the shaft and eventually the shaft pops out

 

1/2 tons are easy ,,,just them GD 2500s lol
