H3 Front diff seal
While I was changing the oil in my H3 alpha I noticed the driver's side diff seal was starting to tear leak. Looking for feedback if someone has tried to do it themselves. Are special tools needed? I am an advanced amateur garage mechanic but looking for guidance. It is way out of warranty.Thanks for looking in my thread.

If you have an Alpha it must be an 08 or newer. So you have a 5 year / 100,000 mile drivetrain warranty. If under 100K then the dealer will fix it for you. Your For Ssle post in Dec of 20111 said you only had 62K????
If you are over 100K, you will need to remove the rim/tire, remove the half-shaft (threads on here on how to go about all of this), R&R the seal, install the half-shaft using the "blue seal protector" (sold at dealers), then do everything backwards.
Nothing tricky or "special" tools needed. You may have to go buy the correct large socket for the 1/2 shaft retainer nut (I use a 1 3/8" others use a 35 or 36mm).

Really, 100k? I was under the impression it was a 50K mile warranty. I have been lucky and only took my H3 in for service to have the torsion bars turned to level it out. I guess I will be calling the dealer?
