The other side gear has zero play.
Now the questions:
-is this bad? (my guess is yes)
-can this be fixed with a sleeve / do I need a new diff?
I'm pretty out of my comfort zone here, I don't really know what's normal. Once I know what it's supposed to be I could maybe fix it? Or find a replacement?

I just don't know whether I have perfectly normal backlash in all directions, or a worn sidegear, carrier, spider? And I really don't want to tear it apart if there's nothing wrong with it | | | | | Joined: May 2001 Posts: 7,438 Extreme Gabster | | Extreme Gabster Joined: May 2001 Posts: 7,438 | Thrust washers are optional (as required) on the spider gears. The manual for the HO-33 gives a max. freeplay figure. | | |
