I replaced the lip seal and the O-ring on the shaft this weekend. That wasn't too bad. What sucked was getting the roll pin back in. Then it took me a bit how to figure out how to refill the final drive (a long rubber hose and drilling a hole in the bottom of the bottle to let air in as the fluid left the top did the trick, after I spilled a bunch of it). I did not put a sleeve on my flange, as it did not have any pitting or scratches in it (I mean, it had super light surface scratches, but nothing that seems like it would warrant sleeving).
But it still leaks. There doesn't appear to be any oil above or within the diff adjustment nut (as in, where the flange and lip seal are), but it's collecting on the "key" that locks the nut in place. I would take a picture, but the leak never seems to show up on camera. I'm thinking that it's seeping from the bottom edge of the nut onto the key. My Delorean Go kit included the O-ring for the diff adjustment nut, so I plan on trying to replace that this weekend. I understand that it is highly recommended to never touch that nut, so this should be interesting.
I'm curious, though: This is a very minor seep, so would turning the nut a couple of notches fix it? Assuming it doesn't screw up the diff, that is. Dave T's
post in another thread suggests I should not do that...
Thanks!
