Should there be lube in the drive shaft area? I somehow had the impression that the drive shaft assembly was "dry", unlike the BMW assembly. Or is this a seal issue. I'm going to replace seals, but hope to NOT crack the assembly open.
And what's that little finned reservoir doing under the unit? I can't find it listed in the tavola ....
What should I be checking for?
As mtiberio says, no seals on the pinion shaft. Gear oil finds it's way up past them to (hopefully) lube the spliny bits. Still a good idea to grease the splines liberally during assembly and once in a while afterwards.
Bloodweiser has given you some very good advice. Charley Cole will reshim and reseal the rear drive, thus ensuring that it won't leak and will live a long life. Not at all expensive for what you get (piece of mind). http://www.zydecoracing.com
The "little finned reservoir" is a sump of sorts, #37 in the drawing above.
