Try pinwall's eBay store for a less than $200 final drive, either get a new flange from HDL or
perhaps pinwall has a good flange too...

HDL has the thrust washer too, and VRCC sponsor
www.carolinabikeandtrike.com has
O-ring sets...
I posted these ideas on lube on another thread:
There's a lot of information, and misinformation, out there... I'm about to replace my driveline, and
here's what I think at this point...
Per the manual:
moly paste on final drive splines.
moly grease at the pinion cup end (wheel end) of the drive shaft.
regular grease at the universal end of the drive shaft.
Internet Knowledge I think is good:
Don't glop tons of grease into the pinion cup, it'll clog up the holes which are there to allow
gear oil to circulate through the pinion cup. Oil isn't lost from the final drive, the seal at the
pinion cup prevents that. The two holes in the pinion cup are different, one is made so that
oil flows into the pinion cup, the other facilitates it flowing back into the final drive.
Internet Knowledge I think is bad:
pack lots of heavy grease into the pinion cup, make sure you clog the holes (?)
I don't have a grease-scale

but the manual says how much grease to
put on each end:
pack 0.5 grams of grease onto the [universal joint] splines.
pack 2 grams of molybdenum disulfide grease into the pinion joint [pinion cup] spline.
