Today i ordered the spindle (2 of them) for the rear end of the Jetta... ordered from ID parts.com. I already have the Rear Wheel Bearing kit with hub... The locking nut that goes down over the spindle when all is installed is included. (#16, and #17 in the diagram below)
Rear Wheel Stub Axle - ID parts.com (#11 in the diagram)
Rear Brake set - ID parts.com
DOT4 Brake Fluid - ID parts.com
I decided to redo the brakes and rotors because when i was teaching at a high school recently the shop said they could do them for me.... They used NAPA parts (sorry napa) and they were complete junk. I also think that the squeaking of the brakes might have something to do with the rear bearing going bad. Anyway you slice it, i think it is relatively inexpensive insurance on the back end of the car. When i have it all torn apart i will make an assessment of the rear caliper pin sets. According to ID parts, these tend to rust and cause problems. They are pretty expensive to buy them and not have to use them.
I already have the rear axle bushing set for the car (#27 in the diagram), but just realized i probably should get the bolt set (#24 in the diagram) as well
