Lighter = Faster (N/A build thread #2)

Replaced the front wheel bearings and races yesterday since I had play in the driver's side. I heated the hubs in the oven and rapidly cooled the outer races with ice water get them out. I ended up re-using the seals though. The new seals put too much pressure on the hub to get an accurate measurement of the bearing pre-load (followed FSM procedure). Unfortunately, I'm still getting play on the driver's side. I'd go as far as saying it isn't improved. I even went out today and torque the hub nut to 22 ft-lb and STILL had play. I didn't see anything else moving so I'm left with the assumption the spindle itself is worn out. Does that even happen on these cars? I guess I'll try to find a used one and replace it before DGRR.
