No spacer on spindle? Help!

[tomt]

I've been upgrading my bralkes (rebuild calipers, SS lines, cooling, pads, etc), and I'm having a problem with my right front hub/spindle.

I removed the hub to install the blocking blate and the colling thing, and reinstalled the hub without much difficulty (it was a little tough to pull off after the outer bearing was removed).

After getting the hub back on, and hoping I got the bearings just right, I thought all was well.

After reinstalling the newly rebuilt caliper, I found that the inner edge of the caliper was rubbing on the inside edge of the rotor (on the leftside the caliper is nicely centered within the caliper opening).

So... I took the thing off again. I noticed that there was only a little O-ring against the end of the spindle. On the left side, there was another piece that the hole in the cooling duct fit around nicely -- not so on the right.

A pitcure of my spindle (a little fuzzy) and the diagram for the part *I THINK* I am missing is attached.

I've never had the hub off before... could I have been running without the spacer and not had horrible problems??

I looked everywhere under the car and couldn't find the missing part. Could it have somehow seated itself inside the hub??

Please help brake and hub experts!!

Hey, I just remembered that when I had new S03's put on a few weeks ago 2 of the lugs were frozen and had to be drilled off (by another shop, not the tire guys).

In the process the studs were destroyed and they had to remove the right front rotor to get the studs out.

They must have lost my spacer! I've probably driven the car 5 times since then (never hard), and there is a scratch on the inside rotor (from the caliper I assume. It's pretty minor, so I think I'm OK there).

Does this make any sense? Could I have even driven the car once without the spacer?
