i am replacing my front rotors. when i took my rotors i was cleaning up my bearings to regrease them and i noticed that they feel kinda loose. is this normal at all? also the washer on the front is missing the key peice for the spindle, is this gonna affect anything too much, if so where can i buy a new one?

The rollers are normally somewhat loose in the cage. Inspect them for metal flakes, pitting, scoring or discoloration. Inspect the races as well. The outer bearing is most susceptible to failure.

I'd replace the big washer. Look in the "HELP" section at your auto parts store, or ask the counterman. Failing that, try a wrecking yard or your GM dealer. They used that same washer on about eleventybillion cars.
