Jack car up and leave it up with both wheels in air.
Remove wheels and spacers
Use a light steel brush and clean around the hub and mating surface very good
Make sure spacer is clean and free of debris
Place spacer back over hub (if you have the alignment posts those help)
Replace wheel and insert all lugs
Tighten lugs in a star pattern as tight as you can while still in air
Lower car until wheels just meet the ground (don't drop car down)
Finish torquing to 95 +/- ft. lbs in a star pattern again
Lower car the rest of the way and test drive
If you still get vibration, you may have slung a wheel weight off? The stick on weights can come off.
