About two weeks ago I bolted on some nice 22s. They were balanced by a good shop, had good tires put them, alignment, but I still had a pretty bad vibration. After re-torqueing the lugs with no change, I was about to start over with the tire balance when decided to check the wheel to hub fit. I found that I could get a 0.015 feeler gage between the two about half way around. That equaled about 0.135” of variation at the tread (about the thickness of two pennys).
The problem was the little spring clips that are over one or two of the lug studs from the factory. The clips are used to hold the break rotor on during assembly at the factory, but don’t do much once the car is built. The way my rims are built, there is little or no counter sinking of the stud holes on the hub side and were not mating properly with the hub face. I removed the clips and the vibration went away.
Thought I would pass it along.
