All I had time to do last night was swap the left front and rear tires. The front had a small weight on the inside - none on the outside. The rear had a larger weight on the outside - none on the inside. Maybe the shop was running low on weights?
Anyway, the car still had the vibration - it's only slight, but compared to none at all before, unacceptable. My appt for rebalance is tomorrow night, and I'm going to insist they let me see what the machine says about weight placement. Even a static balance would be better than improper axial weight placement.
If this doesn't solve it, I'll have to shell out more bucks on a Hunter balancing elsewhere, I guess.
