Loosen wheel bolts.
Lift car until wheel can be turned.

Possible play in wheel center and wheel weight could cause imbalance.
This imbalance is reduced to a minimum by installing the somewhat heavier wheel-bolt lock in the top wheel-bolt position.
Tighten wheel bolts crosswise and by hand in this position (wheel-bolt lock at top, valve at bottom).
Lower car and tighten wheel bolts crosswise.
Wheel Bolts 120 +/- 10 Nm
Should a customer complain about wheel imbalance after installation of wheel-bolt lock, wheels will have to be finish-balanced.
