Wheel Stud / Lug Nut: Service and Repair
Subsequent installation of wheel-bolt lock
Loosen wheel bolts.
Lift car until wheel can be turned.
Loosen wheel bolts enough for it to be easy to move wheel on wheel hub.
Turn wheel so that valve is face down.
Remove upper wheel bolt and insert wheel-bolt lock.
Possible play in wheel centre 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.
For tightening torque, refer to Technical Data
Should a customer complain about wheel imbalance after installation of wheel-bolt lock, wheels will have to be finish-balanced.
