Check
- Check lug bolts for wear.
Result
» Spots (> 30%) of the bearing surface (1) of the taper on the screw head show silvery wear.
Measure
- Replace lug bolts.
Parts: Lug bolts
NOTE: Never use an impact screwdriver or electric screwdriver to apply and tighten the lug bolts.
The rim must rest evenly against the brake disc.
In the case of non-original BMW lug bolts/wheel rims, it may be necessary to retighten the lug bolts on user account of setting properties (refer to the documentation from the manufacturer).
Do not apply oil to new lug bolts. - Replace the corroded lug bolts (arrows).
Parts: Lug bolts
