ISSUE:
The use of air impact tools to tighten wheel lug nuts can lead to overtightened and/or unevenly tightened wheel lug nuts. Air impact tools typically used
for wheel lug nut removal and installation can generate up to 475 N.m (350 lb-ft) of torque. Overtightened and/or unevenly torqued wheel lug nuts may
cause:

^

Brake vibration

^

Distortion of the wheel hub

^

Distortion of the brake rotor
