Prevent Loose Wheel Retaining Bolts

When securing the road wheel retaining bolts to the correct torque, the bolts can loosen during vehicle use. The reason identified for this problem is corrosion between the disc and hub mounting faces. This results in a clearance that reduces the wheel bolt torque even when the bolts are secured correctly.


Importance of Proper Wheel Bearing Adjustment

Premature bearing failure will impact a fleet’s efficiency with serious performance, safety and budgetary implications. Proper wheel bearing adjustment is a key factor for optimal bearing life. To reduce premature bearing failure in heavy duty wheel-end applications, the ideal bearing end-play setting should be between 0.001” and 0.005”.
