When to use pre adjusted wheel bearing adjustment?
Pre-AdjustedWheel Bearing Adjustment Procedures The goal of this recommended procedure is to achieve a verifiable wheel bearing end play of 0.001” to 0.005” (.025 mm to .127 mm). This procedure applies to steer, drive and trailer axle assemblies using conventional double nut or single nut systems on Class 6, 7 and 8 trucks.
