Common Issues This Bearing Can Address

• Excessive bearing noise from the transmission or axle assembly

Installation Notes and Tips

Verify cone bore, cone length, and cone radius before installation to confirm the bearing matches the original specification. Clean and inspect the shaft, race, and surrounding components for scoring, pitting, or contamination before assembly. Use proper bearing installation practices to avoid damaging the crowned raceways or rollers. Confirm the vehicle position listed in the fitment data, such as front outer, outer, rear, or right, before ordering.
