  • Noise during acceleration, turning, or load transfer at the rear axle

Installation Notes and Tips

Confirm rear left position, spline count, axle length, and axle nut thread size before installation. Verify ABS configuration and tone ring requirements against the vehicle’s original axle setup, especially on Ford Explorer and Mercury Mountaineer applications. Inspect related seals, hub components, and mounting points during replacement to help prevent repeat driveline noise or leakage.
