Installation Notes and Tips

Verify rear axle configuration and ring gear size before ordering. Confirm the vehicle application against the fitment list for your exact year, make, and model. Differential service typically requires careful setup of bearing preload, backlash, and seal placement, so follow factory service procedures during installation.
