Detailed Description

Installation Notes and Tips

Verify the vehicle year, make, model, and position before ordering. Match the bore diameter, outside diameter, and seal width to the original seal specification, and confirm whether the application is front or front inner. Clean the sealing surface thoroughly and inspect the axle shaft and hub area for wear, scoring, or corrosion before installation.
