Installation Notes and Tips

Verify bore diameter, outside diameter, and seal width before installation to confirm proper seating in the steering gear housing. Inspect the shaft surface for scoring, corrosion, or wear that could affect sealing performance. Clean the sealing bore thoroughly and install the seal squarely to avoid distortion of the metal case or sealing lip. Confirm the steering gear is properly lubricated after service and check for leaks during reassembly.
