- Install New Bearings: Apply grease to the new bearings and insert them into the hub.
- Reassemble the Hub: Place the hub back onto the axle and secure it with the castle nut and cotter pin.
- Connect the Brakes: Reinstall the dust cap or retaining clips and reconnect the brake wire.
- Lubricate: Apply grease to the zerk fitting or grease point on the hub.
- Reinstall the Wheel: Place the wheel back onto the axle and tighten the lug nuts. Use a torque wrench to ensure proper tightness.
Common Mistakes to Avoid
- Overtightening Bearings: Excessive torque can damage bearings and lead to premature failure.
- Using the Wrong Grease: Always use a grease specifically designed for wheel bearings.
- Ignoring Seal Damage: Worn or damaged seals will allow contamination to enter the bearings.
