Step-by-Step Guide to Wheel Bearing Replacement on Trailer

Remove the Wheel: Use a socket wrench to loosen the lug nuts and remove the wheel.

Disconnect the Brakes: Unplug the brake wire connector and remove any dust caps or retaining clips.

Remove the Hub: Remove the cotter pin and castle nut that secures the hub. Use a puller or a hammer and chisel to detach the hub from the axle.

Inspect and Clean: Thoroughly inspect the bearings, races, and seals for damage. Clean the hub and axle using a degreaser.

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.

Mixing Old and New Bearings: Always replace all bearings on a single wheel.
