Common Mistakes to Avoid

When performing wheel bearing replacement on trailer, there are several common mistakes to avoid:

Mistake	Consequence
Incorrect bearing preload	Premature bearing failure
Overtightening axle nut	Damage to bearing and axle

Not replacing seals	Contamination of bearings

Getting Started with Wheel Bearing Replacement on Trailer

Step 1: Gather Tools and Materials

Jack and jack stands

Socket wrench set

Torque wrench

Grease gun

New wheel bearings, seals, and cotter pins

Step 2: Safety First

Park the trailer on a level surface and engage the parking brake.

Place wheel chocks behind the wheels opposite the one being serviced.

Step 3: Remove the Wheel

Use a jack to raise the trailer and support it on jack stands.

Remove the lug nuts and wheel.

Step 4: Remove the Hub

Depending on the trailer, you may need to remove the brake drum or rotor to access the hub.

Use a socket wrench to remove the hub bolts and carefully pull off the hub.

Step-by-Step Approach

Step 5: Inspect Bearings and Seals

Inspect the old bearings for any signs of wear, damage, or pitting.

Replace both bearings and seals, even if only one appears damaged.

Step 6: Lubricate and Install Bearings

Apply a generous amount of high-temperature grease to the new bearings.

Insert the bearings into the hub and align them with the axle.

Step 7: Install Hub and Torque

Place the hub back onto the axle and tighten the bolts to the specified torque.

Ensure that the cotter pin is properly installed.

Step 8: Reinstall Wheel

Mount the wheel onto the hub and tighten the lug nuts.

Torque the lug nuts to the manufacturer's specifications.
