Improved Performance	Smoother operation, reduced wear on components
Extended Trailer Life	Prolonged lifespan, minimized maintenance costs

How to Replace Bearings on Trailers

Materials:

New bearings and races

Bearing grease

Bearing puller

Hammer

Chisel

Steps:

Safety First: Park the trailer on a stable, level surface and engage the parking brake. Use wheel chocks to prevent any movement.

Remove the Wheel: Unfasten the lug nuts and carefully remove the wheel.

Extract the Hub: Use a bearing puller to detach the hub from the axle.

Remove Old Bearings: Tap the old bearings out of the hub using a chisel and hammer.

Inspect Hub and Axle: Clean and inspect the hub and axle surfaces for any damage. Replace if necessary.
