Wheel Bearing replacement

These don't have to be a nightmare...

Wheel Bearing replacement

Loosen the wheel nuts and jack up the trailer so the wheel clears the ground. Chock the trailer for safety’s sake with axle stands, never put your full trust in your jack.

Remove the wheel nuts and wheel, and use a soft-faced hammer to gently tap the dust cap off. Locate and remove the split pin from the castle nut. Remove the castle nut and washer, grab the hub and pull off the axle.

Remove the seal and seal retaining washer. The bearing is made up of two parts – the cone with its tapered rollers and the cup which supports the cone.

Before going any further with your work, clean the cones and slide them onto their respective positions on the axle. If the bearing slides on the axle sloppily and does not sit firmly, the axle could be worn and need replacing. Contact your trailer repairer if this is the case, and ask about options to change the axle.

Remove the seal wear ring from the back of the hub with a screwdriver and clean out the inside of the hub with solvent and clean rags.

To remove the cups from the hub, tap out from the opposite ends with a pin punch and hammer taking care not to damage the bore of the hub. Once the bearing cups have been removed, clean and check hub for damage. Fit the new cups with a brass or mild steel drift and hammer, never hit any bearing part with a hammer or hardened steel as the bearing being very hard, can crack and cause bodily harm when it shatters.

Pack the new cones thoroughly with grease and place a good quantity of grease in the hub cavity. Fit the back end bearing, tap on the seal wear ring and before sliding the hub onto the axle, fit the seal retaining ring and seal to the axle.

Slide hub firmly onto the axle and fit the front end bearing cone. Fit the washer and castle nut. Tighten the castle nut until a slight binding is felt. Back off until the hub runs free but without any free play. Fit new split pin through the castle nut and axle, smear a gob of grease around the inside of the dust cap and tap onto the hub.

If you are unsure and don't think you can do this. I can do these for you very easily and at your own home .

Good advice mate,If there's one thing boaties should learn to do themselves is replacing wheel bearings and having the necessary spares/tools to do roadside repairs if need be.I can assure you if you get caught out on a cold dark night miles away from help you'll be kicking yourself.

I will also add... you have to pack the bearing inside and out.. NOT just smear grease around the bearing and cup
