How do you change front wheel bearings on a 1996 Honda 400 Foreman 4x4?

Hub needs to come off (two ball joints, steering arm, brake pipe and breather hoses).

Clamp in a vice and take out the seal from the inside of the hub (centre of brake pads). Remove the circlip, then place face down on the floor and use a suitably sized socket and mallet to knock out the bearing.

Installation is the same procedure in reverse. Remember to put back the circlip, and the split pins (cotter pins) back into the crown nuts for the steering arm, the ball joints and your hub nuts.

Bleed brakes, and you're done. A few hours work if your quad is in reasonable nick, and you have the parts to hand.

It's a good opportunity to replace brake pads and ball joints while you've got the hubs off.
