How to Change the Wheel Bearings on Motorcycles
Wheel bearings are some of the most durable parts of a motorcycle — but when they fail, it's dangerous for you and your bike. If your bearings are starting to show signs of wear, a quick replacement can get you back on the road quickly. Not comfortable with a DIY repair?

Remove the Wheel and Set Up a Work Area
Once you've determined which wheel has bad bearings, remove it from the bike. Clear off a worktable and rest the wheel on two blocks of wood; this creates a stable, supportive surface that protects the rim and rotor. Depending on the design of the bike, you might also need to remove the sprocket carrier.
Remove the Seals
Insert a flathead screwdriver into the center of the wheel seal and use gentle pressure to pry it out of the hub. Flip the wheel and remove the opposite seal. If your seals are stuck, try heating the hub with a torch for 15-30 seconds. If your bike has circlips under the seals, use pliers to pull them out carefully.
Drive Out the Bearing and Spacers
Insert a drift into the center of the wheel, and position it, so the edge catches on the inner ring of the bearing. Tap the end of the drift with a hammer to loosen the bearing. Continue around the inner edge until the bearing and spacer fall out. Flip the wheel and repeat with the opposite side. If your bearing refuses to budge, use a torch to heat the wheel hub; the heat can help release the bearing.
Clean the Bearing Seats
Spray a clean cloth with contact cleaner. Insert the cloth into the hub and use it to wipe away any residue from the hub and the bearing race. Add a layer of grease to the outer edges of the new bearings.
Install the New Bearings
Heat the hub, and place the new wheel bearing into the hole. Tap gently around the edges with a hammer to get the bearing into place, making sure it's sitting evenly. Place a bearing driver over the bearing, insert the driver handle, and tap on it with a hammer until the new bearing is flush with the face of the wheel. The tool delivers the force to the outer race, ensuring that it slides in squarely.
Flip the wheel over, drop in the spacer, and install the second wheel bearing following the same procedure. Make sure the spacer is lined up with the inner races. Press the wheel seals back into place.
