The wheel bearings are what allow a vehicle's wheels to roll freely. If the bearings become corroded or damaged your van can come to a grinding halt, literally. If your Voyager model is later than 1995, the bearings themselves can't be replaced or maintained, but rather the entire hub must be replaced. If you have a 1995 or earlier model that has some excessive bearing wear, you should replace all of the wheel bearings at the same time.
Place the vehicle on jack stands or a frame lift that allows free movement of the wheels. Do not engage the parking break.
Remove the lug nuts from the wheels with the lug wrench. Pull the wheel toward you off of the lug bolts and set it aside.
Rotate the rear brake drum. If there is roughness, wobbliness or resistance the bearing should be replaced.
Pry the grease cap from the centre of the brake drum using a hammer and chisel, tapping around the edges until you are able to pull it off. Pull the cottar pin, located under the grease cap with a set of pliers.
Remove the nut locking piece and the large bearing adjusting nut. It should be the only nut under the grease cap. Remove the large washer and outer bearing by hand.
Remove the break drum from the spindle by pulling it toward you.
Pull out the grease seal from the back side of the brake drum using a seal puller. Thoroughly clean out the grease from inside the drum as well as the hub that the drum was attached to.
Pack the new bearings with the high temperature multipurpose EP grease, taking care to put grease in the hub cavity and between all the rollers in the bearing unit.
Put the new bearing unit in the hub by hand and reseal it using a seal pressing tool.
Put the brake drum back on in the same order.
Tighten the adjusting nut with the torque wrench to 23 foot-pounds while spinning the brake drum. Turn the nut backward again 90 degrees and then re-tighten it by hand.
Place the nut lock mechanism back in place lining up one pair of the slots with the cottar pin hole and sliding in the new cottar pin.
Clean the grease cap and push it back into place. Use the hammer to make sure it goes in all the way
Put the wheel back on the lug bolts and tighten the lug nuts to 95 foot-pounds using the torque wrench. Tighten the lugs in a criss-cross sequence so that the wheel fits snugly against the hub.
