How To Replace A Wheel Bearing And Hub Assembly
Have you been hearing squeaks and chirps as you drive down the road? Unfortunately, it’s probably not the winged migration of the Canada Geese. Chances are the strange noises coming from your wheels are faulty bearings.
Wheel bearings play two important roles in your car’s suspension:
- Bearings allow the wheels to rotate with little friction.
- Bearings support a car’s weight.
As your car gets older, it’s imperative to keep an eye (and ear) on these often overlooked parts.
If it’s time for your bearings to be replaced, why not do the job yourself? We’ve got the tools and tips you need to install new bearings on your wheels in no time.
Parts you'll need:
- Jack stands
- Screw driver
- Socket set 3/8
- 3/8 Ratchet
- Wood Block
- Cleaning Brush
- Torque Wrench
- Wheel Bearing & Races
- Wheel Bearing Grease
- Cotter Pin
- Cleaning Solvent
Safety comes first
Every vehicle is different. When it comes to maintenance and repairs, always follow the vehicle's owner's manual.
Safety should be your number one priority. Don't smoke, drink alcoholic beverages, or wear a necktie while working on the car. Watch out for hot objects, sharp instruments, hazardous materials and other potential safety hazards in and around your workspace.
Don't work with a Philips when the job calls for a flat. Substituting tools can compromise your safety or your vehicle's performance.
Finally, when the fun turns to frustration, or if the job requires specialized knowledge beyond your capabilities, please do not attempt it yourself. Talk to a professional mechanic or installer.
Steps for removing old bearings
- Raise & support the vehicle securely on jack stands.
- Spin each wheel and check for any noise or resistance.
- Move the wheel in and out by grabbing the tire with one hand on the top of the tire and the other hand on the bottom. If there is any movement, the bearings should be replaced.
- Remove the tire.
- Remove the brake caliper and hang it securely out of the way with wire. Never let the caliper hang by the brake hose.
- Remove the dust cap. If a screw driver won't work, try using a chisel and hammer.
- Remove the cotter pin from the middle of the spindle nut. Throw the cotter pin away; always use a new cotter pin during installation.
- Remove the spindle nut and washer.
- Remove the outer wheel bearing.
- Pull the hub/disc assembly off the spindle.
- Remove the seal from the rear of the hub assembly using a screw driver or seal removal tool.
- Remove the inner wheel bearing from the hub assembly.
- Remove the old bearing races using a press.
- Clean the inside of the hub with solvent and a brush to remove all dirt and grease.
