How To Replace Wheel Bearings

From mysterious hums to wobbly rides, there are telltale signs that your bearings are throwing a serious tantrum.

What Are Wheel Bearings, Anyway? 

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 wheel 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. 
 

Here’s What You’ll Need: 

• Jack stands
• Jack
• Hammer
• Screwdriver
• Socket set 3/8
• 3/8 Ratchet
• Wood Block
• Cleaning Brush
• Torque Wrench
• Pliers
• Wheel Bearing & Races
• Wheel Bearing Grease
• Cotter Pin
• Cleaning Solvent

Words of Wisdom From The King: ​

• Every vehicle is different. Always follow the owner’s manual when it comes to maintenance and repairs.
• 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

1. Raise and support the vehicle securely on jack stands. See our previous DIY: How to Jack Up a Vehicle Safely for more information. 
2. Spin each wheel and check for any noise or resistance.
3. 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 wheel bearings should be replaced.
4. Remove the tire.
5. Remove the brake caliper and hang it securely out of the way with wire. Never let the caliper hang by the brake hose.
6. Remove the dust cap. If a screwdriver won't work, try using a chisel and hammer.
7. Remove the cotter pin from the middle of the spindle nut. Throw the cotter pin away; always use a new cotter pin during installation.
8. Remove the spindle nut and washer.
9. Remove the outer wheel bearing.
10. Pull the hub/disc assembly off the spindle.
11. Remove the seal from the rear of the hub assembly using a screw driver or seal removal tool.
12. Remove the inner wheel bearing from the hub assembly.
13. Remove the old bearing races using a press.
14. Clean the inside of the hub with solvent and a brush to remove all dirt and grease.
