How to Install a Hub Bearing Assembly

Replacing a hub bearing assembly can be a more economical method of replacing a worn out wheel bearing. Your savings will come from eliminating the cost of paying for a machine to press the bearings into place. Instead of this more expensive method of replacing bearings in your wheel, you simply purchase the hub bearing assembly and install it yourself. You'll need only a few standard tools and a set of good installation instructions.

Things you'll need:

  • Car jack
  • Lug wrench
  • Jack stand
  • Wheel chock
  • Drive breaking bar
  • Socket wrench set
  • Spindle nut socket
  • Half-Inch drive ratchet
  • Large flat-edge screwdriver
  • Sandpaper
  • Bungee cord
  • Rubber mallet
  • Slide hammer
  • C-Clamp
  • Adjustable torque wrench

Step 1 – Prepare Your Vehicle

To safely work on your vehicle, park it on a level surface such as your garage floor. To keep your vehicle from rolling while you work on it, apply your park brake, place the vehicle in gear, and put chocks under the wheels. On the wheel on which you'll be replacing the hub bearing assembly, use a lug wrench and loosen the lug nuts. Don't remove them yet, or your wheel will likely come off before you're ready to remove it.

Step 2 – Raise Your Vehicle off the Floor

Place your car jack under your car in a position where it will raise the wheel you'll be working on. Raise the car and slip a jack stand under the frame and near the wheel. Now, finish taking off the lug nuts and remove the wheel.

Step 3 – Remove the Caliper, Rotor, and ABS Wires

Find the bolts that hold the caliper in place. Tie a bungee cord around the caliper to keep it from falling when you remove the bolts that keep it in place. If it falls, you will risk having it sever the brake hose it is connected to. Use a socket wrench to loosen and remove the caliper bolts. Pry the caliper loose, using a large, flat-head screwdriver. If your vehicle uses caliper bridge bolts, try removing them with your socket wrench. If you're unable to break these bolts loose, use a break bar to break them loose. Should your brake pads be connected in the bridge, you should be able to pry them loose using your screwdriver. Remember the position they are in prior to removal. You'll need to replace them in this same position. Next, remove the rotor. From where the ABS wires are attached to the hub bearing assembly, unclip these wires.

Step 4 – Remove Wheel Bearing Assembly Bolts

Locate the bolts that attach the wheel bearing assembly. Use a socket wrench to remove them. If necessary, use the breaking bar. Now, connect the slide hammer onto the lug studs and tighten the lug nets to secure it. Remove corrosion from the knuckle by using sandpaper.

Step 5 – Install the Bearing

Connect the new bearing to the knuckle, pushing it on as far as you can get it. Attach wheel bearing assembly bolts. Put the washer and spindle nut in place and tighten the nut. Replace brakes, ABS lines, and the wheel.
