If you have a very loud grinding or humming sound coming from the front end, and your brakes and tires are fine, your car may be in need of wheel hub repair. Fortunately, this repair can be done in your garage, given you have the correct tools to perform the job. You can also save yourself hundreds of dollars performing the job yourself.

The tools required to perform wheel hub repair are as follows;

  • Socket set
  • Ratchet
  • Pneumatic impact gun
  • Axle socket
  • Bearing Press
  • Screwdrivers
  • Cut-off tool
  • Ball joint separator

The bearing press is an optional tool, as it is not common to see this in your garage at home. Instead of having your own bearing press, you can simply take the hub to a shop and they will press it out for $15.00 to $25.00. So don't run out and buy a several hundred dollar bearing press if you don't have one.

The process of removing the hub and replacing it can be difficult without the proper step-by-step directions. This article is going to provide you with the steps to remove and replace the wheel hub in most vehicles.

  • First, remove the vehicles wheels
  • Then, loosen and remove the brake caliper
  • Next, loosen and remove the brake caliper bracket
  • Pull the brake rotor from the hub
  • Remove the cotter pin from the axle nut and remove the axle nut
  • Remove the bolts holding the upper and lower ball joint
  • Use a ball joint separator to loosen the ball joints from the hub
  • Lightly tap the CV axle until it falls from inside the hub
  • Use the bearing press to separate the hub and spindle
  • Use the cut-off tool to carefully cut the bearing off of the spindle
  • Check the spindle for any damage and replace if needed
  • Grease the new bearing and press it into the old hub
  • Press the new or old spindle back into the hub
  • Place the axle back in the hub assembly making certain the spines are properly lined up
  • Re-insert the ball joints into the hub and tighten them down to proper torque
  • Insert brand new cotter pins into each ball joint
  • Re-install the axle nut with a brand new cotter pin
  • Place rotor back on the hub

When performing this repair, there are several tips to follow to save major headaches in the long run. These tips are;

  • Alignment: Make certain to have the vehicle aligned since you disassemble main components of the front end. This will prevent the vehicle from pulling or wearing the tires after the service is performed.
  • Replace bad parts: If you notice any other bad parts like; ball joints, tie rod ends and bushings, and replace them while the vehicle is apart so you do not have to do this same work over again.

Now that you have the basic knowledge needed for wheel hub repair, it is time to get started repairing your vehicle.
