How to Replace the Front Wheel Bearing in a Chevy Avalanche


The Chevrolet Avalanche uses a sealed front wheel bearing assembly that's integrated into the hub. This means the bearings can't be serviced; they need to be replaced with the hub as an entire assembly. Fortunately, this is not a very difficult task, and you can do it with a few basic tools. In this case, the project vehicle is a 2005 Chevrolet Avalanche, but the process is similar for other years of Chevrolet Avalanche.

Things You'll Need

  • Jack
  • Jack stands
  • Tire iron
  • Mechanic's wire
  • 3/8-inch ratchet and socket set
  • Red thread-locking compound
  • Torque wrench
  • Replacement wheel hub/bearing assembly
  • Set the head of the jack underneath the front cross member of the frame. Lift up the jack and put the jack stands underneath the frame. Remove the wheels using a tire iron.

  • Use the ratchet to unbolt the brake caliper from the steering knuckle and then lift it off the rotor. Support the caliper by the mechanic's wire on the frame, so that the caliper is not hanging by the brake line. Slide the rotor off the hub, using both hands.

  • Unplug the wire leading into the hub assembly using your hands. Then unbolt the hub from the back side of the steering knuckle, using the 3/8-inch ratchet and socket. Pull the hub off the knuckle and set it aside.

  • Place a drop of the red thread-locking sealant onto the threads of the hub bolts. Bolt the replacement hub onto the steering knuckle using the ratchet. Then torque the bolts down to 133 ft-lbs. using the torque wrench. Slide the rotor onto the hub and reinstall the brake caliper with the ratchet. Reconnect the wiring to the hub.

  • Reinstall the wheels and lower the car off the jack stands with the jack.
