CanadaWheel Hub Bearing Replacement
Responsible for keeping the wheel attached to the vehicle, the hub assembly is a crucial part of the steering system. When it comes to installing a new hub assembly, getting the job done right the first time is critical for reducing customer comebacks and ensuring the safe operation of the vehicle. Follow these instructions for installing a wheel hub assembly to ensure optimum steering and handling.
Getting Ready
Once you have your safety equipment, be sure that you have the proper tools. you'll need:
- Axle nut socket
- Torque wrench
- Pry bar
- CV axle to hub adapter removal tool (depending on application)
Removing the Old Hub Assembly
Step 1
Raise the vehicle off the ground and properly support it, then remove the lug nuts and wheel.
Step 2
Remove the axle nut using an axle nut socket; socket size can range from 30mm to 36mm. Note – Using an impact wrench is not recommended. Tip: Loosen the axle nut with the tire on the ground, using a CV axle to hub adapter removal tool, press the axle out of the bearing; never use a hammer to remove the axle.
Step 3
Remove and support the brake caliper. Make certain it is positioned so that it won’t interfere with the installation process. Inspect the brake pads.
Step 4
Remove the brake rotor.
Step 5
Remove the hub bolts from the steering knuckle.
Step 6
Using a pry bar between the module and knuckle, carefully separate the module from the knuckle.
Step 7
Remove any burrs or loose metal from the knuckle (bearing housing) to provide proper alignment when the hub is being seated. Inspect the splines on the CV shaft for damage.
Installing the New Hub Assembly
Step 1
Guide the new module onto the CV shaft and into the knuckle. Align carefully or premature failure may result. Before completing the installation, attach the ABS connector (if equipped) and check with the key on to ensure the vehicle is reading a correct signal from the sensor.
Step 2
Torque the hub mounting bolts (steering knuckle to module flange) to manufacturer’s specifications using the appropriate torque wrench.
Step 3
Reassemble the brake rotor and caliper
Step 4
Replace the old axle nut with a new one. If no special instructions are noted in the OE service procedure, torque the axle nut to manufacturer’s specifications with the vehicle raised and the hub assembly unloaded. Do NOT use an impact wrench.
Step 5
Replace the tire/wheel on the vehicle. Lower the vehicle to the ground and torque the lug nuts to specification using a torque wrench.
