The vehicle’s wheel bearings are crucial in ensuring smooth and efficient wheel rotation. However, over time these bearings may wear out, leading to issues such as noise, vibration and compromised safety. That said, changing wheel bearings is a manageable task that can save money on professional repairs. Let’s explore the step-by-step process of changing your wheel bearings.
Steps to Change a Car’s Wheel Bearing
Here are some simple steps to replace wheel bearings and get them spinning smoothly again.
Materials Needed
- Jack and jack stands
- Lug wrench
- Socket set
- Screwdrivers
- Pliers
- Wheel bearing grease
- New wheel bearings
- New cotter pin
- Hammer
- Bearing race and seal driver set (optional but recommended)
Step 1: Safety First
Before you start the car, ensure the vehicle is parked on a flat surface and engage the parking brake. Safety should be a top priority. It is recommended to wear appropriate personal protective equipment such as gloves and safety glasses.
Step 2: Lift the Vehicle
Use the jack to lift the vehicle off the ground and secure it with jack stands. Make sure to lift the car high enough to provide sufficient clearance for working on the wheel. Here is how you can safely use a car jack
Step 3: Remove the Wheel
Use the lug wrench to loosen and remove the lug nuts from the wheel. Once removed, take the wheel off and set it aside.
Step 4: Locate the Wheel Bearings
Identify the location of the wheel bearings on your vehicle. Typically, they are situated within the hub assembly. If your vehicle has a drum brake system, you’ll need to remove the drum to access the wheel bearings. Moreover, if you’re unsure about the type of brakes equipped in your vehicle, distinguishing between drum and disc brakes is essential. Here’s a straightforward guide to help you identify them.
Step 5: Remove the Hub Assembly
Use the socket set to remove the bolts securing the hub assembly to the steering knuckle or axle. Carefully detach the hub assembly from the vehicle, exposing the wheel bearings.
Step 6: Remove the Old Bearings
Once the hub assembly is removed, take out the old wheel bearings. Depending on your vehicle, you may need pliers to remove the cotter pin and castle nut securing the bearings. Now, carefully slide the old bearings off the spindle.
Step 7: Inspect and Clean
Inspect the spindle and hub assembly for any signs of damage. Clean the components thoroughly, removing any old grease or debris. Inspect the races for wear and if necessary, use a bearing race and seal driver set to install new races.
Step 8: Grease the New Bearings
Apply wheel bearing grease to the new bearings. Ensure that the bearings are evenly coated with grease to promote smooth operation.
Step 9: Install the New Bearings
Slide the greased bearings onto the spindle and secure them with the castle nut. Tighten the nut until snug, then back it off slightly to align the cotter pinhole. Insert a new cotter pin through the hole and bend it to secure the nut.
Step 10: Reassemble the Hub Assembly
Reattach the hub assembly to the steering knuckle or axle bearings using the socket set. Now, tighten the bolts securely.
Step 11: Put the Wheel Back On
Place the wheel back onto the vehicle and hand-tighten the lug nuts. Lower the vehicle to the ground using the jack and then tighten the lug nuts in a crisscross pattern with the lug wrench.
Step 12: Test Drive
Once you assemble, it is important to test drive your car to ensure that the new wheel bearings function properly. Listen for any unusual noises and pay attention to the overall performance of the wheels.
