Replacing a wheel bearing can be a challenging task, but it’s definitely doable with the right tools and a little bit of patience. In this comprehensive guide, we’ll walk you through the step-by-step process of how to change the rear wheel bearing on a Mercedes Vito.
Tools and Materials You’ll Need
Before you begin, gather the following tools and materials:
- New rear wheel bearing
- Socket wrench set
- Torque wrench
- Axle stand
- Jack
- Wheel chocks
- Safety glasses
- Gloves
- Rags
Safety First
Before you start working on your Vito, park it on a level surface and engage the parking brake. Place wheel chocks behind the front wheels to prevent the vehicle from rolling. Wear safety glasses and gloves to protect yourself from any potential hazards.
Step 1: Remove the Wheel
Use the socket wrench to loosen the lug nuts on the rear wheel that needs the bearing replaced. Do not remove the lug nuts completely at this point. Use a jack to lift the rear of the Vito and place an axle stand under the frame for support. Carefully remove the lug nuts and take off the wheel.
Step 2: Remove the Brake Caliper
Locate the brake caliper on the rear wheel assembly. Use the socket wrench to remove the bolts that hold the caliper in place. Carefully lift the caliper off the rotor and secure it out of the way using a bungee cord or wire.
Step 3: Remove the Rotor
Use the socket wrench to remove the bolts that hold the rotor to the wheel hub. Once the bolts are removed, carefully pull the rotor straight off the hub.
Step 4: Remove the Axle Nut
Locate the axle nut in the center of the wheel hub. Use the socket wrench to loosen the axle nut, but do not remove it completely at this point.
Step 5: Remove the Wheel Hub
Use a hammer to gently tap around the circumference of the wheel hub until it loosens from the axle. Once the hub is loose, carefully pull it straight off the axle.
Step 6: Remove the Old Wheel Bearing
The old wheel bearing will be pressed into the wheel hub. Use a bearing puller to carefully remove the old bearing from the hub. Be careful not to damage the hub or the bearing during this process.
Step 7: Install the New Wheel Bearing
Press the new wheel bearing into the wheel hub using a bearing press. Make sure the bearing is seated properly and is flush with the surface of the hub.
Step 8: Reinstall the Wheel Hub
Carefully slide the wheel hub back onto the axle. Thread on the axle nut and tighten it to the manufacturer’s specified torque using a torque wrench.
Step 9: Reinstall the Rotor
Place the rotor back onto the wheel hub and secure it with the bolts. Tighten the bolts to the manufacturer’s specified torque using a torque wrench.
Step 10: Reinstall the Brake Caliper
Lift the brake caliper back onto the rotor and secure it with the bolts. Tighten the bolts to the manufacturer’s specified torque using a torque wrench.
Step 11: Reinstall the Wheel
Place the wheel back onto the wheel hub and tighten the lug nuts by hand. Lower the Vito and fully tighten the lug nuts to the manufacturer’s specified torque using a torque wrench.
Step 12: Test Drive
Once the wheel is reinstalled, take your Vito for a test drive to ensure that the new wheel bearing is working properly. Listen for any unusual noises or vibrations. If everything seems fine, you’re all set!
