Step-by-Step Guide
1. Remove the Lug Nuts
Using a lug wrench, loosen the lug nuts on the rear wheel where you suspect the faulty bearing. Do not remove them completely at this point.
2. Jack Up the Vehicle
Place a jack under the designated jack point near the rear wheel. Slowly raise the vehicle until there is approximately 6 inches of clearance between the ground and the tire. Secure the vehicle with jack stands.
3. Remove the Lug Nuts and Wheel
Completely remove the lug nuts and pull the wheel straight towards you to detach it from the hub.
4. Remove the Brake Caliper
Locate the brake caliper and use a 17mm socket to remove the two bolts holding it in place. Carefully lift the caliper off the rotor and suspend it with a bungee cord or wire. Do not let it hang by the brake hose.
5. Remove the Rotor
Use a hammer and a pry bar to gently tap the rotor loose from the hub. Once it’s loose, slide it off.
6. Remove the Old Wheel Bearing
Locate the wheel bearing in the center of the hub. Use a 32mm socket to remove the large nut holding it in place. Once the nut is removed, use a pry bar to carefully pry the old wheel bearing out of the hub.
7. Install the New Wheel Bearing
Clean the hub surface where the new wheel bearing will sit. Apply a thin layer of grease to the new bearing and carefully press it into place. Use a hammer and a socket to tap the new bearing flush with the hub surface.
8. Install the Nut
Thread the large nut onto the wheel bearing and tighten it using a 32mm socket. Torque the nut to the manufacturer’s specifications.
9. Install the Rotor
Slide the rotor back onto the hub and tap it into place using a hammer.
10. Install the Brake Caliper
Position the brake caliper over the rotor and secure it with the two bolts. Torque the bolts to the manufacturer’s specifications.
11. Install the Wheel
Lift the wheel and align it with the hub. Thread the lug nuts onto the studs and tighten them using a lug wrench.
12. Lower the Vehicle
Slowly lower the vehicle from the jack stands.
13. Final Tightening
Use a torque wrench to tighten the lug nuts to the manufacturer’s specifications.
14. Road Test
Take your Toyota Yaris for a short drive to ensure everything is working correctly. Listen for any unusual noises or vibrations.
Wrapping Up
Replacing a rear wheel bearing on a Toyota Yaris is not a complex task, but it requires precision and attention to detail. By following these steps carefully and using the right tools, you can save yourself a significant amount of money on repair costs.
