Why a Fresh Wheel Bearing Matters
When a rear wheel bearing begins to fail, the vehicle can develop a humming noise, uneven tire wear, or even a sudden loss of steering control. Replacing the bearing and hub assembly restores smooth rotation, protects the axle, and keeps the suspension geometry intact. For owners of the Chevy Equinox, a timely replacement can prevent more costly damage to the drivetrain.
Getting the Job Started
The first step is to lift the vehicle and secure it on jack stands. Remove the right rear wheel by loosening the five 19‑mm lug nuts with a breaker bar. Once the wheel is off, locate the two caliper bracket bolts on the knuckle. These bolts are recessed and both measure 18 mm. Keep a hand on the bracket while you remove the last bolt to prevent it from falling.
Use a caliper hanger to support the brake caliper and slide it off the rotor. If the rotor is stuck, a rubber mallet can help break the seal. With the caliper removed, you can access the axle nut, which requires a 32‑mm socket and an impact wrench for removal.
Extracting the Bearing and Hub
Before pulling the bearing, tap the axle shaft with a hammer along the center divot to confirm it moves freely inside the hub. This check ensures the shaft is not seized. Next, locate the three 18‑mm bolts that hold the wheel bearing and hub assembly. Hold the assembly with one hand to keep it from falling, then push the axle shaft in while pulling the bearing out. The bearing should slide out cleanly once the axle is fully seated.
Remove the backing plate that sits behind the bearing. This plate protects the inner race and should be replaced with a new one during reassembly. Keep the backing plate aside until the new bearing is ready to install.
Preparing and Installing New Components
Clean the mating surfaces with brake cleaner and a wire brush. For stubborn grime, a razor blade can scrape away residue. After wiping down, apply a light coat of lubricant to the axle splines and the hub-to-knuckle interface. This lubrication reduces friction during reassembly and helps the new bearing seat properly.
Slide the new backing plate over the axle first, aligning the cutout with the brake caliper and bracket. Then push the new wheel bearing and hub assembly into place. If the backing plate shifts slightly, realign it before tightening the three 18‑mm bolts. Hand‑thread the bolts first, then tighten them to 74 ft‑lb using a torque wrench.
Reinstalling the Wheel and Final Checks
Reattach the axle nut by hand, then snug it with an impact gun. Use a pry bar between the two studs to lock the axle, allowing you to torque the nut to 185 ft‑lb. Remove the pry bar and reinstall the wheel. Hand‑tighten the five 19‑mm lug nuts in a criss‑cross pattern, then finish with a torque of 100 ft‑lb.
Reinstall the brake rotor by sliding it onto the hub, aligning the set‑screw hole with the rotor’s holes. Hand‑tighten the set screw with a T30 Torx bit, then snug it down. Reattach the brake caliper and bracket, ensuring the caliper hanger is secure. Double‑check all torque values before lowering the vehicle.
Testing the Repair
After lowering the car, give the wheel a quick spin to confirm smooth rotation. A road test will reveal whether the noise has been eliminated and the steering feels stable. If everything runs smoothly, the replacement is complete.
Final Thoughts
Replacing a rear wheel bearing and hub on a Chevy Equinox is a manageable task for a seasoned DIY mechanic. By following the steps above—careful removal, thorough cleaning, precise torqueing, and diligent reassembly—you can restore reliable performance and extend the life of your vehicle’s suspension components.
