Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a secure lift or jack stands.
Disconnect the negative battery terminal for safety.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Carefully remove the wheel from the hub.

3. Remove Brake Components

Remove the caliper by unscrewing the bolts and hanging it safely.
Remove the brake rotor by sliding it off the hub.

4. Inspect and Replace Wheel Bearings

If the hub is not a sealed unit, remove the hub assembly by unscrewing the retaining nut and any bolts securing it.
Clean the area and inspect the inner and outer bearings for damage or wear.
If damaged, replace the bearings with new ones, making sure to pack them with high-quality wheel bearing grease.
Reassemble the hub, ensuring all components are torqued to manufacturer specifications (typically around 150-200 ft-lbs for the hub nut).

5. Reassemble Brake Components

Reinstall the brake rotor and caliper.
Ensure that all bolts are torqued according to specifications.

6. Reinstall Wheel and Test Drive

Reattach the wheel and lug nuts, tightening them in a crisscross pattern.
Lower the vehicle and reconnect the negative battery terminal.
Test drive the vehicle to ensure the issue is resolved.
