Solution

1. Preparation

Gather tools and parts as listed below.
Park the vehicle on a flat surface, engage the parking brake, and wear safety gear.
Disconnect the battery to ensure safety during repairs.

2. Brake Inspection and Repair

Sub-step 1: Remove the rear wheel using a socket set.
Sub-step 2: Inspect brake pads for wear; if pads are worn below the minimum thickness (usually 3mm), replace them.
Sub-step 3: Check the brake rotor for scoring or warping; if damaged, resurface or replace the rotor.
Sub-step 4: Apply brake grease to the back of the new brake pads and install them correctly, ensuring they seat properly.
Sub-step 5: Reinstall the wheel and torque the lug nuts to 76 lb-ft.

3. Wheel Bearing Replacement (if necessary)

Sub-step 1: After removing the wheel, remove the brake caliper and rotor.
Sub-step 2: Remove the hub assembly retaining nut using a socket wrench.
Sub-step 3: Using a bearing puller, carefully remove the old wheel bearing from the hub.
Sub-step 4: Clean the hub assembly and install the new wheel bearing, ensuring it is pressed evenly.
Sub-step 5: Reassemble the hub, rotor, and caliper, torqueing all components to the manufacturer's specifications.

4. Suspension Component Inspection (if necessary)

Sub-step 1: Check the rear shock absorbers for leaking or damage; replace if necessary.
Sub-step 2: Inspect control arms and bushings for wear and replace if they show signs of cracking or excessive play.
Sub-step 3: Reinstall all components securely and check alignment if any suspension parts were replaced.
