Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a level surface and securely lifted using jack stands.
Wear safety gloves and goggles.

2. Tire Inspection and Replacement

Sub-steps:
1. Remove the wheel by loosening lug nuts using a socket set.
2. Inspect the tire for bulges, punctures, or uneven wear.
3. Replace the tire if damaged, ensuring it matches OEM specifications (size, type).
4. Reinstall the wheel and torque the lug nuts to the manufacturer's specifications (usually around 90-100 ft-lbs).

3. Suspension Component Replacement

Sub-steps:
1. Remove the necessary wheel to access the suspension.
2. Visually inspect struts and shocks for leaks or damage.
3. If worn, remove the strut/shock assembly by detaching it from the upper mount and lower control arm.
4. Replace with new OEM or equivalent parts, ensuring proper alignment of mounting holes.
5. Reattach the assembly and torque fasteners to manufacturer specifications.

4. Wheel Bearing Inspection and Replacement

Sub-steps:
1. With the wheel removed, check for any play in the wheel bearing by wiggling the wheel.
2. If play is detected, remove the hub assembly to access the bearing.
3. Replace the bearing with a new one, lubricating it according to specifications.
4. Reassemble the hub and wheel, ensuring all fasteners are torqued correctly.
