Solution

1. Preparation

Gather tools and parts needed for repairs.
Ensure the vehicle is parked on a flat surface and the engine is off.
Safety: Engage the parking brake and wear safety glasses.

2. Tire Inspection and Replacement (if necessary)

Remove the hubcaps or wheel covers (if applicable).
Loosen the lug nuts using a lug wrench.
Jack up the vehicle and secure it with jack stands.
Remove the tires and inspect for uneven wear or damage.
Replace tires if tread depth is below manufacturer's recommendations (typically 2/32” or less).

3. Suspension Component Inspection and Replacement

Visually inspect struts and shocks for leaks or damage.
Use a socket set to remove the strut assembly if replacement is necessary.
Replace struts or shocks with OEM or equivalent parts, ensuring proper fitment.
Torque the strut mounting bolts to the manufacturer's specifications.

4. Wheel Alignment Adjustment

After suspensions repairs, use an alignment machine or take the vehicle to a professional for an alignment.
Adjust camber, caster, and toe settings to meet manufacturer specifications.
