Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Gather safety gear including gloves and goggles.

2. Tire Inspection and Replacement (if necessary)

Inspect Tires: Check for proper inflation and any signs of uneven wear.
Replace Tires: If tire wear is uneven or tread is worn out, replace with new tires.
- Remove wheel covers or hubcaps (if applicable).
- Loosen lug nuts and lift the vehicle using a jack.
- Remove lug nuts and take off the tire; install the new tire and replace lug nuts, torquing to manufacturer specifications (typically 80-100 ft-lbs).

3. Shock Absorber/Strut Inspection and Replacement

Inspect Shock Absorbers: Look for oil leaks or signs of physical damage.
Replace Shock Absorbers: If damaged, replace with new, quality parts.
- Remove the wheel to access the shock absorber.
- Unbolt the upper and lower mounts of the shock absorber, using a socket set.
- Install the new shock absorber, ensuring all bolts are torqued to the specified value.
- Reinstall the wheel and lower the vehicle.

4. Suspension Component Inspection and Replacement

Inspect Suspension Components: Look for worn bushings, control arms, or springs.
Replace Worn Components: If any parts are found to be damaged during inspection, replace them.
- Remove necessary components to access the damaged part (may require removing the wheel).
- Use a wrench to unbolt and remove the damaged component.
- Install the new component and ensure all bolts are torqued to specifications.

5. Wheel Alignment

Perform Alignment: After any repair, have the vehicle's alignment checked and adjusted as necessary.
- Take the vehicle to a professional alignment shop for adjustment.

Tools Required:

Jack and jack stands
