Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Obtain a jack and jack stands for safety.

2. Tire Inspection and Replacement

Inspect Tire Pressure:
- Use a tire pressure gauge to check and adjust tire pressures to manufacturer specifications.
Examine Tire Tread:
- Look for uneven wear; if found, consider rotating or replacing tires.
- If tread depth is below 2/32 of an inch, replace tires.
Replace Tires (if necessary):
- Lift the vehicle using a jack and secure with jack stands.
- Remove the lug nuts using a socket set and replace worn tires with new ones.
- Tighten the lug nuts to the manufacturer’s torque specification (usually around 80-100 ft-lbs).

3. Suspension Inspection and Repair

Visual Inspection:
- Check for worn or damaged bushings, ball joints, and struts.
Replace Worn Components:
- If any suspension parts are damaged, use a wrench to remove them and install new ones.
- Ensure all bolts are torqued to manufacturer specifications.

4. Wheel Alignment

Perform Alignment:
- Take the vehicle to a professional alignment shop.
- Follow their procedures for a four-wheel alignment to ensure proper handling.
