Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Tire Inspection and Replacement

Tools Required: Tire pressure gauge, jack, jack stands, lug wrench
Check tire pressure; inflate to manufacturer's specifications if low.
Inspect tires for uneven wear; replace if necessary.
If replacement is needed, jack up the vehicle and secure it with jack stands.
Remove the wheel using a lug wrench, replace with a new tire, and torque lug nuts to manufacturer specifications (typically 80-100 ft-lbs).

3. Suspension Component Inspection and Replacement

Tools Required: Socket set, torque wrench, pry bar
Inspect shocks and struts for leaks or damage. Replace if necessary.
Check bushings for cracks or wear; replace if damaged.
If components are worn, remove the affected part using a socket set, install the new part, and torque to manufacturer specifications.

4. Alignment Adjustment

Tools Required: Alignment tool (or take to a professional)
After replacing tires and suspension components, perform a wheel alignment.
Adjust the alignment settings to manufacturer specifications, focusing on toe-in and camber angles.

5. Steering System Inspection and Repair

Tools Required: Socket set, torque wrench
Inspect tie rods and ball joints for play. Replace any damaged components.
Tighten or replace components as necessary, ensuring all hardware is torqued to specifications.
