Solution

1. Preparation

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

2. Check Tire Pressure

Tools Required: Tire pressure gauge
Use the tire pressure gauge to check the pressure in each tire.
Inflate or deflate tires to match the manufacturer's specifications as indicated on the driver's side door jamb.

3. Alignment Adjustment

Tools Required: Wheel alignment machine, socket set
Lift the vehicle using a jack and secure it on jack stands.
Remove any wheel covers or lug nut covers.
Adjust the front and rear alignment angles (camber, caster, toe) according to the manufacturer's specifications using the alignment machine.

4. Inspect and Replace Suspension Components (if necessary)

Tools Required: Socket set, wrench set, torque wrench
Inspect control arms, bushings, struts, and shocks for wear.
If any components are damaged, replace with OEM or quality aftermarket parts.
Reassemble and torque components to the manufacturer's specifications.
