Solution

1. Preparation

Tools Required: Jack, jack stands, tire pressure gauge, alignment machine, basic hand tools (wrench set, socket set).
Safely park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery if working on electronic components.

2. Check and Adjust Tire Pressure

Remove valve caps and use a tire pressure gauge to check each tire.
Inflate or deflate tires to the recommended pressure (found in the owner’s manual or on the driver’s door jamb).

3. Perform Wheel Alignment

Tools Required: Alignment machine.
Position the vehicle on an alignment rack.
Follow the machine's instructions to adjust the camber, caster, and toe angles as needed to align the vehicle to manufacturer specifications.

4. Inspect and Replace Worn Suspension Components

Lift the vehicle using a jack and secure it with jack stands.
Visually inspect struts, shocks, and bushings for any signs of wear or damage.
If worn, remove the damaged components:
- Struts: Unbolt the top and bottom mounts, and replace with new struts.
- Bushings: Use a bushing press to remove and install new bushings.
Torque all bolts to manufacturer specifications.

5. Rotate Tires

Remove the tires and rotate them according to the recommended pattern (e.g., front to back, side to side).
Reinstall the tires and torque the lug nuts to the specified settings.
