Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Safety warning: Wear safety glasses and gloves.

2. Check and Adjust Tire Pressure

Using a tire pressure gauge, check the pressure of all tires.
Inflate or deflate each tire to match the recommended pressure found in the owner’s manual or on the driver’s side door jamb.

3. Wheel Alignment

Tools Required: Alignment tool, jack, jack stands, torque wrench.
Elevate the vehicle using a jack and secure it on jack stands.
Set up the wheel alignment tool according to the manufacturer’s instructions.
Adjust the toe, camber, and caster angles to factory specifications using the alignment settings provided in the service manual.
Tighten all bolts to the specified torque values.

4. Inspect and Replace Suspension Components

Visually inspect all suspension components for signs of wear or damage.
Replace any worn-out components, such as bushings or ball joints.
Tools Required: Socket set, wrenches, pry bar.
Use a pry bar to relieve tension and remove the damaged component.
Install the new part and torque to manufacturer specifications.

5. Rotate Tires

Tools Required: Jack, jack stands, lug wrench.
Lift the vehicle and remove the tires.
Swap the front tires with the rear tires and vice versa (cross rotation may be necessary for certain tread patterns).
Reinstall the lug nuts and tighten them to the manufacturer's torque specifications.
