Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the vehicle is in "Park" mode.

2. Inspect and Adjust Tire Pressure

Tools Required: Tire pressure gauge, air compressor
Check each tire's pressure with a gauge and inflate to the recommended PSI as stated in the owner's manual.
Recheck the pressure after inflating to ensure accuracy.

3. Wheel Alignment

Tools Required: Alignment machine or laser alignment tool, socket set
If misalignment is detected, perform a four-wheel alignment:
- Adjust toe, camber, and caster angles to manufacturer specifications.
- Tighten all bolts to the specified torque values found in the service manual.

4. Inspect and Replace Suspension Components

Tools Required: Socket set, wrenches, pry bar
Check all suspension components for wear and damage.
If any components (bushings, ball joints, control arms) show signs of wear, replace them as follows:
- Lift the vehicle and remove the wheel.
- Unbolt the damaged component and replace it with a new part.
- Torque all bolts to manufacturer specifications.

5. Rotate Tires

Tools Required: Jack, jack stands, lug wrench
Rotate tires according to the recommended tire rotation pattern for your vehicle.
Ensure lug nuts are properly torqued after rotation.
