Solution

1. Preparation

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

2. Adjust Tire Pressure

Tools Required: Tire pressure gauge, air compressor.
Check and adjust each tire to the recommended PSI found in the owner’s manual or door jamb sticker.

3. Wheel Alignment Adjustment

Tools Required: Wheel alignment machine, alignment shims, wrenches.
Position the vehicle on the alignment rack and attach the alignment sensors.
Adjust camber, caster, and toe settings to meet manufacturer specifications.
- Camber: Typically between -0.5° to 0.5° (consult specifications)
- Toe: Usually between 0° to +0.2° (consult specifications)
Tighten all control arm and tie rod bolts to the specified torque values.

4. Inspect and Replace Worn Suspension Components

Tools Required: Socket set, wrench set, jack and jack stands.
Check bushings, ball joints, and tie rods for play or damage.
If any components are worn, replace them using the following steps:
- Raise the vehicle and support it securely with jack stands.
- Remove the wheel to access the suspension components.
- Use the socket set to remove and replace damaged parts.
- Reassemble and tighten all fasteners to the specified torque.

5. Rotate Tires

Tools Required: Lug wrench, jack, jack stands.
Rotate the tires according to the manufacturer’s recommended pattern to promote even wear.
Ensure wheels are properly torqued upon reinstallation.
