Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check the pressure.
Inflate or deflate tires to the manufacturer's recommended pressure (typically found on the driver's door jamb).

3. Wheel Alignment

Tools Required: Alignment machine, jack, jack stands
Position the vehicle on the alignment rack.
Follow the machine's instructions to adjust the toe, camber, and caster settings according to manufacturer specifications.
Tighten all adjustment bolts to specified torque values (usually around 70-80 ft-lbs).

4. Suspension Inspection and Repair

Tools Required: Socket set, torque wrench, pry bar
Raise the front of the vehicle and secure it with jack stands.
Inspect each suspension component for play or damage:
- Check control arms for cracks or excessive wear.
- Test ball joints by attempting to move them with a pry bar.
- Examine tie rod ends for looseness.
Replace any worn or damaged components.
Reassemble and torque suspension components to manufacturer specifications.
