Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Safety glasses and gloves should be worn during the repair.

2. Tire Pressure Adjustment

Tools Required: Tire pressure gauge, air compressor
Check and adjust tire pressures to the recommended PSI as indicated on the driver’s side door jamb.

3. Tire Rotation or Replacement

Tools Required: Jack, jack stands, lug wrench
If uneven tire wear is observed, rotate the tires according to the manufacturer’s recommended pattern or replace worn tires.
Tighten lug nuts to the specified torque (usually around 140 ft-lbs for GMC trucks).

4. Wheel Alignment

Tools Required: Alignment machine (typically available at service centers)
Bring the vehicle to a qualified alignment shop or use an alignment tool to adjust the camber, caster, and toe angles to factory specifications.
Follow manufacturer specifications for alignment settings.

5. Suspension Inspection and Repair

Tools Required: Socket set, torque wrench, possibly replacement components
If damaged suspension components are identified, replace them (e.g., control arms, tie rods).
Ensure all fasteners are torqued to the manufacturer's specifications.
