Solution

1. Preparation

Gather necessary tools and parts, ensuring safety equipment is available.
Park the vehicle on a flat, level surface and engage the parking brake.
Disconnect the battery if electrical components will be handled.

2. Tire Pressure Adjustment

Tools Required: Tire pressure gauge, air compressor
Check and adjust tire pressures to manufacturer specifications found on the driver’s door jamb.

3. Wheel Balancing

Tools Required: Wheel balancing machine
Remove the wheel and tire assembly from each corner of the vehicle.
Mount the tire on the balancing machine and spin it to identify heavy spots.
Add wheel weights to balance the tire, then re-mount the tire on the vehicle.

4. Wheel Alignment

Tools Required: Alignment rack
Lift the vehicle using a hydraulic lift.
Adjust the alignment angles (camber, caster, toe) according to manufacturer specifications.
Ensure all adjustments are torque to the specified values.

5. Suspension Inspection and Repair

Tools Required: Socket set, torque wrench, jack stands
Inspect suspension components for wear or damage, such as control arms, tie rods, and bushings.
Replace any worn or damaged components with OEM or high-quality aftermarket parts.
Re-torque any bolts to the manufacturer’s specifications.
