Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off, and the wheels are cool to the touch.

2. Tire Balance Adjustment

Remove the wheels from the vehicle using a lug wrench.
Mount the tires on the tire balancer.
Spin the tires and note any imbalance; add weights to balance the tires as necessary.
Reinstall the wheels and torque lug nuts to manufacturer specifications (typically 80-100 ft-lbs).

3. Wheel Alignment

Place the vehicle on an alignment rack.
Adjust the camber, caster, and toe settings according to manufacturer specifications.
Confirm that all settings fall within acceptable ranges.
Test drive the vehicle to ensure the alignment correction resolved any pulling issues.

4. Suspension Inspection

Visually inspect all suspension components for signs of wear, such as cracked bushings or leaking shocks.
Replace any components that show signs of damage.
Tighten any loose bolts or nuts to manufacturer specifications.
