Solution

1. Preparation

Tools required: Jack, jack stands, lug wrench, tire pressure gauge, alignment tools, wheel balancer.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery if working on suspension components.

2. Inspect and Replace Tires (if necessary)

Remove the wheel covers or hubcaps, if applicable.
Loosen lug nuts slightly while the wheel is still on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheels by completely unscrewing the lug nuts.
Inspect the tires for uneven wear patterns, bulges, or punctures.
Replace tires if any defects are found or if tread depth is below legal limits.

3. Perform Wheel Alignment

Mount the vehicle on an alignment rack.
Use alignment tools to measure and adjust the camber, toe, and caster angles according to manufacturer specifications.
Recheck the alignment after adjustments to ensure it is within acceptable parameters.

4. Balance Wheels

Mount the wheels onto a wheel balancer.
Spin the wheels to identify any imbalances.
Add wheel weights as necessary to ensure proper balance.
Reinstall the balanced wheels onto the vehicle and secure with lug nuts.

5. Recheck Suspension Components

Visually inspect control arms, bushings, tie rods, and ball joints for damage or excessive wear.
Replace any worn or damaged components with OEM or high-quality aftermarket parts.
Reassemble any components removed during inspection.
