Solution

1. Tire Inspection

Remove the front tires using a socket set.
Inspect tire tread for uneven wear; replace tires if they are excessively worn or damaged.

2. Wheel Alignment

Tools Required: Alignment machine or string alignment tools.
Measure the camber, caster, and toe angles using the alignment machine.
Adjust the toe angle to the manufacturer's specified range; typically, the front toe should be set to 0.1° to 0.2° toe-in.
Tighten and secure all adjustment bolts to the specified torque settings (usually around 50-70 ft-lbs).

3. Suspension Component Inspection

Tools Required: Jack, jack stands, socket set, torque wrench.
Raise the vehicle using a jack and secure it on jack stands.
Inspect control arms and bushings for cracks or play; replace if necessary.
Check ball joints and tie rod ends for excessive movement; replace if play is detected.

4. Brake Inspection (if applicable)

Inspect brake calipers for sticking; ensure they retract fully.
Clean or replace any components that show signs of dragging or heat damage.
