Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the 12V battery to prevent any electrical issues while working on the vehicle.

2. Tire Pressure Check

Use a tire pressure gauge to measure the pressure of each tire.
Inflate or deflate tires to the correct pressure as specified in the owner’s manual.

3. Wheel Alignment

Lift the vehicle using a hydraulic lift or jack stands.
Remove the front wheels using a socket set.
Adjust the camber and toe settings on the alignment machine to match manufacturer specifications. Usually, the toe should be set to 0.05 degrees outwards.

4. Suspension Inspection

Visually inspect tie rods, ball joints, and control arms for signs of wear or damage.
If any components are worn, replace them with OEM parts as necessary:
- Tie rods: Check for play in the joints.
- Ball joints: Ensure they are not cracked or excessively worn.
- Control arms: Inspect bushings for deterioration.

5. Reassembly

Reinstall the front wheels and torque them to the manufacturer’s specifications (typically 100-110 ft-lbs).
Reconnect the 12V battery.
Lower the vehicle back to the ground.
