Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if electrical components will be inspected or if performing suspension work.

2. Tire Pressure Adjustment

Use a tire pressure gauge to measure the pressure in each tire.
Inflate or deflate tires to meet the manufacturer's specifications (usually found on a sticker inside the driver's side door).
Recheck tire pressure after inflation.

3. Tire Inspection and Replacement

Examine all tires for bulges, cracks, or uneven wear.
If any tires are damaged or excessively worn, replace them with new ones.
Ensure that the new tires are balanced properly during installation.

4. Wheel Balancing

Remove the wheel and tire assemblies from the vehicle using a socket set.
Mount the wheels on a tire balancing machine and check for imbalances.
Add wheel weights as needed to achieve balance, then reinstall the wheels.

5. Suspension Inspection and Repair

Visually inspect all suspension components for cracks, excessive play, or damage.
If control arms, bushings, or shocks show wear, replace them with OEM or high-quality aftermarket parts.
Reassemble any disassembled components and torque bolts to manufacturer specifications.

6. Wheel Alignment

Use a wheel alignment machine to check the alignment angles (camber, caster, toe).
Adjust the alignment as necessary to meet the manufacturer's specifications.
