Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to prevent electrical issues during repairs.

2. Inspect and Replace Tires

Tools Required: Tire iron, jack, jack stands, torque wrench.
Remove the wheel covers if applicable.
Loosen the lug nuts while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheels and inspect for damage or uneven wear.
Balance tires if necessary, or replace them if they are worn out.
Reinstall the wheels and torque the lug nuts to the manufacturer's specifications.

3. Inspect Suspension Components

Tools Required: Socket set, pry bar, torque wrench.
Visually inspect control arms, ball joints, and bushings for signs of wear.
Use a pry bar to check for play in the suspension components.
Replace any worn or damaged components, ensuring proper torque specifications are followed during reassembly.

4. Inspect and Replace Drivetrain Components

Tools Required: Socket set, torque wrench.
Raise the vehicle and inspect the CV joints and axles for any cracks or wear.
If a CV joint is damaged, remove the axle shaft and replace the CV joint or the entire axle as necessary.
Ensure all bolts are torqued to specifications during reinstallation.
