Solution

1. Preparation

Gather tools and workspace.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electronic components.

2. Tire Inspection and Replacement

Remove the wheel covers or hubcaps if applicable.
Loosen the lug nuts using a socket set and remove the wheels.
Inspect tires for damage, bulges, or uneven wear. Replace if necessary.
Ensure tires are inflated to manufacturer specifications (check the owner’s manual for PSI settings).
Reinstall the wheels and torque the lug nuts to the manufacturer’s specifications.

3. Suspension and Drivetrain Inspection

Raise the vehicle using a jack and secure it with jack stands.
Visually inspect all suspension components including control arms, bushings, and struts for signs of wear or damage.
Check the driveshaft and CV joints for any signs of wear, including torn boots or excessive play.
If any components are damaged, replace them with OEM or quality aftermarket parts.

4. Wheel Alignment

After inspecting and replacing any worn components, take the vehicle to a professional alignment shop.
Request a four-wheel alignment to ensure all wheels are properly aligned.
