Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Tire Balance Adjustment

Remove the wheels from the vehicle using a socket set.
Take the wheels to a tire shop to have them balanced using a dynamic balancing machine.
Reinstall the wheels, ensuring the lug nuts are torqued to the manufacturer's specifications (typically 80-100 ft-lbs).

3. Tire Pressure Check

Use a tire pressure gauge to check the pressure in each tire.
Inflate or deflate tires to match the manufacturer's recommended pressure (usually found on a sticker inside the driver’s door).
Recheck the pressure after adjustment.

4. Suspension Inspection and Repair

Inspect all suspension components including struts, shocks, and control arms for wear.
Replace any worn or damaged parts, ensuring to torque bolts to manufacturer specifications during reinstallation.
Consider an alignment if suspension components were replaced.

5. Wheel Bearing Inspection and Replacement

Lift the vehicle and secure it with jack stands.
Remove the wheels and brake calipers to access the wheel bearings.
Check for play by moving the wheel in and out. If movement is detected, replace the wheel bearing.
Reassemble the brake components and wheels, ensuring all fasteners are properly torqued.

6. Driveshaft and CV Joint Inspection

Inspect the CV joints for any torn boots or grease leakage.
Replace any damaged CV joints or driveshafts.
Ensure all components are securely fastened and inspected for proper alignment.
