Solution

1. Preparation

Gather tools and parts required for repair.
Place the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on components.

2. Tire Inspection and Balancing

Tools Required: Tire balancing machine, jack, jack stands, lug wrench.
Remove the wheel by loosening the lug nuts and using a jack to lift the vehicle.
Inspect the tire for bulges, cuts, or uneven wear.
Balance the tire using a tire balancing machine and remount it on the vehicle.
Torque the lug nuts to manufacturer specifications (typically around 100-110 Nm).

3. Suspension Component Inspection

Tools Required: Socket set, torque wrench, pry bar.
Inspect control arms, bushings, and ball joints visually and by hand for play or cracking.
Replace any damaged components with new parts.
Torque all suspension bolts to the manufacturer's specifications.

4. Driveshaft and CV Joint Inspection

Tools Required: Socket set, pry bar.
Inspect the driveshaft for any signs of bending or damage.
Check CV joints for any grease leaks or wear.
