Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat, level surface and engage the parking brake.
Disconnect the battery if required for component access.

2. Tire Inspection and Balancing

Tools Needed: Tire pressure gauge, jack, jack stands, lug wrench, wheel balancer.
Sub-steps:
1. Inspect each tire for signs of damage, bulging, or uneven wear.
2. Measure tire pressure and inflate to manufacturer specifications if needed.
3. Remove the wheels using the lug wrench.
4. Mount the wheels on a wheel balancer and adjust weights as necessary.
5. Reinstall the wheels, ensuring lug nuts are torqued to the specified value (typically 100-120 Nm).

3. Suspension Component Inspection

Tools Needed: Socket set, torque wrench, pry bar.
Sub-steps:
1. Visually inspect control arms, bushings, and struts for any signs of wear or damage.
2. Use a pry bar to check for excessive play in the bushings.
3. Replace any worn or damaged components following manufacturer's specifications.
4. Torque all bolts to the required specifications.

4. Driveshaft and Wheel Bearing Check

Tools Needed: Socket set, torque wrench, pry bar, dial indicator (for precise measurements).
Sub-steps:
1. Inspect the driveshaft for any visible damage or misalignment.
2. Check the U-joints for excessive play; replace if necessary.
3. Remove the wheel and inspect the wheel bearings for play by using a dial indicator.
4. Replace worn wheel bearings as per service manual instructions.
