Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Tire Inspection and Replacement

Inspect Tires:
- Remove the hubcaps or wheel covers if equipped.
- Check for bulges, punctures, or uneven wear.
Replace Tires (if necessary):
- Loosen the lug nuts with a lug wrench.
- Jack up the vehicle and secure it with jack stands.
- Remove the lug nuts and take off the affected tire.
- Mount the new tire and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to manufacturer specifications (typically around 80-100 ft-lbs).

3. Suspension Component Replacement

Inspect and Replace Shocks/Struts:
- Remove the wheel to access the suspension components.
- Unbolt the upper and lower mounting points of the strut.
- Replace the strut with a new one, ensuring to follow torque specifications (usually 15-20 ft-lbs for upper bolts and 50-60 ft-lbs for lower).

4. Wheel Bearing Inspection and Replacement

Inspect Wheel Bearings:
- Rotate the wheel and listen for grinding or roughness.
Replace Wheel Bearings (if necessary):
- Remove the wheel and brake assembly.
- Unbolt the wheel hub and replace the bearing with a new one.
- Reassemble the brake components and wheel, tightening to specification (typically around 80-100 ft-lbs).

5. Driveshaft/CV Joint Inspection and Replacement

Inspect Driveshaft/CV Joints:
- Check for any torn boots or excessive play.
Replace CV Joints (if necessary):
- Remove the wheel and axle nut.
- Disconnect the CV joint from the transmission or wheel hub.
- Install the new CV joint and torque the axle nut to manufacturer specifications (around 100-120 ft-lbs).
