Solution

1. Tire Inspection and Adjustment

Sub-steps:
1. Check tire pressure using a tire gauge; adjust to manufacturer specifications if necessary (usually found on the driver’s door jamb).
2. Look for any bulges, cuts, or uneven wear on the tire tread.
3. Rotate tires if needed to ensure even wear.

2. Wheel Lug Nut Torque

Sub-steps:
1. Use a torque wrench to check the lug nut torque; refer to the manufacturer’s specifications (typically around 80-100 ft-lbs for most vehicles).
2. Tighten any loose lug nuts to the specified torque using a star pattern to ensure even distribution.

3. Suspension Component Replacement

Sub-steps:
1. Inspect suspension components closely (control arms, bushings, shocks) for any signs of wear or damage.
2. Replace any worn or damaged components with OEM or high-quality aftermarket parts.
3. Reinstall components and ensure all bolts are torqued to specifications.

4. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Perform a four-wheel alignment and adjust camber, caster, and toe settings to meet manufacturer specifications.
3. Test drive after alignment to ensure the shaking has resolved.

5. Driveshaft and Axle Inspection

Sub-steps:
1. Inspect the driveshaft for any signs of imbalance, such as dents or bends.
2. Check the axles for any signs of damage or play in the joints.
3. Replace any damaged driveshaft or axle components as necessary.
