Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and is secured with wheel chocks.
Raise the vehicle using a jack and support it with jack stands.

2. Inspect and Replace Suspension Components

Visual Inspection:
- Inspect struts and shocks for leaks or damage.
- Check rubber bushings for cracks or deterioration.
Replace Damaged Components:
- Remove the old struts/shocks (use a socket set) and replace them with new parts.
- Ensure all nuts and bolts are torqued to manufacturer specifications (consult repair manual for torque values).
Install New Bushings (if necessary):
- Remove any worn bushings using a bushing removal tool.
- Press in new bushings and lubricate them as per manufacturer recommendations.

3. Check and Adjust Wheel Alignment

Align the Vehicle:
- After replacing any damaged suspension components, take the vehicle to a professional alignment shop.
- Ensure all specifications are met according to the manufacturer's alignment settings.

4. Inspect Steering Components

Examine Steering Linkage:
- Check tie rods and ball joints for play or wear by shaking the components.
- Replace any worn tie rods or ball joints with new ones (use a tie rod separator if necessary).

5. Test Drive the Vehicle

After repairs, test drive the vehicle to ensure the vibration issue has been resolved.
