Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Raise the vehicle using a jack and secure it with jack stands.

2. Inspect and Replace Shocks/Struts

Sub-steps:
1. Remove the wheel to access the suspension components.
2. Disconnect the top and bottom bolts of the shock/strut assembly using a socket set.
3. Carefully remove the shock/strut assembly from the vehicle.
4. Install the new shock/strut by positioning it and securing it with the bolts (torque to manufacturer specifications).

3. Replace Bushings

Sub-steps:
1. Identify worn bushings by visual inspection or during the shake test.
2. Remove the suspension component (control arm or sway bar) that houses the bushings.
3. Use a bushing removal tool to extract old bushings.
4. Press in the new bushings and reinstall the component (torque as specified).

4. Wheel Alignment

Sub-steps:
1. After replacing parts, take the vehicle to a professional alignment shop.
2. Ensure that the alignment is performed to the manufacturer's specifications.
