Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Shocks/Struts

Tools Required: Socket set, torque wrench, jack stands, floor jack, strut spring compressor (if replacing struts).
Instructions:
1. Use a floor jack to lift the vehicle and secure it with jack stands.
2. Remove the wheel to access the suspension components.
3. Unbolt the top and bottom mounts of the shock or strut.
4. If replacing struts, use a strut spring compressor to safely remove the coil spring from the strut assembly.
5. Install the new shock or strut in reverse order of removal, ensuring all bolts are torqued to manufacturer specifications.

3. Check and Adjust Wheel Alignment

Tools Required: Wheel alignment equipment.
Instructions:
1. After replacing shocks or struts, take the vehicle to a professional alignment shop.
2. Ensure that the alignment is adjusted to manufacturer specifications.
3. Test the vehicle post-alignment to confirm that the shaking has been resolved.

4. Inspect and Replace Worn Suspension Components

Tools Required: Socket set, torque wrench, floor jack, jack stands.
Instructions:
1. Conduct a thorough inspection of control arms, bushings, and ball joints.
2. If any component is damaged or worn, replace it with new parts.
3. Reassemble and torque all fasteners to specifications.
