Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat, stable surface and securely lift the vehicle using jack stands.
Disconnect the battery to avoid any electrical issues.

2. Inspect and Tighten Suspension Components

Tools Required: Socket set, torque wrench
Inspect strut and shock mounts for any looseness.
Tighten all suspension bolts and nuts to manufacturer specifications using a torque wrench.

3. Replace Worn Components

Tools Required: Wrench set, strut spring compressor (if replacing struts), jack stands
If any components such as struts, shocks, or sway bar links are found to be damaged:
1. Remove the wheel to access suspension components.
2. Use a strut spring compressor to safely compress the spring if replacing struts.
3. Remove and replace the damaged component with a new part.
4. Reassemble components in reverse order and ensure all bolts are torqued to specifications.

4. Recheck Alignment

Tools Required: Alignment tools (if available)
After replacing parts, check the wheel alignment as suspension repairs can affect alignment settings.
Adjust if necessary to manufacturer specifications.
