Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues.

2. Raise the Vehicle

Using a hydraulic lift or jack and jack stands, raise the vehicle securely.
Remove the wheels using a socket set.

3. Inspect and Replace Components

Struts/Shocks:
- Remove the strut assembly by loosening the top mount bolts and lower bolts.
- Inspect for leaks or damage, and replace if necessary.
- Install new struts, ensuring proper alignment and torque to manufacturer specifications (usually around 25-30 ft-lbs for strut bolts).
Bushings:
- Check control arm bushings for wear.
- If damaged, remove the control arm and press out the old bushings using a bushing removal tool.
- Install new bushings, ensuring they are seated properly.
Mounts:
- Inspect strut mounts for cracks or wear.
- If replacement is necessary, remove the strut from the vehicle and replace the mount.
- Reassemble and torque to manufacturer specifications.

4. Reassemble Suspension

Reattach the wheels and lower the vehicle.
Reconnect the battery.
Ensure all fasteners are torqued correctly and visibly inspect for any loose items.
