Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely elevated using jack stands.
Disconnect the battery to prevent electrical issues during repair.

2. Inspect and Replace Worn Components

a. Control Arm Bushings

Remove the wheel to access suspension components.
Use a socket set to unbolt the control arm from the chassis.
Inspect the bushings for cracks or excessive wear.
If damaged, replace with OEM or quality aftermarket parts.
Torque the control arm bolts to manufacturer specifications.

b. Struts/Shocks

Locate the top and bottom mounting bolts of the strut.
Unbolt the strut from both the top and bottom.
Remove the strut from the vehicle.
Inspect for fluid leaks or physical damage.
Replace if necessary, ensuring to follow the manufacturer's torque specifications when installing.

c. Sway Bar Links

Inspect sway bar end links for damage.
Remove the bolts securing the sway bar link to the sway bar and lower control arm.
Replace with new components, ensuring proper alignment and torque.

3. Reassembly

Reinstall the wheels and lower the vehicle.
Reconnect the battery.
Check all bolts and components are secured properly.
