Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery if working on electronic suspension components.

2. Inspect and Replace Worn Components

Struts/Shocks:
- Remove the wheel to access the strut assembly.
- Unbolt the strut from the upper mount and lower control arm.
- Replace with new struts or shocks, ensuring correct alignment.
- Torque the strut bolts to the manufacturer's specifications (typically around 40-60 ft-lbs).
Bushings:
- Identify and remove any damaged bushings in the control arms or sway bar links.
- Press in new bushings with a bushing tool or a suitable press.
Control Arms:
- If control arms are bent or damaged, unbolt them from the chassis and knuckle.
- Replace with OEM or aftermarket control arms, ensuring alignment with mounting bolts.
- Torque control arm bolts to manufacturer specifications.

3. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Reconnect the battery if it was disconnected.
Ensure all fasteners are torqued properly.
