Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if working on electronic components near the suspension.

2. Inspect and Replace Shocks/Struts

Tools Required: Socket set, torque wrench, jack, jack stands, spring compressor (if applicable).
Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheels to gain access to the suspension components.
3. Disconnect any electrical connectors from the shocks or struts if equipped with electronic damping.
4. Unbolt the top mount of the strut and the lower mount at the knuckle.
5. Carefully remove the strut assembly. If necessary, use a spring compressor to release the spring tension.
6. Replace the old strut or shock with a new unit, ensuring it is properly seated.
7. Reattach the top and bottom mounts and torque to manufacturer specifications (typically, consult the service manual for exact torque values).

3. Replacing Worn Sway Bar Links

Tools Required: Socket set, torque wrench.
Sub-steps:
1. Locate the sway bar links connected to the sway bar and lower control arm.
2. Remove the nuts securing the sway bar link using a socket.
