Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely raise it using jack stands.
Disconnect the battery if electrical components are involved.

2. Inspect and Replace Rear Shock Absorbers

Tools Required: Socket set, torque wrench, penetrating oil.
Remove the nuts securing the top of the shock absorber using the socket set.
Locate the bolts at the bottom of the shock absorber and remove them.
Inspect the shock absorber for any signs of leakage or damage.
If damaged, install the new shock absorber:
- Position the new shock absorber in place.
- Secure the bottom bolt and torque to manufacturer specifications (typically around 30-40 Nm).
- Reattach the top nuts, ensuring they are tightened to the specified torque (usually around 20-25 Nm).

3. Replace Sway Bar Links

Tools Required: Wrench set, torque wrench.
Remove the nuts securing the sway bar links at both ends.
Inspect the sway bar links for any play or damage.
Install the new sway bar links:
- Position the new link and hand-tighten the nuts.
- Use the torque wrench to tighten to manufacturer specifications (usually around 35-40 Nm).

4. Replace Control Arm Bushings

Tools Required: Socket set, bushing removal tool, torque wrench.
Remove the bolts securing the control arm to the chassis and the wheel hub.
Use the bushing removal tool to extract the old bushings from the control arm.
Install new bushings:
- Press the new bushings into the control arm.
- Reinstall the control arm, torquing the bolts to specified values (typically 70-80 Nm).
