Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Use jack stands to lift the vehicle safely and remove the wheels.

2. Inspect and Replace Worn Components

Suspension Struts/Shocks:
- Remove the retaining bolts securing the strut/shock to the hub.
- Disconnect the upper strut mount from the chassis.
- Remove the strut/shock assembly.
- Replace with new struts/shocks and reassemble in reverse order. Torque specifications: 60 Nm for lower bolts and 25 Nm for upper bolts.
Control Arms:
- Remove bolts securing the control arm to the chassis and wheel hub.
- Inspect bushings for wear and replace if necessary.
- Install new control arms and torque to manufacturer specifications (typically around 90 Nm).
Sway Bar Links:
- Disconnect the sway bar link from the sway bar and control arm.
- Install new sway bar links and torque to proper specifications (about 40 Nm).

3. Reassemble and Reinstall

Reinstall the wheels and lower the vehicle.
Ensure all components are secured and tightened according to specifications.
