Solution

1. Preparation

Gather all necessary tools and parts.
Elevate the vehicle using a hydraulic lift or jack stands for safety.
Remove the wheels to access the suspension components.

2. Inspect and Replace Suspension Components

Check Shock Absorbers:
- Inspect for any leaks or physical damage.
- If damaged, remove the old shock absorbers by unscrewing the upper and lower mounting bolts.
- Install new shock absorbers, ensuring they are tightened to the manufacturer’s specifications (typically around 25-30 Nm for upper mounts).
Inspect Sway Bar Links:
- Remove the sway bar link bolts using a socket set.
- Check bushings for wear; replace if necessary.
- Install new sway bar links and torque bolts to the manufacturer's specifications.
Control Arms and Bushings:
- Remove the control arm bolts and inspect bushings for cracks or excessive wear.
- Replace any worn bushings with new ones, using a bushing press if necessary.
- Reinstall the control arms and torque to specifications.

3. Reassemble and Lower Vehicle

Reinstall the wheels and tighten lug nuts in a crisscross pattern.
Lower the vehicle back to the ground and torque the lug nuts to the manufacturer’s specifications (usually around 120 Nm).
