Solution

1. Preparation

Tools Required: Vehicle lift or jack, jack stands, socket set, torque wrench.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery (negative terminal) to prevent electrical issues during inspection.

2. Inspect Suspension Components

Sub-steps:
- Lift the vehicle using a vehicle lift or jack, securing it with jack stands.
- Visually inspect the shock absorbers for any leaks or physical damage.
- Check the upper and lower control arms for any signs of wear or play.
- Examine the bushings for cracks or deterioration.

3. Tighten or Replace Components

Sub-steps:
- Use a socket set to check the torque on all suspension bolts and fasteners.
- If any bolts are loose, tighten them to the manufacturer's specifications (refer to service manual for torque values).
- If components show signs of wear, replace them with OEM or high-quality aftermarket parts.

4. Test Suspension Operation

Sub-steps:
- After reassembling, lower the vehicle safely back to the ground.
- Push down on each corner of the vehicle to observe the rebound of the suspension.
- Ensure each corner returns to its original position without excessive bouncing or noise.
