Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent electrical issues.

2. Inspect and Replace Worn Suspension Components

Remove the Wheel
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the lug nuts with a socket set and take off the wheel.
Check Shock Absorbers
- Inspect the shocks for leaks and physical damage.
- If damaged, unbolt the upper and lower mounting points using a socket set.
- Remove the old shock absorbers and replace them with new ones, ensuring to torque bolts to manufacturer specifications.
Examine Control Arms and Bushings
- Check for cracks or excessive play in control arms.
- If necessary, unbolt the control arm from the chassis and wheel hub.
- Replace any worn bushings and reassemble, torquing to specifications.
Tighten Loose Bolts
- Inspect all suspension-related bolts and hardware.
- Tighten any loose bolts to the correct torque settings.

3. Reassembly

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to specification.
Reconnect the battery after ensuring all components are secure.
