Solution

1. Preparation

Gather all tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues.

2. Inspect and Replace Components

Inspect Shock Absorbers and Struts
- Remove the wheels using a socket set.
- Check for leaks or physical damage on shocks/struts.
- If damaged, remove the assembly by unbolting from the top mount and lower control arm.
- Replace with new shock absorbers or struts, ensuring they are correctly seated and tightened to manufacturer's torque specifications.
Check Control Arms and Bushings
- Inspect control arms for cracks or deformation.
- If bushings are worn, support the control arm, remove the bolts, and replace bushings using a press.
- Reassemble the control arm and tighten bolts to the specified torque.

3. Alignment

After replacing any components, perform a wheel alignment using an alignment machine.
Ensure all specifications are within manufacturer tolerances.

4. Final Assembly

Reinstall the wheels and torque the lug nuts to the specified values.
Reconnect the battery and check for any warning lights.
