Solution

1. Preparation

• Park the vehicle on a flat surface and engage the parking brake.
• Gather necessary tools and parts for the repair.

2. Raise the Vehicle

• Use a jack to lift the vehicle and secure it with jack stands.
• Ensure the vehicle is stable before proceeding.

3. Inspect and Replace Suspension Components

• Inspect Struts and Shocks:

  • Remove the wheel to gain access to the strut or shock assembly.
  • Check for leaks or physical damage; replace if necessary.

• Replace Sway Bar Links:

  • Locate the sway bar links and check for play or damage.
  • Remove the nuts securing the sway bar links using a socket set.
  • Install new sway bar links and torque to manufacturer specifications (typically 30-40 Nm).

• Check Control Arms:

  • Inspect the control arms for bushings that may be worn out.
  • Replace control arms if bushings are damaged or if there are cracks in the metal.

4. Reassemble

• Reattach the wheel and lower the vehicle back to the ground.
• Perform a torque check on the wheel lug nuts to manufacturer specifications (typically 100-120 Nm).
