Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Ensure the vehicle is on a flat surface and secure it with wheel chocks.
  • Disconnect the battery for safety if working on the suspension.
2. Inspect and Replace Suspension Components
  • Inspect Struts/Shocks:
    • Remove the wheel using a socket set.
    • Check for oil leakage around the strut/shock absorbers.
    • If damaged, proceed to replace them.
  • Replace Struts/Shocks:
    • Remove the top mounting bolts using a socket wrench.
    • Detach the lower bolts connecting the strut to the knuckle.
    • Install the new strut/shock by reversing the removal steps.
    • Torque the bolts to the manufacturer’s specifications (typically around 70-90 ft-lbs).
3. Tighten Loose Components
  • Check and Tighten Bolts:
    • Inspect all mounting bolts on the suspension components.
    • Use a torque wrench to tighten any loose bolts to factory specifications.
4. Replace Worn Bushings
  • Inspect Bushings:
    • Check the control arm and sway bar bushings for wear.
    • If worn, proceed to replace them.
  • Replace Bushings:
    • Remove the necessary suspension components to access the bushings.
    • Press out the old bushings and press in the new ones.
    • Reassemble components ensuring proper torque specs are followed.
