Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Use jack stands to support the vehicle safely after lifting.

2. Inspect and Replace Worn Bushings

Tools Required: Socket set, torque wrench, pry bar, lubricant.
Remove the wheel on the affected side of the suspension.
Use a pry bar to gently separate the control arm from the frame to relieve tension on the bushings.
Remove the retaining bolts and take out the worn bushings.
Clean the mounting surfaces and install new bushings, ensuring they are properly seated.
Reinstall the control arm and torque bolts to manufacturer specifications (typically 85-115 ft-lbs, check owner’s manual).
Reattach the wheel.

3. Replace or Lubricate Shocks/Struts

Tools Required: Socket set, wrench set, jack stands.
Remove the bolts securing the shock absorber to the lower control arm and upper mount.
Inspect the shock for leakage; if leaking, replace it with a new unit.
If the shocks are in good condition, apply appropriate lubricant to mounting points.
Reinstall the shock absorber and torque bolts to manufacturer specifications.

4. Inspect and Replace Sway Bar Links

Tools Required: Socket set, adjustable wrench.
Locate the sway bar links and check for any play or wear.
Remove the bolts securing the sway bar link to the sway bar and control arm.
Replace with new sway bar links if they show signs of wear.
Reinstall and torque to manufacturer specifications.
