Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if working on electronic components.

2. Inspect and Replace Suspension Components

Tools Required: Socket set, torque wrench, jack, jack stands, pry bar.
Check the shock absorbers for leaks or damage.
- If defective, remove the shock absorber by:
  1. Lifting the vehicle and securing it with jack stands.
  2. Removing the lower mounting bolts using a socket.
  3. Detaching the upper mounting point (may require accessing the vehicle's interior).
  4. Installing the new shock absorber by reversing the removal steps.
  5. Torque the bolts to manufacturer's specifications (typically around 50-70 ft-lbs).

3. Inspect and Replace Bushings

Tools Required: Pry bar, socket set, torque wrench.
Examine control arm and sway bar bushings for wear.
- Replace if necessary by:
  1. Removing the control arm or sway bar from the vehicle.
  2. Using a pry bar to remove old bushings.
  3. Pressing in new bushings using a suitable tool or vice.
  4. Reinstalling the control arm or sway bar and torque all bolts to spec.

4. Lubricate Components

Tools Required: Grease gun, appropriate grease.
Apply lubricant to all moving parts of the suspension:
- Focus on joints, bushings, and sway bar links to reduce friction and noise.
