Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface and securely raise the front using jack stands.
• Disconnect the battery to prevent any electrical issues during inspection.

2. Inspect and Replace Suspension Components

• Inspection:
  • Check the front struts for leaks or damage.
  • Examine sway bar links and bushings for wear or looseness.
• Replacement:
  • If any components are damaged, remove the old parts:
    1. Use a socket set to remove the bolts securing the struts and sway bar links.
    2. Replace with new parts, ensuring all bolts are torqued to manufacturer specifications (typically around 50-80 ft-lbs for strut bolts).

3. Inspect and Replace Drivetrain Components

• Inspection:
  • Examine CV joints for torn boots or play.
• Replacement:
  • If CV joints are damaged:
    1. Remove the axle nut using a socket.
    2. Disconnect the lower control arm to access the CV joint.
    3. Replace the CV joint or entire axle assembly if necessary. Torque the axle nut to manufacturer specifications (usually 150 ft-lbs).

4. Inspect Engine Mounts

• Inspection:
  • Check the engine mounts for cracks or excessive movement.
• Replacement:
  • If necessary, replace the engine mounts:
    1. Support the engine with a jack.
    2. Remove the bolts securing the mount to the engine and frame using a socket set.
    3. Install the new mount and torque to specification.
