Solution

1. Preparation

• Park the vehicle on a level surface and engage the parking brake.
• Gather tools and parts for the repair.
• Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, stethoscope, and possibly a multimeter.

2. Inspect and Replace Suspension Components

• Step 1: Lift the vehicle and secure it on jack stands.
• Step 2: Remove the front or rear wheels (as applicable) to access suspension components.
• Step 3: Inspect control arms, bushings, and shock absorbers for wear or damage.
• Step 4: If any components are found to be worn, remove them using the socket set.
  • Note: Mark the alignment settings if necessary to maintain proper wheel alignment.
• Step 5: Install new suspension components, ensuring they are properly torqued to manufacturer specifications.
  • Torque values: Refer to the vehicle service manual for specific torque values for each component.

3. Inspect and Replace Drivetrain Components

• Step 1: Check CV joints and wheel bearings for any signs of damage or excessive play.
• Step 2: If CV joints are damaged, remove the axle from the hub and replace with a new unit.
• Step 3: For wheel bearings, remove the hub assembly and replace the bearing, ensuring proper installation and torque.
