Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues during repairs.

2. Inspect and Replace Wheel Bearings

Tools Required: Jack, jack stands, socket set, torque wrench, wheel bearing puller
Lift the vehicle and remove the wheel.
Inspect the wheel bearing for play or roughness; replace if necessary.
- If replacement is needed:
  1. Remove the brake caliper and rotor.
  2. Use a wheel bearing puller to extract the old bearing.
  3. Clean the hub area and install the new bearing, ensuring it is seated properly.
  4. Reassemble the brake components and wheel, torquing bolts to manufacturer specifications.

3. Inspect and Replace CV Joints

Tools Required: Socket set, pry bar, CV joint removal tool
Examine the CV joints for any tears in the rubber boot or evidence of grease leakage.
- If replacement is necessary:
  1. Remove the wheel and axle nut.
  2. Use a pry bar to detach the CV joint from the hub.
  3. Slide the inner CV joint off the axle, ensuring to support the transmission.
  4. Install the new CV joint by reversing the removal steps and ensure proper seating.

4. Suspension Inspection and Repair

Tools Required: Socket set, torque wrench, suspension tool kit
Inspect all suspension components for wear, including bushings, struts, and links.
- Replace any worn components with new parts:
  1. Remove the affected suspension parts by loosening and removing bolts.
