Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a flat surface, and secure it with wheel chocks.
• Disconnect the battery to ensure safety while working on the vehicle.

2. Inspect and Replace CV Joints

• Tools Required: Socket set, torque wrench, CV joint puller, grease, jack stands.
• Sub-steps:
  1. Lift the front of the vehicle and secure with jack stands.
  2. Remove the front wheels using the socket set.
  3. Inspect the CV boots for cracks or tears; replace if damaged.
  4. If the CV joints are worn, use the CV joint puller to remove them from the axle shaft.
  5. Install new CV joints by sliding them onto the axle shaft and securing with the retaining clips.
  6. Reassemble the assembly and torque the axle nut to the manufacturer’s specifications (typically around 200 Nm).

3. Check and Replace Wheel Bearings

• Tools Required: Bearing puller, socket set, torque wrench.
• Sub-steps:
  1. Remove the brake caliper and rotor.
  2. Use the bearing puller to extract the wheel bearing from the hub.
  3. Clean the hub area and install the new bearing with the puller.
  4. Reinstall the brake rotor and caliper, ensuring to torque the caliper bolts to specifications (typically around 30 Nm).

4. Inspect and Replace Suspension Components

• Tools Required: Socket set, pry bar, torque wrench.
• Sub-steps:
  1. Inspect control arms, bushings, and struts for signs of wear.
  2. If any components are damaged, remove them using the socket set and pry bar.
  3. Install new components and ensure they are torqued to the specified values (check manufacturer specifications).
