Solution

1. Preparation

Gather all necessary tools and parts for the repair.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to ensure safety.

2. Inspect and Replace CV Joints

Tools Required: Socket set, torque wrench, CV joint boot clamps, grease.
Sub-steps:
1. Lift the front of the vehicle using a jack and secure it with jack stands.
2. Remove the front wheel to access the CV joint.
3. Inspect the CV joint boot for tears; replace if damaged.
4. If the CV joint is worn, remove the axle nut using a socket wrench.
5. Disconnect the axle from the hub assembly and remove the CV joint from the axle.
6. Install the new CV joint, applying the appropriate grease, and reassemble in reverse order.
7. Torque the axle nut to manufacturer specifications (typically around 200 Nm).

3. Inspect and Replace Wheel Bearings

Tools Required: Bearing puller, socket set, torque wrench.
Sub-steps:
1. After removing the wheel, take out the brake caliper and rotor.
2. Use a bearing puller to remove the old wheel bearing from the hub.
3. Clean the bearing seat and install the new wheel bearing.
4. Reassemble the brake rotor and caliper, ensuring all bolts are torqued to specification.

4. Inspect and Replace Tie Rod Ends or Ball Joints

Tools Required: Socket set, ball joint separator, torque wrench.
Sub-steps:
1. Remove the front wheel to access the tie rod ends and ball joints.
2. Use a ball joint separator tool to detach the tie rod end from the steering knuckle.
3. Inspect the tie rod and ball joint for any play or damage; replace if necessary.
4. Install the new tie rod end or ball joint and torque to specifications.
