Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Front Suspension Components

Tools Required: Socket set, torque wrench, pry bar, ball joint separator, jack stands.
Sub-steps:
1. Lift the front of the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels using a socket set.
3. Inspect the control arms, ball joints, and bushings for wear; replace any damaged components.
  - To replace a ball joint, use a ball joint separator to disconnect it from the steering knuckle.
  - Remove the mounting bolts and install the new ball joint, tightening to manufacturer specifications.
4. Reassemble all components, ensuring proper alignment of the control arms and bushings.
5. Torque all bolts to the specifications found in the service manual.

3. Inspect and Replace CV Joints

Tools Required: Socket set, CV joint puller, grease.
Sub-steps:
1. Remove the axle nut using a socket set.
2. Disconnect the CV joint from the wheel hub.
3. Inspect the CV joint for damage; replace if necessary by removing the joint from the axle shaft.
4. Install the new CV joint, ensuring to apply appropriate grease to the joint.
5. Reattach the axle to the wheel hub and torque the axle nut to specification.

4. Check and Replace Wheel Bearings (if necessary)

Tools Required: Bearing puller, socket set.
Sub-steps:
1. Remove the brake caliper and rotor to access the wheel bearing.
2. Use a bearing puller to remove the old bearing from the hub.
3. Install the new bearing, ensuring it is pressed in evenly.
4. Reassemble the brake rotor and caliper, securing them to specifications.
