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 Suspension Components

Tools Required: Socket set, torque wrench, jack stands, pry bar, and a multimeter.
Sub-steps:
1. Lift the front of the vehicle using a jack and secure it with jack stands.
2. Remove the front tires to access the suspension components.
3. Visually inspect control arms, ball joints, and bushings for any signs of wear or damage.
4. If components are worn, remove them using the socket set, noting the torque specifications for reassembly.
5. Install new components, ensuring proper alignment and torque settings are followed.

3. Check and Replace CV Joints

Tools Required: CV joint removal tool, grease, and protective gloves.
Sub-steps:
1. Remove the axle nut and disconnect the CV axle from the hub.
2. Inspect the CV joints for cracks or excessive play.
3. If the CV joint shows signs of wear, replace it with a new joint or complete axle assembly.
4. Reinstall the CV axle into the hub and tighten the axle nut to manufacturer's specifications.

4. Inspect Wheel Bearings

Tools Required: Torque wrench, bearing puller, and grease.
Sub-steps:
1. Check for play in the wheel bearings by shaking the wheel while it's off the ground.
2. If play is detected, remove the hub assembly and replace the wheel bearings.
3. Properly pack the new bearings with grease and reassemble the hub.
