Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery if working on electrical components.

2. Inspect and Replace CV Joints

Tools Required: Socket set, torque wrench, pry bar, CV joint puller.
Remove the front wheels using a socket set.
Use a pry bar to carefully remove the CV joint from the wheel hub.
Inspect the CV joint and boot for any signs of wear or damage.
If damaged, replace the CV joint by reversing the removal process and ensuring proper torque specifications during reassembly.

3. Check and Replace Wheel Bearings

Tools Required: Bearing puller, socket set, torque wrench.
After removing the wheel, inspect the wheel bearings for any signs of wear or play by manually spinning the hub.
If the bearings are damaged, use a bearing puller to remove the old bearings from the hub and replace them with new ones.
Reassemble the hub and wheel, ensuring all components are properly torqued.

4. Inspect and Tighten Suspension Components

Tools Required: Socket set, torque wrench.
Check all suspension components, including control arms, struts, and bushings for signs of wear or looseness.
Tighten any loose bolts to the manufacturer’s specified torque values.
