Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, pry bar, and a multimeter.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal if working on electrical components.

2. Inspect and Replace CV Joints

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels using a lug wrench.
3. Inspect the CV joint boots for tears; if damaged, remove the axle assembly.
4. Using a socket set, unbolt the CV joint from the wheel hub.
5. Pull the axle out from the transmission side, inspect the inner CV joint as well.
6. Replace any damaged CV joints with new units; ensure proper alignment during installation.
7. Reassemble by reversing the disassembly steps, ensuring all bolts are torqued to manufacturer specifications.

3. Inspect and Replace Suspension Components

Sub-steps:
1. While the vehicle is still elevated, visually inspect all suspension components for wear or damage.
2. Use a pry bar to check for excessive play in the control arms and bushings.
3. Replace any worn components such as control arms or bushings.
4. Reassemble all parts and torque bolts to the appropriate specifications.
