Solution

1. Preparation

Ensure the vehicle is parked on a flat surface.
Gather necessary tools and parts.
Disconnect the battery for safety.

2. Inspect and Replace Suspension Components

Raise the Vehicle
- Use a hydraulic lift or jack stands to elevate the vehicle securely.
- Safety warning: Ensure the vehicle is stable before working underneath.
Remove Wheel
- Use a socket set to remove the lug nuts and take off the wheel.
- Tools required: Socket set, lug wrench.
Inspect Suspension Assembly
- Check control arms, bushings, and struts for wear or damage.
- Look for any cracks or breaks in the components.
Replace Damaged Components
- If any components are damaged, replace them with OEM parts.
- Follow torque specs for reassembly (typically around 70-90 ft-lbs for control arm bolts).
- Tools required: Torque wrench, new control arms/bushings.

3. Inspect and Replace CV Joints

Check CV Joints
- Inspect the CV joint boots for any tears or grease leaks.
- If damaged, the CV joint should be replaced.
Remove CV Axle
- Remove the axle nut using a socket set.
- Disconnect the CV axle from the wheel hub and differential.
- Tools required: Socket set, pry bar.
Install New CV Joint/Axle
- Replace the old CV joint/axle with a new one.
- Reassemble and torque the axle nut to manufacturer specifications (typically around 150-200 ft-lbs).
- Tools required: Torque wrench.
