Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Inspect and Replace CV Joints

Sub-steps:
1. Raise the front of the vehicle using a jack and secure it on jack stands.
2. Remove the front wheel to access the CV joint.
3. Inspect the CV boot for any tears or grease leaks. If damaged, replace the CV joint.
4. Remove the axle nut and split the CV joint from the hub.
5. Install the new CV joint and torque the axle nut to the manufacturer’s specifications (usually around 150 ft-lbs).
6. Reinstall the wheel and lower the vehicle back to the ground.

3. Inspect and Replace Suspension Components

Sub-steps:
1. Check the struts, shocks, and control arms for wear or damage.
2. If any component is damaged, remove the affected part by loosening bolts (usually involves a socket set).
3. Replace with OEM or quality aftermarket parts, ensuring correct torque specifications for all bolts.
4. Reassemble any removed components and secure all connections.

4. Test Steering Linkage

Sub-steps:
1. Inspect tie rods and steering rack for any looseness.
2. If damaged, remove the tie rod ends by loosening the pinch bolt and separating them from the steering knuckle.
3. Replace with new tie rod ends, ensuring to adjust the alignment afterward.
4. Reinstall and ensure all connections are secure.
