Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working with electrical components.

2. Inspect and Replace CV Joints

Lift the Car:
- Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove Wheel:
- Use a socket set to remove the lug nuts and take off the front wheel.
Check CV Joints:
- Inspect the outer CV joint for cracks or tears in the boot. If damaged, proceed with replacement.
Remove CV Axle:
- Remove the axle nut using a socket wrench. Disconnect the CV joint from the hub assembly and pull it out of the transmission.
Install New CV Joint:
- Insert the new CV joint into the transmission and secure it with the axle nut. Torque the nut to manufacturer specifications (typically 200 Nm).
Reassemble:
- Reattach the wheel, tighten the lug nuts in a crisscross pattern, and lower the vehicle.

3. Inspect and Replace Suspension Components

Visual Inspection:
- Check the control arms, bushings, and strut mounts for any wear or damage.
Replace Damaged Parts:
- If any components are worn, remove them using a socket set and replace with new OEM parts.
Reinstall Components:
- Torque all bolts to manufacturer specifications.
