Replacing a clutch kit is a complex and time-consuming process that requires some knowledge and experience in car mechanics. However, if you want to do it yourself, here are the general steps:

1. Disconnect the battery: This is to avoid any electrical shock while working on the clutch kit.

2. Remove the drive shaft and transmission: You will need to access the clutch from underneath the vehicle. Ensure the car is lifted and supported by jack stands.

3. Remove the old clutch: Carefully take out the old clutch disc, pressure plate, and release bearing. You may need a clutch alignment tool to remove the old clutch.

4. Inspect flywheel: Check the flywheel for oil, cracks, and other damage. Smooth out any uneven surfaces by resurfacing it or replacing it outright.

5. Install the new clutch kit: Install the new clutch components (pressure plate, clutch disc, and release bearing) by using the aligning tool. Tighten them according to specifications provided with the kit.

6. Reinstall the transmission and drive shaft: Carefully reattach the transmission and the drive shaft according to factory specifications.

7. Test drive: After completing installation, test drive the vehicle to ensure that the clutch is functioning correctly.

It is important to note that the complexity of this process may vary depending on the make and model of your car. Additionally, you may need specialized tools such as a transmission jack and torque wrench to complete the process.
