First put the car in D and turn engine off and set brake.

The bottom section of the **** screws off. You may have to use a gripper or something similar to turn it. DO NOT USE ANY TYPE OF TOOL, it is very easy to damage. Once the bottom section is loose from the main ****, simply pull straight up, sometimes very very hard.

I have tried two different aftermarket *****, both needed to be drilled deeper to fit properly.
