If you use grease, you can stay level.So the “hydraulic” pressure is the way to go then.
how many degrees do you pitch the car to?
Just make sure you clean up any lubricant from the tapers prior to re-installation.
Also make sure there is no remaining grease in the hole for the securing bolt.
If there is remaining grease in the hole you can get a hydraulic lock up and the bolt will not torque up properly.
