Don't do it. I really don't know how much preload it has but relative to finger, hands, arms and eyes, a heck of alot.
If it is anything like a 150, my son picked up the front end (no motor or transmission) with one side when trying to get at something in the suspension. He did not go further and is waiting for info before another attempt.
