Well, yes, if you trust the ramps.

I've never owned ramps, because I was too cheap to buy the really good ones. I have reason to believe that the entry-level ramps rather unsafe in their capacities. I have read of and seen pics of collapsed ramps, but have never seen them collapse(d)/fail in person.

Do you have a hand-pump to draw the old fluid out of the casing? Or, are you planning on draining it?
