Pressing out and in U-Joints and some bearings seals a little on the short side differently would mount it on a sturdy sturdy work bench of some kind. The only thing i had a problem with is getting the bottle jack to work properly i could only get it to extended 1-2\" at first but was able to get it working good eventually.
Easy to assemble, lots of power, very good quality. Affordable pricing. I would though recommend to buy the longer version if you have the space. Managed to separate an alloy assembly that was actually in one piece… Oops 🤣 As said, lots of power!
