Front landing leg motor replacement help/question

I think I might need a new front landing leg motor. My problem started the last few times out where when I use the extend/retract switch it either starts extremely slow and gains a little speed as it goes and will vary between slowing and gaining speed. Its not like its a constant speed once it runs. Or it will do nothing at all, so I grab the bar that goes between the legs and start to turn it myself and press the button for the extend/retract and it might start, although when it starts its slow as molasses and once again will vary between slowing and gaining speed.

We went out this weekend and when I came back to the storage yard it did nothing so I hand cranked it down.
I know the battery is good since I can put the slides out with no problems and even tried the landing legs with jumper cables from my truck to the fiver battery with no difference. The lights don’t dim when pressing the extend/retract button either.

My question is, since I have never taken off the motor or gearbox off before and the fiver is sitting in the storage lot, can I pull the motor and gear box off without fear of the landing legs giving way while I take them off?
I think that answer is yes but wanted to double check with you guys. I think that one the legs are down they are down and the motor and gearbox is not ‘holding them’ so its safe to remove them.

I wanted to take them off, check the motor itself with some jumper cables to see if it works and take apart the gearbox and grease it up since I already have it off. When I was de-winterizing a few weeks ago I did pop odd the tops of the landing legs and the gears were lubed but I also put some more in. I don’t think that the gearbox or lack up lube is the problem because hand cranking it was not a big deal and everything moved freely, just time consuming to crank them down.

Let me know what you guys think
