Question.
The jack screw says before use to lube it with gear oil, wouldn't it be better to use chassis grease on it ?

Fill it with grease I had one used it a couple times and the jack crossthreaded. I was using drill adapter also. Anyways it was under warranty and rep said that they dont put enough oil from factory and it causes problems. He told me to put a bunch of the thickest grease i can in it and worked great ever since

If you are able. Get the wheel kit so you can roll it around.

I have a lift similar to yours and has been great.
