Landing gear issues

I have had issues with the landing gear since I've owned my AF. I drilled holes and lubed the jack screw with white lithium spray lube and it helps. But I find that it still struggles to lift the front of the trailer as high as I need it on my driveway (which slopes down). My next mod to my trailer is going to be a dual motor setup. Unfortunately, my landing gear is incompatible with all of the dual motor kits offered (I don't want to mess with having new brackets welded onto my frame). So, I'm simply going to replace my driven leg with another matching drive leg and replace both motors/gearboxes to ensure they are speed matched.
