I think the dealer just replaced the shear bolt, and now it is repaired. Not the current question.
As I read the question, OP is wondering if he can remove the cross-over drive shaft, and go on living with independent level legs.
And the answer is clearly yes, you could do that. But are you sure you want to? I have often camped where I needed 10 inches of leg travel to level the rig. So I would have to run the legs out to support the trailer while I unhitched from the truck, and then need 10 inches of travel to get level. Would I want to have to go back and forth between left/right legs with a cordless drill, a little at a time on each? Does not sound like a good idea to me.
What does sound like a better idea is to remove the equalizing drive shaft, and install a second motor on the off side. Then wire in a separate switch. Then you could depress both switches for fast travel, get them down near the ground together, then fine tune your level using the switches. You would also benefit from double the driving power. But cordless drill and running side to side? Nope.
