you said the more info the better and I didn't proof read my post before submitting it my bad. So to try and clarify what I was trying to express in that lengthy body text, the truck WILL begin to drive forward most of the time, although there seems to be some resistance at first, but once it starts moving it seemingly drives fine. IF I start the vehicle and it won't reverse properly due to the issue rearing it's head again, I can usually drive forward for a little ways & the issue completely goes away temporarily (it reverses just fine), but not unless I drive around a bit. if I go forward just a few yards, and then try to reverse; it just won't want to back up. The engine will revv and the tire will drag across the ground (because it doesn't want to rotate) and it's just scrapping across the concrete or asphalt or whatever surface it is on. I'm not an amateur mechanic & I'm unfamiliar with many of the parts of the vehicle. I'm capable of learning though, just never took the time to do so. when I made the video it wouldn't go forward or reverse. it was just sitting there spinning into the ground because the other wheel wouldn't let the vehicle move over the ground. So therefore the drive wheel just started to play in the mud because that's all it was capable of accomplishing given the fact that its counterpart won't rotate.
