Axle hop is what you mean. You don't have bad axle wrap. I have more wrap now with my overloads out but never had hop. I think hop is just an inescapable pickup thing. Axle wrap is when your axle twists when you accelerate hard.
Axle hop is created by axle wrap. The torque of the axle is transferred to the leaf springs, where they rapidly load up and release the energy (hop). So if he has bad axle hop, yes he has axle wrap. Your truck probably just has bent leaves, so it won't hop when it wraps anymore. My old Tacoma used to be able to bend brand new leaves in a month with axle wrap. When it stopped bouncing so hard when I was drag racing somebody, then I knew they were done for. Axle hop is not an inescapable pickup thing. It's just a crappy leaf spring setup thing.
Birfection, with the traction bar the hop should be limited, so you can set up a nice soft spring rate without the consequences. The drawback of a traction bar is that its yet another thing hanging down to hang your truck up on. However, I have seen some that were done very well and tucked up nice.
An anti-wrap leaf is a leaf cut in half, that is placed at the top of the pack facing the front. This resists the wave motion of the springs when they wrap. This will likely stiffen the suspension some, but not as much as a full leaf. The drawback of this is that you can still get axle hop with enough torque. It's just a limiter.
The fool-proof method to get a nice soft spring rate with no wrap whatsoever is to chop off the leaf springs, and do a link suspension.
Can a 22R axle wrap? Oh yeah.. Wait until you're hung up on something, then you will really see it happen. My 20R can wrap up the springs just taking off from a light quickly. Granted it doesn't do it nearly as bad as my old Tacoma did.
But really, you should just try it. It doesn't take too much time, and it (shouldn't) cost you anything. I'm running stock Tacoma leaf springs with the overload pulled, and the axle wrap isn't enough to bother me. I have a flat bed, but it's probably about the same weight as the stock bed or more. Eventually I will 4-link it, but for now it's fine.
