Driveshaft wearing on swaybar?

I know this should go in suspension tuning but I never get a reply there. I have the KW VarientII's on chubs and it is making a high pitch squel one left hand turns. I can get under the car and see a line on the drive shaft and a tinny tiny silver mark on the swaybar (would expect much larger mark).
So I just got the Freedom Design front sway bar end links and put them on last night so I can change the angle of the swaybar. I made it shorter (about a 1/4 inch). I went out testing and here is what I have found, I can do turns as hard as I want as long as I am giving it throttle. But if I go into a turn and say 10mph and let off the gas before the turn I will hear the squel. On the same turn I can go 3 times the speed say 40mph and keep it lifted by throttle and nothing (be aware that the tires are rolling over themselves, the suspension is fully tilted).
So I go back into my pit (garage) and put it on the lifts (rhino ramps) and to my amazement there is no rubbing that I can see yet on the sway bar. Maybe it just takes longer to mark then I expect but is maybe something else I am missing. I know people are running their cars much lower with no problem.
