I think he means putting some toe in on the rear tires. But doing this wont help a this just helps with overall traction. If you have toe in, in the rear it will help you in acceleration. Try the toe out in the front end, this should help, if it doesnt then something else is off. How fast are you going when your trying to turn also are you on the gas when trying to turn.

If you at speed the truck will take longer to turn as it's going pretty fast. If your on the gas the weight is transfered to the rear, which puts less weight on the front end, which will make the truck turn like a truck. All trucks when your going at a high rate of speed, or if your on the gas will turn like a 18 wheeler. These trucks turn much better when you off the throttle. If your trying to get it to turn better when doing these try moving some weight forward.
