every so often i go into a local river bottom and wheel with my friends. the sand here is nothing like pismo sand, this is course, soft and slippery sand. my main concern is when i turn my truck (67 long bed, dana60 front...) the wheels shake voilently left to right. reminds me of axle wrap/wheel hop, but it does it side to side. it does this only when i turn so sharp, it doen't do it if i barely turn. my steering is perfect on the road. i have a new stabilzer too. i have a fairly new crossover steering. my d60 is also a posi traction, would this cause the shaking. it is a shake too, not a vibrate, i can actually see my wheels shaking! i'm stumped...i dont think it did this is pismo but that was about a year ago.
