Did some wheeling down some sand quad trails today and decided to try the ATRAC system out. After doing a tight right turn (slider on stump and pivoted on the slider) I started getting a metallic thumping sound out of the driver side wheel area. The sound wasn't consistent as it would thump twice quickly, then go 10 feet before thumping again, then again in 3 feet... etc. It did it regardless of whether the truck was under power or coasting (clutch in).
The noise went away after going into 4H for a bit and didn't come back when I went back into 4L.
Anyway, two questions....
1) Should I avoid turning/sharp turning when using ATRAC?
2) Any idea on what the noise is? I did an inspection and couldn't see anything visually wrong, nor could I see any trees/debris hanging off the truck.
