Timoz      Timoz New Member       just receintly shortly after
engaging toe/haul option the auto 4wd (which I always leave in
2wd) seems to shift between 2wd and 4wd high and I can hear the
gears grinding as if not fully engaged. I can press the 2wd
button and this wil stop. How is this happening?    Share This
