Yeah mine does the same thing. I have posi on the rear axle and the
slightest touch on the gas pedal on a slick surface starts the rear wheels
spinning. They spin real good on dry pavement too <grin>.
One time, I got stuck playing around on some ice where the water had frozen
on a parking lot. I couldn't move, because the rear wheels were spinning
even at idle. I had to push the emergency brake down about two of three
clicks to put just enough brake pressure on the rear wheels to stop the spin
and let power go to the front axle.
I have had to use this emergency brake trick twice, when I got stuck in
extra soft sand on the beach. I got stuck then because I took my foot out of
it and the tires sunk. I don't know if this trick will work in mud or not.
It should, but I don't take my beautiful Chevy in mud, that is what my old
rusted out Bronco is for.
