The gounch bumpers are conical shaped rubber devices (think stacked
donut shaped rings of decreasing diameters) that are mounted on the
frame above the rear axle. Their function is to provide a cushion
between the axle and the frame if the vehicle goes over a huge bump
and the rear shocks are toast.

I asked the guy in the parts department how the word was spelled so I
assume it is correct.

I think you either misunderstood him or he was having some fun at your
expense. The part I was talking about in the struts serves the same
exact purpose as the part you described on the rear axle. "Gounch" is
not a word. "Jounce" is.
