Bob:
I know the corner you mention and yes, very good thing you were moving slowly and just dented the snowbank. Those banks eat plastic car body parts, but obviously can't digest WW2 Canadian steel!
The Regiment de Hull had CJ7 Jeeps between the retirement of the M38A1 and M151A2 1/4 tons, and the arrival of the Iltis. One of their folklore stories was how a "CJ" broke its steering linkage on the big bridge over the St Lawrence River enroute to Valcartier. The vehicle damn near pitched over the guardrails with three soldiers inside.
I suspect "the boys" had been 4-wheeling at some point and applied an adundance of gravity to the front end. Those were peppy vehicles that could chirp the tires in all gears.
