my fiance's uncle blew his 9" ford and an axle shaft on his Dana 44 in his 79 bronco doing what I would call moderate wheeling no full throttle it was slow rock crawling. it had a 351 with a manual and 35's.

Now since the isuzu's are pretty gutless unless you swap motors how can you bust axles with no power.
