V8 Jeep vs. Big Block Bronco

My buddy just got his 94' Jeep running again so we went out to one of the local wheeling spots and shredded some hills for a while. We should have filmed some of the hills and trails earlier in the day before I decided to break another ujoint and axle shaft (you can hear it pretty good in the video) big power and a full spool don't play too well on a baby Dana 44. The YJ has a mostly stock high output 5.0l out of a mustang and the bronco has a built 429 that is well over 400hp.
