So after not having a spare or a jack for that matter for the last two years, I think it's time for me to stop living on the edge. I noticed that Ford lists a 4X2 and a 4X4 jack, both with the same lift capacity (and same number on their parts diagram). However, the 4X2 model is 1/3 of the cost. Is there really any difference between the two that won't allow me to use the 4X2 model on my 4X4 truck? I can't really justify $250 for a spare tire jack when I can just get a cheap Crapsman jack and throw it in the bed. My truck is a 95 F-150 4X4.
