As an fyi, I spoke with the maker of the Jackstrap and [ahem, assuming I got the story straight] they tested the strap using a well-lifted 5,500 lb Jeep with "really big tires".  Their test consisted of strapping the suspension down, jacking up the truck, and then jumping up and down inside the vehicle to see if anything broke.  The strap survived, but the hook apparently deflected a bit so they figured the strap was probably good for 5,000 lbs max.  Gotta love the tight labratory testing conditions - just add a case of beer and you've got yerself a pardy.  Here's a pic of their product.  They're about $30 each.  I'm hoping I can get the same thing accomplished with some chain and a grab hook.  Anyone actually tried this?

Wow, sounds just like Underwriters Laboratories, NOT. 

Give me a break!  That scares the hell ut of me.  The hook is securing the loadand any deflection is not a good thing.

I think we need an "axle hanging challenge" -- the ratchet strappers vs. the chainers. 

Old school Formula start -- teams sprint from 20 feet away to a closed truck, unload the jack and straps/chains, secure the axle, jack up the truck, change the tire, drop the truck and stow the gear.

Losers buy the post-challenge libations.
