Over the years lots of people have gotten pulled out by a strap around the swaybar, a shackle, or an axle. If the pull isn't too hard, and if you're lucky, this will work. If you are REALLY stuck, or if you are unlucky, then you will do so much damage to your suspension that the cost of a set of proper tow hooks will look like pocket change.
Put quite bluntly, going wheeling without proper tow points front and rear is just STUPID!!! They are dirt cheap compared to the cost of the damage you can do pulling yourself out by hooking onto any suspension part.
Get real tow hooks, or a receiver hitch, for both the front and rear of your rig BEFORE you go 4-wheeling!!!
