1998 GMC Jimmy

As Mike says, one BFH - I find 4 pounds is usually adequate, myself

Tools: buy or borrow a pickle fork for unseating the ball joints. They also make a smaller size for tie rod ends. These are cheap but many parts stores have a loaner tool program for such things. You may also need spring compressor for the coil springs - seems to me I needed that on a GM car but it's been a while so I may be remembering wrong - and the taller the jacks stands the better as that gives you a better swing with the hammer.

I would also second the suggestion to check the tie rod ends and all the other moving parts before you start. With the price of a decent alignment anymore, you might as well replace whatever is questionable and just have the alignment done once.
