The Jeep I bought has no jack I need to know what it looks like so I can get the right one. Can anyone post a picture?

Go nab one from a Junkyard or buy a cheap floor jack to throw in the back. They are a small bottle jack about 8 inches tall. Most common one that you have ever seen.

x2...the stock jack IMO is a PITA. it is a crank up bottle jack. a cheap hydraulic bottle jack would be much nicer, faster easier to use and keep centered when jacking it up. however it is much easier just to have a floor jack.

just takes up more room but very nice when you need it for sure

you could also use a hi-lift jack and mount it on your bumper or something. and is nice if you are going to lift your jeep more than 4 inches.

That's what I plan on getting...
