what size sway bar bushings do i need?

I have a 2000 Cherokee classic 2WD and I I don't know what size sway bar bushings I need... please help. Thanks!

You will have to measure the sway bar diameter, as there are several different sizes.

Grab an open end wrench or an adjustable wrench. The smallest open end that fits over the bar is the size you need. If you don't have wrenches that big, but have an adjustable that size, tighten the adjustable to fit the bar, remove it, and measure the opening. Poor man's calipers.
