Stabilizer bar cracked???

I was getting things ready to replace my front shocks and noticed that my stab bar is cracked in the middle where it attaches to my lower A-arm on the passenger side. Has anyone else had this issue? Do I have to replace it or can I drive the van with it cracked? I had not felt any difference in driving prior to noticing it cracked.

Is it the stabilizer bar or the end link that's broken? The end link connects to the stabilizer bar on one end and to the control arm on the other. Basically it's a 3/8 x 16 bolt about 6" long with 4 rubber insulators, 4 washers, a spacer and a nut. Most auto parts stores have them http://shop.advanceautoparts.com/webapp/wcs/stores/servlet/product_Suspension-Stabilizer-Bar-Link-Complete-Autopart-International_24012613-P_78_R%7CGRPCHASAMS_1024053490___

The actual bar. It flattens out on the end and has a hole where the bolt attaches. If you look at the top to see the hole it looks perfect, if you look at it from the side you can see it cracked. I have never seen them crack like that!

Here's a link to a Dorman part that most any parts store can get. Just give 'em the Dorman number. If Dorman makes it, you can bet it's a common problem. http://shop.advanceautoparts.com/webapp/wcs/stores/servlet/product_Suspension-Stabilizer-Bar-Dorman---OE-Solutions_25989514-P_1414_R%7CGRPCHASAMS_831886537___
