3 or 4 groove pitman arm - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Good day all. Have a quick question that maybe the collective mind can help me with. I have an 05 Silverado Z-71 4wd Ext cab. My pitman arm is a little worn. When looking for a replacment I am given 2 options. A 3 groove or a 4 groove. I cannot see the grooves from under the truck. Just trying to see if there is any other way to identify which one I have with out tearing the truck apart. This is my daily. May try and remove the nut and see.

Thanks
Phil

Thanks for the reply. replaced it this weekend. It was a 4 groove arm. Not as bad as I thought it would be cause of the frame design.
