I have talked to the parts guy at the dealership, and for the 2007 and newer dana 30 only, the 2006 axle u-joints are the same part number as the 2007. I have gone to a local after market dealer and picked up some 06 precision super strengh u-joints. Installed no problem. Save lots of money compared to oem spicer.

 

I'll probably go with oem spicers. Mainly because I've got 65000 miles of trouble free service with them

 

The one I got are non-greasable, I believe you can get greasable. Its half the price of OEM

 

Your luckey, where I live, there is lots of salt on the roads in the winter and the OEM don't last. This is my 3rd set and this time I wanted something else than OEM. I have 62000km.

 

Dont buy ur u-joints from dealer, they charge a ridulous amount of money for them.
