We got the front driveshaft disassembled to check the splines prior to buying rebuild parts. There is not a lot of information on the web about how to check the slip joints on our drive shafts. So I sent an e-mail to Tom Woods with some questions, I have never dealt with him before, but have heard only good things. Not surprisingly he got right back to me with some advice. To check splines, disassemble the joint, clean it, then reassemble and check for play, more than .008" of play may cause vibrations. Ours is tight with only a few thousandths of play. So maybe a candidate to rebuild.
