I was under my truck today, looking at the starter, and noticed that my front drive line has a bit of slop in it. it has a constant velocity joint (2 u-joints together) at the transfer case end, a regular U joint at the front axel, and a slip yoke in the middle. I can get about a half inch of deflection at the slip yoke. Should I get ready to buy another one of these damn things? I've put 3 of them on my truck in the past 5 years. This is the first time it's been the slip yoke that has been questionable though. Always the CV joint before. Oh, by the way, it's a 83 1/2 ton with about 3" lift. Thanks guys.
