Been riding on prayers the past year and a 1/2 to 2 years that my axle wasn't going to give up on me. I don't drive the K5 except to hunt out of anymore, but due to the yoke on the stock rear being extremely loose, I was going through u-joints like crazy. I bit the bullet and bought this one on ebay today http://cgi.ebay.com/ebaymotors/NEW-14-bolt-rear-4-56-detroit-disc-brakes-dana-60_W0QQitemZ8058648126QQcategoryZ33731QQssPageNameZWDVWQQrdZ1QQcmdZViewItem all my overtime is paying off I guess I plan to swap rears, and just unhook the front shaft until I can get a 60 for up front since the gears are differant. ( hopefully have it by hunting season)...going to just get some el cheapo 8 lug rims and keep the same 33" tires until then. Anything I need to know about the swap? been reading the articles on tech, but I've never done it before. Wheres a good place on lineto get some new u-bolts that will fit this axle? What about brakes? Do I need to buy a proportioning valve or something to get these to work? Line lock or other for an e-brake? Is that enuff questions?? Hell, I'm excited...I'll finally be able to drive the K5 without worrying about the rear end grenading on me.
