I've got a 97' reg cab long box with a 3.9 5 speed 2wd. Theres been a lot of clunking noises coming from the truck, I've been told it's the driveshaft u-joints (theres three of them) from the transmission to the rear diff along the shaft. I've got a bit of mechanical experience, but nothing major. Just wondering if anyone can give me some pointers about the process of replacing the u-joints. Any help would be greatly appreciated, I really don't want to drop several bills at a garage if its something I can handle. Thanks in advance, Jerrot!
