I have the 2 piece driveshaft. Well, I noticed that the driveshaft support, which is a bearing that connects the two pieces has dry rotted. I thought I had a problem with my clutch at first, since it felt like it was slipping. Couldn't really make it up a small inclined driveway and every time I hit a bump in the road my engine would rev. Even starting out I have to feather the gas until I finally get into gear. I recently put blocks in the rear and my axle shifted on me. I'm thinking that the front and rear drive shaft have moved and that is causing me to not fully engage into gear. The center support is about $250, so is a new clutch, which should I try first? Or is there a one piece drive shaft for my 99 4wd v6?
