Yeah so I was driving to work this morning when the guy driving in front of me stopped short at a red light, so I hit the brakes too. I thought I didn't hit them hard enough to lock up the brakes but it felt like the rear locked up on me. So then as I am trying to stop I hear a ton of popping and banging. So when the light turned green, I hit the gas and the engine just reved. So I thought I broke an axel shaft or something, so with people honking behind me, I looked under the truck to find out that my driveshaft had come off the tailshaft of the t-case and it was still securely fastened to the differential. So, luckly I had my tools with me and I unbolted the driveshaft in the middle of traffic and I drove back home in 4 wheel drive. This one has me a little stumped , how did this happen? Does axel wrap happen when braking too? because I didn't think it did. Also now since the driveshaft is out I thought I'd replace the u-joints, and I have never done that before and Hilton's repair manual is only for a different type of u-joint and is no help any way. So how do I get the old one out and the new one in?
