Tonight I was stopped at a stop sign about to turn right and when I pushed the gas my blazer kindove lurched and a loud bang occured, I jump out look under the truck and there is no driveshaft I turn around and there it is a about 6ft away I look at it and both u-joints were broke off at the caps, Luckly I was about a 1/4 mile away from my house so I drove home in 4wd with tranny fluid pooring out, WHAT COULD HAVE CAUSED THIS????? Next question is what u-joint is in a rear driveshaft out of a 1985 blazer with a 208 t-case and a 10b rear?? Much thanks. -Chris P.S: I will have carnage pics tomorrow!!!
