So I've got an 05 ram 1500 quad cab long bed. I suspect u-joints, vibration at anything over 45mph or so. sometimes I can hear it start at lower speeds, and sometimes its hardly noticable. 2 piece driveshaft. Truck had a 3" lift, back half of the shaft was at a bad angle. My question is, am I able to unbolt it from the diff and just drop the rear portion of the driveshaft out to replace the center and rear joints? And if so are there any markings on the slip joints to get it back in where it was before?
