I have searched the forum for a solution to no avail. If I missed it, please point me in the right direction. Here's the problem... Occasionally, when I come to a stop, the rear drive line make a horrendous sound, as if the drive line is in a bind. It only happens below 7 mph as I am decelerating. Other than coming to a stop, there is no vibration at all. A little history... I have a 74 40 with 2.5 OME lift, which sags in the rear a bit, (I have new Alcans on order) with extended shackles. I recently had a bad drive line vibration and actually lost a rear drive shaft due to incorrect angles. I now have the flanges shimmed within 2 degrees of each other, new u joints, no slop in the rear diff yoke, there is slop in the front diff yoke, which I plan on repairing soon. Any suggestions for a remedy? Any help would be appreciated!!! Thanks!
