It seems the issues come in bunches. I wrote earlier re shakes. Here is my new issue. The truck has started making a clunking sound when I put it into drive. I repeated this several times in the drive and my leveling system light, ABS light and several others came on. When I turned it off the battery was dead. This happened to my wife the night before. It has been making this noise for a couple of weeks. I just had time to look at it. Any ideas? 99 DII. 88,000 miles. It has done this before when I had it hooked to a boat and self leveling system operated. Had to jump it off then to. Put new battery in a little over a year ago. Perhaps a short in system somewhere? Maybe these details will help.
