Back in November of 2011, while I was in the process of changing my oil, I discovered the shift linkage between the lever and my transfer case on my 2005 Dodge Ram 1500 4x4 had fallen off. Upon looking into it, I found the dealership fix would be $40 for parts and I can install them myself. Since the grommets wore out once, I am sure they would do so in the future. Not wanting to do this again, I began looking for a permanent fix. In searching the internet, I came to dodgeforums.com and found many threads with the same issue. I found a fix by one of the users on this site, but it involved shaping a piece of steel to fit, so it was put on the back burner until I found someone with the tools to shape the metal or found a different fix. Today, 01/14/2012, I found a way to fix it and with parts all from Lowes. I am including the part numbers I used, as well as a diagram of how they are arranged when installed and a picture of the completed instalation. The price listed for the parts are for the total. Total time to install might be around 30 minutes tops.

Tools needed:
A 3/4" box end wrench, a 3/4" socket, a ratchet, and a short extension for the ratchet.

Parts Total: $11.25 (This value doesn't reflect the price with tax because I had to make a few trips inside to swap parts out before getting it right.)

Since the turnbuckle can be adjusted, I won't tell you what length to set it at. Just adjust it as needed. I put everything together before crawling under my truck. Then it was a simple matter of unscrewing the lock nut and then pulling washers off, threading the bolt & spacer through the hole in the transfer case connection, then putting the washers back on the bolt and hand tightening the lock nut. Then I repeated the same procedure on the shift lever, but flipped the direction the bolt is facing. This must be done so that you can shift into 4 low. Running the bolts facing the same direction results in clearance issues with the transfer case housing. After both ends were connected, I got in my truck and checked to make sure the linkage was working right & it was, so I crawled abck under my truck and tightened the nuts & bolts with hand tools and that was that. While talking with one of the people working the hardware department, he advised me that the steel might pull the threads from the aluminum turnbuckle. While that might be a possibility, I don't forsee a problem with this, but I will check and see how it is holding up in a month.

I do hope this works for you. If not, it is at least a starting point.
