Draglink center link issues

[Robznob11]

I hope this is helpful info for others with wandering truck syndrome. It has been stated many times that installing the drag link backwards will caus wandering. Well assumption of parts will too! Always remember these trucks have been around long , sometimes longer than we have. Never assume you are dealing with stock untouched equipment even though it may look that way. I just finished my truck after a 18 year build. I have all new front end with porterbuilt arms. Only stock part is the drag link. Now... when I bought the truck years ago it had drums. Back then I converted to disc and bought cpp conversion adjusters and ran 68 outers as inners and 72 outters in their correct location. Remember now ....this was done when I was about 23....the project took 18 years to complete before I could actually drive it. Now back then I learned then that the tie rods were different. 72 disc have 11/16 threads and 10* tapper. Earlier drums had 5/8 threads and 7* tapper. I knew that the drag links were different to match the said tierod. So all these years later I get the truck up and going and no matter what I could not get it to quit wandering. I checked the direction of the drag link it was correct. But I failed to check the obvious!! You see I assumed since it was drums when I got it...it just be a stock 68 drag link.WRONG!!!!
Some unknowing knucklehead had changed it before I got it.
Only thing I can think is that back when I was younger I did not pay attention and just saw that the new rod ends were the same size as the old and stuck them on. It really is embarrassing to think that I know this truck inside and out and I knew full well of the many changes in parts GM made, but because I thought I already knew I chose not to check the obvious!
So as advice....If its wandering and the drag link is on correct. Even if you have brand new parts. Check to make sure you did not overlook and obvious issue that some fella before you left for you to figure out!
