Hi, I have a 90 full size which a bought a few months ago and I have just switched out the rims for something similar to original. I have an issue with my passenger side lug posts. 2 of the 5 are loose. They dont seem to want to bite on the back end and I cant seem to tighten them down, they are just spinning. (posts) I am using closed end nuts and I thought maybe I could try open end to grab hold of the lug post to stop it spinning? I really dont want to pull things apart being its got the 4wd locks just to get to the back of the post. I have no idea what these posts look like on the back end, but I know they aren't broken. Any suggestions would be greatly appreciated.
