Those bottom nuts on the rear droplinks are ridiculous. Fortunately when I changed mine I was also fitting a bigger arb, so I just took everything off as one. To this day the old plastic drop links are still bolted to the standard rear arb!
Yeah the ball joint nuts are a bit of a joke. I went ahead and did the other side today, and again the ball joint nut decided it was going to be an ***. I thought it was coming off, and then it just cross threaded itself. So, once again the nut splitter was put into action. I’m just glad all nuts and bolts are going back on again.
