I'm replacing the tie rods and idler arm. Everything's off and I have all new parts to go in except the idler arm bolt which looks like this after soaking overnight.
It's not completely stripped. Having trouble finding a replacement, I found a self-locking nut that would work (on the left there), but I'm not sure if I should use it. What do I do? I won't be able to find a proper one until tuesday at the earliest!
This was the balljoint that was making all the noise I think. It was a megabitch to get off. The rest was pretty easy.
***- All of this was really helpful Ross - I actually did put one nut back on a bit too far and it spun like you said but I managed to get it off with skinny vice grips.
