On my Dads old 1 ton Bvan, We put so many in that ol girl that we eventually basically ruined the upper control arms and the threads were no good, I know they really arent threaded, they are a self wedge type thread, so if you are to nasty with it you can over swedge the control arm and ruin it. We ended up tightening them as good as possible and running a 1/4" long weld on the tops as a bandade since we didnt have a control arm and needed the van ASAP.

As far as I know they are still on it. My uncle owns the van now, and he dosnt use it like Dad did so they will last a while yet.

My socket is beaten up pretty badly, and I have had to weld a hunk of square stock in the 3/4 hole fromit being rounded to far for a breaker bar to work. Now I use a 3/4 square drive impact socket, and my BIG snappy Impact.

Buzzes them right off.
