rear trailing arm ball stud sway bar mount
 

Does anyone know if the one piece ball stud that the rear swaybar attaches to in the trailing arm unscrews out of the trailing arm????? any ifo would be greatly appreciated.

The stud isnt threaded, The tapered ball stud is an interference fit into the trailing arm. Perhaps there is a spot or rosette weld holding it in place.

thanks tim

I came across this when trying how to make late 21mm sway bars work with my ball-joint rear arms.

I gave up any idea of removing the ball-joint in the arm and had a droplink fabricated that essentially links the plastic ball socket at the top, to a rose-joint that bolts to the sway bar at the bottom.

The rose joint is threaded so the whole thing is adjustable.

some guy saw it off and then taps a hole where the ball stud used to be.

alfizzo,

It would help to know what year control arm you are asking about! The '67 - '73 steel arms are DEFINITELY WELDED! The '74 and later aluminum control arms are a different case.

77 911 trailing arm.

If its anything like the trailing arm on my 78 that I pulled off just last night, there is a bolt that secures the link to the arm.

So what did the solution end up being. I have a '74 911 here with aluminum trailing ams and am also putting the later style 21 mm sway bar on. I have broken one of the balls off since I assumed all of them unscrewed and I really laid into it with the pipe wrench. Does the Ball mount press in? Can I pull it out then tap the hole? PLEASE HELP. this sucks

I never got mine out and couldn't find anyone who has, hence my fabricated rear drop-link.

Can you clean up the broken face, then drill it and tap it as suggested in one of the links above?
