Front upper control arm bushing torque spec

I will be doing mine also soon because of bad ball joints. I think I will fixture the old one and get a measurement so I can duplicate what is there. I also did not know that they come with the bushings loose.

Not a good idea...perhaps with the new shocks..bushings etc...the front corner of the car lifted on the max jack. No way was it going to compress and move the A arm up.....it moved a little bit not near enough.
So... I will try it again later when the car is on the ground.

For the record...there really needs to be a note saying so. I just happened to notice when I was checking a wheel bearing I had adjusted And could hear a clicking. I had no idea either to be honest.

Crows foot...you can get it 90 degrees...if not it’s only about an inch longer from the center of rotation , so it’s close enough for government work as they say. (Or you can do the physics/math and adjust your wrench a few pounds)

I puzzled over the torque for these bushing pivot shaft end nuts as well as the arm position when you tighten the nuts. All I know is that my original arms, which had never been touched, sat horizontal when the ball joint was removed. So I would set replacements like that. Also, I can tell you these arms probably will not take much more than 63 ft lbs. The threaded part of the shaft begins to stretch somewhere around 80 ft lbs. Don't ask me how I know.

Good to know...not much difference in feel between 60+(Spec) and 80 ft lbs..unless you get a torque wrench on it. Not a few nuts you want to “just “ tighten.

Bonjour,
I do not remember what torque I put on the nut when I changed the upper control arm. But after few thousand miles... one is completely loose... and all others unscrew... I had the good idea to put torque seal on them...
So I will tight them now at 85Nm and keep an eye on them.
Cheers,

Remove the front wheels. Wooden blocks under the step in the rotor. Lower car onto wooden blocks.
Be careful that the wooden blocks don't slip! (Don't put body parts under car.)
Alteratively, I've got old BBS/machined out 911 Fuchs centers that we bolt onto the wheel studs and set the car down on these.
Safer!
