This is all you need to remove the nuts in the engine compartment.

I'm on the right side, and I've tried every tool I have to get in there ; it's a MFer. The u-channel that the nuts sit in makes it extremely tough to access them, and the closeness of the motor makes it impossible for me to get a socket on. I'd love to see pics of how you're using the tools you use; maybe I'm just not going at it from the correct angle.
Is there a hex inside the end of the ball joint stud?
On my VW (not the 928, as I haven't done it's suspension yet...) there is an inside hex that you can put a wrench into to hold the stud while torquing the nut.
Semi-retired, as of Feb 1, 2023.
The days of free technical advice are over.
Free consultations will no longer be available.
Will still be in the shop, isolated and exclusively working on project cars, developmental work and products, engines and transmissions.
Have fun with your 928's people!
.....I spent years begging someone to make this wrench.
I was sent this one, as a testing prototype.
It's the "bomb" for upper control arm nuts.
Works really well to loosen those 200nm rear suspension camber eccentrics, too!
Not sure if they are available to the general public, yet, but I've had mine for a couple of years, now.
Folks were telling me how easy it is to get those nuts but I found it was a sod of a job. I managed to get the driver's side rear most nut from the top and for the others I had to move the ac compressor, the alternator and the power steering console out of the way. Not that bad considering I also was doing the PS hoses and the engine harness at the same time.
Does that wrench enable you to get all 4 nuts from the top side?

Are you trying to do this with the ac compressor in situ?
I by no means claim to be an expert here, but maybe this can help someone. I recorded changing the one side on my car. I was able to use a socket on one nut and I believe an open ended wrench on the other. For the balljoint nut I used a breaker bar or a crowbar to put force downward on the a arm to be able to tighten the nut without turning the joint.
Kudos to Mark @ 928Intl who sourced these parts in Europe and supplies me with them. They are better than new.
We also have lower control arms of the same quality. We are all lucky to be part of this great 928 community.

Are you trying to do this with the ac compressor in situ?
Yes, but as it turns out that wasn't a problem, but it was a hint.
I've been trying to go at it from the top. I went at it from the bottom, angling up from near the compressor and I was able to get first the 1/2" 22mm breaker, and then the 3/8" 22mm ratchet on there and they are free. From that angle I'm actually able to get my hands up there, so I can spin the bolts back on when I get the replacement A arm.

I ran out there yesterday to check, great idea, but no, just a round indentation and nothing to get purchase on.

Great video, that will help others down the road. Thanks for posting.
I tried that method and still couldn’t get the final torque to happen so there’s still like a mm of space between the steering knuckle and the nut. It feels good though, I guess I will drive it and check it after to see if it sets more.

Thanks Mark, I didn’t realize it was the same source. Good stuff.

Hmmmph...no such animal exists on google. At the suggestion of Rennlist 928, I bought the MTNRM6 set of Mountain double box flexible reversible ratchet wrenches a few years ago. Worth every penny. The 17/19 was the only thing that would get good purchase and break the bellhousing bolts loose. I would LOVE the 20/22 wrench!
The wrench in the photo appears to have a Monster logo, and they indeed do make a set of them. Unfortunately their website (monster-tools.com) is next to worthless, and makes me think they are rebranding someone else's production.
Martin, I have the MTNRM6 set of metric wrenches, which includes the 8/10, 12/14, 13/15, 16/18, and 17/19 wrenches. I have been unable to find any reference to the 20/22, other than Greg's post.
