I went for an alignment after doing the figs rear knuckle bushings and the alignment guy said the stopper isn’t touching the alignment washer so he couldn’t get it 100%. I attached a photo of the rear camber bolt for reference. I couldn’t get a good pic of the rear toe adjustment washer but it’s the one he is pointing to. It has a lot more space then the rear camber adjustment between the washer and stopper, about 1/2”. Should it be touching the stopper?

 

Regarding the rear lower control arm (LCA) adjustment, below is a photo of my stock GS400 rear LCA, showing the inner and outer cam guides on each side. The adjustment cams ride between these two guide features. From you photo, it appears that you are missing the 2 tabs at the end of your LCA. If so, welding on new fabricated tabs should be an easy job.


Each side of the rear LCA has 2 guide features that the adjustment cams ride in.

From your photo of the toe adjustment cam, I believe you are having the same trouble I had. The 2 "inner" cam guides (the semi-circular tabs) on each side of the toe arm mount protrude from an unsupported, cantilevered sheetmetal boss. When the adjustment cam is rotated, it rides against the "outer" tab on one side, and this "inner" cam guide on the other side. The normal force of the cams pushing on the "inner" cam guides cause them to bend inward, and out of plane, where they no longer bear on the cams. The OEM bushing somewhat helps support the the 2 outer cam guides as they deflect. I had to open the mount bosses with a hydraulic spreader to fit my Figs toe links. I then welded a thin bar across the semi-circular tabs, so that they no longer deflect inward. I then installed Figs toe lock-out plates; a much different rabbit hole!
Even if your inner cam guides are not deflecting inward, make sure the cams are fully seated against it. In your photo, it appears that one of the cams (2 per side) is sitting ON the inner cam guide.

wow thanks for the info. I had no idea there was supposed to be a guide on the end of the LCA as well. Mine appear flat and they are oem. Would they flatten over time? Not even sure how that’s possible. Do you think my situation would cause my rear alignment to not stay put? I am going to have my friend redo the rear toe arms and adjust the rear so it touches the guides. Not sure how I can bend those ends of my LCA properly though. Any suggestions? This is probably why my rear alignment doesn’t stay put

 

I think it’s the angle of the pic. Here is another angle where the guide touches on the bottom portion


I have to get a better pic of the rear toe arm. Maybe it’s the angle but mechanic mentioned it wasn’t touching the guide. But I don’t see the end protruding like your photos

here is the other side after figs knuckles were installed. You can see it better touching the guide. So I think I just have to worry about the rear toe arms.

 

Looking at my pics it does seem one side is sitting higher. Do you think that’s a problem? Here’s both sides after installing figs
