4.8is alignment driver side rear issue

[nextelbuddy]

So I'm on a long what feels like 2 to 3-year journey to figure out why I cannot get my driver rear camber any better than negative 2.6 My passenger rear is no problem. We can go down as low as negative 1.6 with the stock eccentric bolts.

Things I have replaced:

- 20 piece lemforder suspension kit front and rear including the rosebud ball joint bushing on the rear suspension arm including new camber and toe arms
- replaced all four lower swingarm/control arm bushings with poly bushings

- new arnott air springs front and rear (running correct comfort rear springs for 4.8is with dual Axle air suspension per real oem)


I believe something is bent on the driver side rear but I can't figure out what because everything visually looks fine but I know it doesn't take much to throw even half degree to one degree.

We even tried using ratchet straps to pull the lower swing arms together and we pulled out the camber eccentric bolt and welded more material to achieve more positive camber and still could not get the driver side rear with inspec.

You will see in the pictures below and you can see with the eccentric bolt pulled out even with said at max positive camber on the eccentric bolt when it is pulled and everything held in place with ratchet straps. There is still a lot of room for that swing arm to come in even more, which means something is not right in the rear driver side suspension

Does anybody else have any experience on what could be bent causing me not to achieve more positive camber on the rear driver side?

I have silver project rear adjustable camber and toe arms but I can't use those. I've already removed them because when I use them to achieve more positive camber I can go as low as negative 1.5. however, that causes the rear air spring to interfere with the inner body cavity which causes air suspension issues so I had to remove them to reinstall the stock parts. Unfortunately the way the silver project or any rear adjustable camber arm work on these cars, They pivot the suspension in a different area causing geometry to change in a different way, which isn't an issue if you're on a rear coil setup but it does cause an issue with the rear air spring set up.
