Persistent Pull to the Left

[Maver1ck]

I am struggling to diagnose and repair a persistent pull to the left on my '68 Kombi. For as long as I have owned the car (6 years as my daily driver) it has driven perfectly straight, until recently.

About 3 months ago, I replaced all suspension bushings on the entire car, front and rear. A few weeks after that, out of nowhere, I got a serious pull to the left. Strong enough that I need to actively steer to the right about 20 degrees, and with some effort, to keep the car going straight. If I were to let go of the steering wheel I would be in the ditch in one second flat.

When the pull first occurred, I took it to an alignment shop. They noted the front left wheel had almost 2 degrees positive camber and they suspected my bearing was bad. At the same time, it appeared at least one of my front calipers was partially frozen. So, to remove all doubt, I replaced both hub/rotors, calipers, pads, and bearings. I also installed new front springs at the same time. Every single tie rod end and ball joint was checked. I rotated the tires. I ensured each was exactly at 30 PSI.

And still, the pull persisted. When I returned to the alignment shop, the camber was still 2 degrees positive. So I showed them how to use shims on the upper A-arm to bring the camber back to zero. The alignment computer said "all good!" yet it still pulls to the left.

I have just today deconstructed and reconstructed the entire front left suspension (removing and inspecting both A-arms and bushings to see if one had already collapsed or if the A-arms were visibly bent or is something was not torqued properly (nope). I thoroughly inspected the cross member / shock tower for any indicated whatsoever of a crack or bend. Nothing.

The brakes do not affect the pull at all. Rear brakes have been adjusted to perfection and front brakes are all brand new.

I am at the end of my diagnostic skill level. Any ideas on where to go from here (aside from the ditch)?
