Car pulls on acceleration

[Kyngfish]

Just did a full suspension refresh on my 1987 W124. The entire subframe came out and I did all of the bushings, links, control arms, brakes, rotors, springs and shocks. For the front, I did new springs and shocks, new control arms/ ball joints, with their matching bushings, new pads and rotors, and new sway bar bushings. Put it all back together and got it aligned. When out on the highway, I noticed that under acceleration, the car would sort of drift to the left, then when I got off the gas, it would come back to the right, so I got under the car and checked all the torque specs and took it out and drove it again. Same issue.

So this time I placed jack stands at the center of each wheel hub and measured the distance on either side. One front wheel looks to be about a half inch further forward than the other, so my guess is that either they didn’t know what they were doing when they set the caster or the new suspension is still settling and it has changed. When I checked the bolts in the front control arm, the adjustment bolts were definitely looser than they should have been on the driver’s side, so who knows what happened.. As I was trying to avoid - the likely scenario is that I’ll have to do the caster myself. I imagine there isn’t a full half inch of adjustment and that I’ll have to adjust one wheel forward and one wheel back.

Just wondering if anyone has ever experienced this drifting issue and whether the caster is the likely culprit, or I should look elsewhere.
