W108 listing to port

My 1970 280 SE base model sedan is undergoing a refurbishment to make it a daily driver.
ALL suspension rubber has been replaced, installed a hydronuematic compensator, replaced all coil springs and had the rear axle removed and replaced so a full boot could be installed. After five miles of driving and a visit to the alignment shop (with new tires) the rear camber is +2.1 left and +1.6 right and the whole car sits almost 1 CM higher on the right.
Spring pads and springs are all equal.
Taking suggestions.
Thanks ahead.
Brad

What is the spec for rear camber?

It may take a few miles for everything to settle in after that much work.

What is the height of front tire to top of wheel wells?

After driving for a while you may need different thickness rubber spring pads.

did you also replace the front subframe mounts?

My thought as well. But begs the question, how were the cars not not right when new?

I will find out. But the car is almost 1cm higher on the right in the front and the back.

Springs were equal length front and rear.

I think when there is a complete rebuild on older cars it sometimes just doesnt come out the same for unknown reason. My W126 after complete front end rebuild could not get the camber alignment in spec. Car pulled to side at higher speeds, After 6 months of driving it seems to track much straighter now. I was equally baffled why all new parts did not guarantee in spec alignment.


If both front and back are higher then it could be both front and rear that need spring shim adjustments?????

It's amazing to me but after studying the Big Blue Book there is no mention of what to do if the rear end is too high. They do acknowledge that the camber could be different as you are supposed to use an average.
Because I am using a Hydro compensator I am concerned that the car not be using the compensator to give it it's height. Thinking of putting in the spring I took out and comparing results.
If the Hydro is pushing up the car then the pads won't make any difference.
I am also looking at the carrier of the rear axle suspension as possible culprits for listing. Since it was R&R'd to renew rubber it may not have been installed correctly.

They didn't have 49 years of listing, bumping, twisting, and other gradual deformation when they were new.

Is the hydro too long or are the spring pads too thick.

Overall rear camber is adjusted by adding or substructing shims between compensator ball joint and stem.

There are no added shims and the left hand ball bolt is not the extra long one.
UPDATE: Put the compensator spring back in and changed the upper spring pads to the thinner one on the high side. Car now is less than 1/4 in. higher on the right and the camber is overall less.
Next step is to drive car 100 or so miles and measure. If camber is within spec with compensator spring at curb weight plus 220 lbs then I will replace spring with hydro and see where we end up at curb +220 lbs.

I understand that you are trying to make in perfect. However in 70' those things run on 185 SR75 tires. 1 degree of camber would not make any difference in handling or tire wear.
