Some guidance here would be helpful and appreciated:

On the rear of W126 cars, which adjustment controls the toe-in and toe-out (not camber)? And where exactly is it located?

On my vehicle, I believe that the wheels are somewhat toed-in, which could affect ride and handling. I do NOT have sag, or any camber problems. But I am curious about the toe adjustment.

Can anyone advise in detail? Thanks.
