In my experience, the rear spring is rarely the cause of leaning to the
drivers side, though I can think of one or two instances where it has proven
to be the case. In most instances the lean is caused by other factors - wear
in the rear spring pad, twisted front anti roll bar and generally tired
front suspension are more common factors. The lean is more apparent with the
swing spring cars because of the lower roll stiffness of that arrangement -
the spring "allows" the car to sit at an angle whereas the rigidly mounted
spring fights against the lean.
Just my observations of working on these cars, ymmv,
Cheers,
Bill.
