Steering Question

On a 77 Diplomat.....
While moving if I steer to the Right all seems normal.
If I turn "left" it is VERY easy way too easy.
It is so easy I have swerved a few times while cruising around 60 MPH.
Why would One direction verses the other be so different?
If I lift the Front wheels Off the ground it seems to be about the same effort.
it does NOT auto steer Left or right it stays where its at.
Any Ideas?
