It sounds to me like the Main Gear has a bit of toe-out. Have
a good A&P check this out for you. Toe-in (a little) is ok, as it
improves tracking, but toe-out (any) is right out, as it causes
divergance.  With toe-in the leading wheel has more drag on the
Runway , with toe-out the trailing wheel has more drag.
