It is logical that if you set all q's to zero and the configuration is the nominal configuration that $u_2$ should be zero. There would be no lateral velocity at either tire contact. I wonder if the limit of nonholonomic constraint as q_7 -> 0 gives zero for u_2.
The time derivative of the holonomic constraint gives you an equation that looks like:
If u4 and u7 are taken as independent speeds then you subtract and divide by f2.
More specifically, if q4,q7=0 then f1 and f3 become zero.
The other two no-slop constraints
u1, u2, u5, u6 u1, u2, u3, u4, u5, u8
You can see the divide by the sin(q7) here:
Or more clearly:
