Two dynamic methods are compared for integrating the Reynolds equation as applied to determining the axial dynamics of a spool bearing. It is shown that very sensitive phase shifts in the numerical schemes can badly falsify the dynamics therefore, care is needed in interpreting results using classical methods. Second order temporal accuracy can alleviate these problems one such scheme is presented with excellent phase properties that is just as computationally efficient per time step as any of the first order accurate schemes.
