  We present simulations of relativistic jets propagating in a nonuniform
medium. Specifically, we study the bending of jets propagating obliquely to the
vector of the density-gradient. Our results are applied to the NGC 4258, where
such a medium is assumed to be provided by the atmosphere of the sub-parsec
accretion disk tilted with respect to the original direction of the jet
propagation. As a result, the jet is bent on a scale comparable to the density
scaleheight of the disk atmosphere. The magnitude of the bending effect is
found to be largest for light jets with low Lorentz factors. The predicted
direction of bending is consistent with the observations.
