  Randall-Sundrum scenario with all the standard model (SM) fermions and gauge
bosons in the bulk is phenomenologically studied. Even though the simple
assumption of universal bulk fermion mass m_\psi leads to the same Kaluza-Klein
(KK) mass spectrum for all the SM fermions and thus suppresses new
contributions to Flavor-Changing-Neutral-Current and the \rho parameter, large
Yukawa coupling of the top quark generates its KK mode mixing and breaks the
degeneracy: unacceptably large contribution to \Delta \rho occurs. With a
different bulk fermion mass to SU(2) singlet bottom quark, we demonstrate that
there exists some parameter space to satisfy the \Delta \rho constraint.
