  We study the phenomenology of heavy gauge bosons at the LHC in a nonuniversal
gauge interaction model with the separate electroweak SU(2) gauge group for the
third generation. Considered are the Drell-Yan processes into the final states
of dilepton, dijet, $\tau^- \tau^+$, and $t \bar{t}$ for $Z'$ boson and those
of lepton-neutrino for $W'$ boson. We find that the present LHC data provides
lower bounds on the masses of the heavy gauge bosons, $m_{Z'},~m_{W'} > 2$ TeV,
more stringent than indirect bounds, when $\sin^2 \phi > 0.15$ for the mixing
angle of two SU(2) gauge groups.We also note that the study of heavy resonances
into the third generation fermions may provide some valuable information in the
future.
