  We construct anomaly-free leptophobic U(1)' flavor models with light Z'(~ 145
GeV). In order to allow renormalizable Yukawa interactions for the standard
model chiral fermions, new Higgs doublets with nonzero U(1)' charges are
introduced. Then the neutral (pseudo)scalar Higgs bosons as well as Z'
contribute to the t\bar{t} and the same sign top pair productions
[\sigma(t\bar{t}]) and \sigma(tt)], and one can evade the strong constraint
from \sigma(tt). The top forward-backward asymmetry (A_{FB}) and Wjj excess at
CDF could be accommodated by A_{FB}^{New} = 0.084 ~ 0.12 and \sigma(W j j)
\lesssim O(10) pb \times \sin^2 2 \beta.
