The present application discloses a mechanism to adjust backlash in a rack and pinion powertrain assembly. The mechanism to adjust backlash includes a mounting frame having an opening defined therein to receive an operative end of a drive assembly, a shoulder fastener positioned through a first complementary set of holes at a first end of a mounting flange to movably couple the mounting flange to the mounting frame, the fastener being fastened in a manner such that the mounting flange and drive assembly have freedom to pivot about a longitudinal axis of the first complementary set of holes, and an adjustable length coupling device having a first end coupled mechanically to the mounting plate and a second end coupled mechanically to the mounting flange at a location substantially opposite the first end of the mounting flange.
