In the last year, I bought this Engine New in the Box at a very decent price. I like EF-4's as Bachmann and MTH made the engine wheel arrangement correct --- a "C" truck (6 wheels). My problem with my new Williams by Bachmann EF-4 Rectifier Engine squeaks when I back it up and shut off the power and it coast for a few inches. It has a squeaky sound. I have oiled all parts of the bushings and the center rail pickups. The problem persists only when the loco is backed up. I also, took the cab off of the loco to get to the rear Flywheel Can Motor. There is plenty of grease on the gears and a put a drop or two of oil on the wheel bushings again....and on the test track the motor makes a squeaky sound.
