Test the motor by itself in both directions to see if the noise difference is in the motor. If it is noise-comparable in both directions, the problem may be with the drive gearing or with the side-rods. My guess, without seeing it, is that there is a slight misalignment somewhere that is more prevalent when torques are present while going forward. Pay attention to any ball joints and worm gearings. Lastly, you may have to use your fingers to try to feel for bindings that are too slight to see.
