The hammer method works because more than likely your brushes are worn irregular and that allows them to make more contact with the commutator. This was the case with mine, I could tell that going all the way one direction would kink the brush not allowing it to go the other way without tapping it. If you're mechanically inclined do what I did and find a maxima/I30/pathy/qx4 and maybe others in the same year range from a junkyard/pick a part and change the motor out. I got one from a 2002 maxima that fit my 2001 qx4. The motor plug was different though. On a maxima/I30 they have a two wire plug, the qx4 has a 5 wire plug. The extra 3 wires for the qx4 went to a little circuit board that fit in the top of the plastic motor housing. The maxima had the same motor housing with the notches for the circuit board. I switched brushes and the plugs and im back in business for 20 bucks and an hr or so of work.
Or you can go to a pick a part and find the motor grab some brushes and put them in your pocket. The damn things are tiny though.
