For new tuners, IMHO, there are three magic words.
Concentric - Is it round? Does it run true? Be it an Arm, a gear/shaft, an axle, or a wheel/tire. Swamper pointed out some time ago that a cockeyed pancake armature pinion can transfer it's wobble/bind down the gear train thereby affecting multiple components. Just as a whacked axle makes wheels and tires run kerflunky. The nugget there is to pay attention to how a component relates to the rest of the components. It's imperative that you proceed systematically rather than throwing a bag of new parts at something and not solving the problem or worse yet... LOL... Fixing a problem and never knowing how the heck ya got there. D'Oh! Any one or a combination of wobbles WILL hurt you bad whether the symptom is gear binding or chassis hopping.
Friction - It's a YES or NO question! Really a simple matter to isolate but care should be taken to not over relieve or excessively clearance friction points. Always take little bites! Then retest. Keep in mind that over relieving a bound friction point can create an un-concentric condition if not approached with care. Excessive friction kills cars. No exceptions!
Balance - Can apply in several different areas. Armature(both electrical and mechanical), magnet strength and comm spring pressure. Bigger magnets and gunning the comm down do not always make a better running car. Balancing pick up shoe profile and spring pressure is paramount to good handling and proper current transfer. Then of course chassis balance...if it's a three wheeler its always gonna have a quirk or two no matter how much fiddlin' you do.
