Mick (SOAG) is right when he says the basic WD40 works better as a solvent,or rust-beater, than as a lubricant. The dry PTFE WD40, and lithium-based offerings above, are indeed 'specialist' lubricants and should be fine. I've used lithium based ones, but now prefer PTFE dry lubricant. Do check, however, that the lube. you opt for doesn't have solvent properties. Otherwise, it might well begin to eat into your ABS or Styrene bits. In any event, always shield/mask the plastic body parts off before spraying, just to be safe. That's my tip.
Shaun (Jarndice), has a massive fund of knowledge, and experience to offer, and is absolutely right when he writes that support bearings can greatly reduce output shaft (and therefore gearbox) wear.
However, success in finding and fitting them, varies from model to model. As an example, I fitted some to the drive casings of the Asiatam Panzer IV chassis. That involved reaming out the recess in the transmission casing, because the casing was a bad fit for the support bearing (Not andersherum or vice versa...). That was a total pain. Fitting them to a Tiger is quite a lot easier, and also to the Kingtiger.
I'd say that most builders/enhancers would probably recommend fitting them, though....especially if your models clock up the Kilometers on battlefields or rough terrain
