It is also possible that the crank arm is loose/worn causing the play but usually its the BB itself.
Ok....is there a recommended 'group' or set of BB/Crankset tools I'm going to need? Don't mind buying them, just looking for some guidance to get the 'right stuff' on the first purchase.
While pushing/pulling on the crankset....it isn't the BB that's moving (unless it's moving internally where I can't see, allowing the crankset to move). It's the shaft/crankset moving through the BB.
