When using the largest 'ring and on the 4th or 5th (of five) rear sprockets, and pedalling at normal speed, I can see 3-4mm of side-to-side movement as each crank is at the maximum drive point. There is no play in the BB bearings and the cranks & 'rings are tight so is this typical or just my Explorer showing it's age/weakness?
