Im certain that model has a 3 piece crank set up. the inner crank bearing jam nut has loosened up or the bearings themselves have gone bad.first check to see if its tight, if it is then it will require a replacement set of bearing that are a pretty standard size to all bikes and can be purchased at nearly every bike shop.
