hi all,can I engage rear drive on my sisley with the rear shafts and wheel bearings removed,reason being I am trying to locate a grinding sound,(bearings /diff) and I am having trouble in regards to its exact location.Not sure if its ok to do this as unsure how diff internals will react with the shafts out,ie internal gears,bearings etc,oh and yes, its well shored up so no chance of any runaway panda scene as have been there done that!Any help is most appreciated.
