remove the top access panel 3 screws in top rear.
now look around and push on the drum from top
it has suspension shocks and springs like your car they should resist any movements.
look/wiggle the concrete balance blocks , no cracks or loose.
inside the tub are the arm solid /not loose.
run it with the top open what do you see/hear and where
look under the rubber flap in front did anything get under the tub

Unless your front loader is set firmly on concrete and leveled to perfection, the force of a heavy wash load spinning in excess of 1000rpm will create a bit of vibration and noise.A firm footing is your best defense against to much movement.
Also due to the earlier movements during the spin cycle, the shocks that are used to dampen the spin cycle might have been broken or damaged.
If the problem persists inspite of proper levelling, please do check for the shocks or might have them replaced them for good.

most front loaders are balanced by a large: ready for this: cement block inside at the top of your machine and because spin is so fast it can sometimes hit inside your machine or it has brokin a peice off ,sorry but yours going to have to get the repair person out.adrian
