Not by itself, unless it's completely out of place or the pads are missing or severely worn. Normally, the tub sits on the tub support which sits on the skate plate which sits on the base assembly. The springs hold the tub and tub support to the base. The whole thing moves as a unit during operation. The tub support can move somewhat independently within the skate plate and the skate plate can move around somewhat on the top of the base. The pads allow smooth movement without metal to metal contact of these parts.
