Yes, there are hard white plastic bushings (I think they are made of Delrin) between the outer support post and the inner piston. Take a good look at the bottom of the table to see exactly what is loose. It could be the support bushing collar is just loose, you may be able to push it back in place to tighten it up. It could also be cracked or worn where it needs to be replaced. Also check all the screws and locking hardware.
