My original 16.0, (bought in 1980 and converted to 16.5 later on) actually wobbles more side to side than up and down. Mine has never gotten hot enough to notice, but I only clean a few albums in a session. My unit doesn't have the stainless steel tank with the drain tube, so I'm very careful with how much fluid is vaccumed up.
I took mine apart and really couldn't find anything that I could fix to decrease the wobble. I tightened up everything I could. I think the wobble is in the shaft/bearing/motor assembly and the whole assembly would need to be replaced. Mine has always worked GREAT, so I'm just going to leave it alone until it finally craps out and then I'll buy a new one.
