   Two ways to fix a squeek.

   seal the parts to each other, or lubricate them.

   I would try a sealant compatible with both sides.

   Could the squeak be the tub itself? Acrylic tubs have problems with squeaks, especially if they're not set in a bed of mortar. For the few acrylic tubs I've installed, I've always spread a bed of mortar to give the acrylic tub bottom some support, and make the installation more rigid. Of course, it's too late if you didn't do that, but if you have access to the bottom of the tub from your basement, you could try to CAREFULLY drill a number of holes using a drill bit depth stop, and SPARINGLY injecting expanding foam under the tub to stiffen up the installation. If this makes any sense in addressing your problem, be sure to buy a $50 foam gun to control the foam injection and minimize the mess. Alternatively, you could cut a hole in the wall in an adjacent room to access under the tub for spray foam support or possibly even a mortar bed...

   I would try UncleMike42's suggestion first, and if that addresses the root cause of the problem, you're done!!!

   Thanks UncleMike42 and MisterEd1957. A dry lubricant reduced the squeak considerably. The tub installation guidance (MAAX) did not include a mortar bed approach; so I did not use a mortar bed. Tub has a surprisingly solid feel. Although I do have access to the volume beneath the tub from the basement (the hole in the floor for the drainage pipe is large), I am going to hold off for now installing additional stiffner material beneath the tub.

   Sounds good! The MAAX tubs look stronger than some I've seen...

   Use a hacksaw and trim the bead where it touches the tub.
