I recently got a new top for my table saw because the old one was rusted beyond repair. I cleaned and reassembled the saw, and despite everything moving more smoothly, the same problem remains as on with the old tabletop -- when cranking the saw to 90 degrees, it almost gets there but then starts to bind. It's not hitting the stop, but there is some heavy resistance (and will even pull at the side of the casing as you crank). What am I missing? You can eventually crank it to the stop, but it is a two handed, potentially damaging amount of work.
