I have replaced all of my plastic seat gliders, There is still more movement than I would like, is this normal?
It depends, they have to have a certain amount. I've seen seats broken at the frame, and even the seat mount cracked too.
Is the movement in the runner or between the seat base and the back? I recently replaced my gliders 2 rear and the front "rubber gum" and that removed the movement I had. Parts supplied by B&B off ebay. Gr8 price quick delivery.
