exactly what are you looking to replace? i am in the process of doing mine. firm feel gets $100 for bearings and seals. there are 2 worm shaft bearings, 2 seals, and a top gasket that can be made out of gasket material, or cardboard, rtv, whatever. i couldnt find all the parts from one location other than firmfeel, but shipping was cheap enough. the seals and bearings were all 5-7$ each. i dont have any good parts stores around here but you might be able to just take the numbers to a napa or something and get them.
