Wadia 8 transport CD drawer will not open or close on its own

I have had my Wadia 8 transport for almost 2 decades and it has functioned without fault for that time without any malfunctions, we have just sold, bought and moved into a new home in which I hand carried this piece myself, after install the transport will not open or close on its own but you can hit open, manually pull the drawer out, hit close and push it shut. You can here the mechanism trying to work to open and close  but needs physical help to accomplish the task. WTS, it looks to sport a Teac VRDS transport does anyone know of a source for this piece so I can replace it my self? By the way the unit still sounds excellent but I do not believe it would be worth sending it off for a costly repair and will probably just replace it. Would appreciate someone pointing me in the right direction. Enjoy the music
