There are plenty of furniture and antique repair people on the web . Several in Mesa. Have all your info ready when you call them. Flip the table over,or climb underneath and see if they are metal guides or wood guides,90 percent of the time the rollers are bad and can easily be replaced with good quality new rollers even as a d.i.y project
Call them up, I'm sure they may know of some decent people that do repairs on Antique Cabinetry, Tables.
