Repair Thomas Heritage Chiropractic Drop Table

How to repair a Thomas Heritage Drop Table Drop Mechanism.

When the drop table no longer pops up and stays up, you need to replace the bearings. There are 3 bearings per section of the table (thoracic section, lumbopelvic section). There are two types of bearings: 2 guide bearings and 1 stainless bearing (with bbs). They are available from Michael's Chiropractic in Davenport, Iowa. Give them a call. Or someone said they are the same as the ones you have for roller skates.

I suggest you take photos of everything you do along the way so that it's easier to put it back together.

Total time to repair both the thoracic and lumbopelvic section was 1 hour.
