This is one reason I really dislike lazy susans....especially the ones that revolve on a center pole. These have been the thorn in the side of KD's worldwide for many years. The hardware changes over the years and it's not an easy task to replace for the average homeowner. I tried to help one of my best friends replace hers. I was doing her a favor, ended up buy two replacements that wouldn't work for her 20 year old cabinets and I was out the $. My business partner eventually was able to fix it. I know she was frustrated but not even a thank you from her, she just complained that the kitchen business needs to have more service in fixing things when they break. Even though there might be some truth in that....what you need is a good carpenter or someone good with tools and a lot of patience.

First off, try to find out who the maker of your cabinets are. If you can find out....call them or dealer who has them to get help.

Here are a few online guides on how to replace. It also depends to: Is it a regular pole type lazy susan? A super susan? What is the diameter of the trays? Do your trays spin on a shelf? Or Are the trays secured to the revolving door? Or do the trays spin without the door? While I've never fixed one (I am NOT qualified to do that!), here are a few online instructions I found:

Good luck.

Ps. Do you know where your cabinets came from? If you do, see if they will help you. With parts and labor, a fix could cost $130 to $400 depending on the parts and time involved. If you don't know, then contact a local kitchen dealership to see if they will help you. Some will, some won't. If they won't, then a cabinet installer is your next best bet. Maybe Lowes could give you a list. Don't be surprised if people want to blow you off. There's no money to be made in this and a huge PITA factor. Unless you do all the legwork and finding out what will work best with your cabinets.
