kudzu, there are no jambs. The pivot base is screwed right into the top and bottom of the door opening on the problem door; thus into the wood under the drywall at the top, and into the wood floor at the bottom. I just went and checked it. The base is secure top and bottom. It's the metal pivot going into the door that is wobbling. The door starts tilting at the top, where it starts hitting the side of the door opening at the top. When the people installing the doors installed them, I guess they didn't know that a solid door needed more. I ordered the doors custom made so I could stain them to match my kitchen, and they did say they'd never seen anything like them. Last time he replaced them, my husband just went to Menard's and bought them, so I don't know if they were labeled for load capacity. Said if these failed, we were out of options. That's got to be it. Thank you so much for telling me about this! These are just too flimsy for the load of the solid wood oak door we bought. The door is tilting again. What kind of load capacity should I be looking for? Should I just weigh the door when we take it off? Can you get a variety of ones with different loads at a common home improvement store, or is this something I will need to order?

Mark, funny comment. after a lot of searching, I found what I thought was a good pick for bi-fold doors. (for my laundry closet. no room for reg. doors) Home Depot had solid oak bi-fold doors. Apparently they are out of stock. right now I've got those hollow louvered doors and they are crap. thinking I may have to have someone make something because I can't find any suitable replacements.

We had louvered doors on all of our closets and switched them out. There was only one closet that we noticed a ventilation issues and we cut a hole and installed a vent. It's painted the same color as the wall and you can't even tell it's there.

That niche does not look bad. It would be easy to fit in two slim cabinets on either side of the machines to hide the dryer vent and supplies. Unless that is in an area that guests will always see, I would not go through the hassle of doors. Maybe some art on the wall and leave it as it is. The area looks very clean and spare.
