Has anyone had any experience with automotive joints being injected with a polymer filler to recondition them? With the cost of new joints plus the limited mileage most of our cars do, is this a viable option or just snake oil and marketing?
Below are a couple of links to sites and you'll get the general idea of how it works. It appears to be used by the trucking industry so you would assume the product is durable.They also seem to do various types of joints. One Facebook page for the Ball Joint Doctor even shows a set of Fairlady ball joints that he had already reconditioned for a client.

I recall this was discussed many moons ago... try searching past threads. I think in the long run we all decided to go with rareparts, or some other set up that involved or was pioneered by our recently passed member Linda but I can't be sure. I do recall having a set and replacing my (lower?) ball joints like 15 years ago...

I also recall this being done on a car on the show Wheeler Dealer. I don't think anyone was against this, but new ones were made reasonable so that's the route people went with.

Hummm, wondering if the process burns out all the old crusty grease?

Is it safe for human use ?
Lithium / white grease dries out and cakes around the ball / socket and tightens it up. The lithium is slippers also we at my dealer ( mid 70s )had a tube of grease that was used on loose joints it was so thick , I smash my hands many times slipping applying hard force to make it work , the grease gad like stringers in it

We’ve all got a few joints that need reconditioning.
