The car holder for my GPS navigation system uses a ball-and-socket joint.

holds the unit without any slipping -- but no matter how much I fuss with
it, I can never get it into exactly the position I want. There's simply

much friction, both static and moving.

I've tried silicone spray lube, but it doesn't do much good. I've thought

lithium grease, but... Nah.

Any suggestions?

Thanks in advance.

I would try locksmith's dry lubricant - ground graphite or talcum powder ,
at least no solvents going to attack the plastic

The old slide rule trick is to loosen with graphite and tighten with
chalk dust.
