For years when using polyeurothane suspension bushings.

 
He's committed, that's for sure. I've done that for sway bar bushings before and don't feel like it's worth the time and effort in this case. I used baby powder (it's hydrophobic) for the poly body mounts on my Elk, and now lube all poly suspension bushings with silicone dielectric grease. Not a single squeak, EVER, just put it anywhere contact is made. The packets of spark plug boot grease at the parts counter are perfect for sway bar bushings. Regular silicone grease can build up and get hard and straight grease (even marine grade) won't cure the noise for long.

If you look for this but find Synco Lube it's just the German version, same thing.

I didn't realize that UMI utilized the same stuff, that bolsters my confidence in its efficacy. I found it in the jungle for $20.

Squeaking is just a symptom of a major flaw that poly bushings have, stiction. Lube on poly bushings is just a bandaid on a fundamental flaw of their design.
