Greasing polyurethane bushings

[Orangepeel]

On my 2021 wrx I have polyurethane front sway bar bushings. Every few months they squeak and creak and I go in re lube them up and they’re quiet for a bit only to get noisy again a few months later. Is there a good product I can use that will last longer to lube these bushings?

Yes, ditch them and put OE bushings.
Poly bushings on the sway bar won't work properly unless everything is poly bushings elsewhere, which will limit flex. Even then, it is questionable.
What is your goal with poly bushings? I have them in rear subframe on BMW to reduce understeer a bit on track bcs. AWD. But that is about it.

The JBR rear anti-roll bar on my Mazdaspeed 3 used polyurethane bushings. I used JBR mounts with zerk fittings and greased them at every oil change with Super Lube.

Energy Suspension makes a silicone grease that's really sticky and resistant to wash-out.

I have poly swaybar bushings on my Mustang and I've tried a number of products including the energy suspension grease and superlube grease. Nothing lasts more than a couple weeks (or less if there is a lot of rain). Ended up finding a tube a NLGI #3 silicone compound by JetLube and that has worked great. Perfectly. Last greased them like 5-10 years ago! Granted it doesn't get much ddrivetime anymore either.

The superpro, energy suspension, and superlube stuff eventually wore out on mine.

I'm trying this next, which seems highly regarded in the lotus community:

AquaShield is the answer. Our Volvo has IPD sway bars with that grease and the bushings have been silent for over 10 years, even in the rainy PNW

Silicon faucet grease/gel ... and maybe some dry moly.
Ya think there would be stuff on the market from the suspension gurus.

I’ve successfully used (Dow Corning, molykote) DC111 thick silicone grease on poly suspension bushings. It is in the same family as DC4 o-ring lube. Holds up about as long as anything I’ve tried. Does not deteriorate the bushings

Teflon-impregnated bushings. My H&R bars have been quiet since new...5 years...
