They likely need to be re-lubed. Poly actually naturally grips, so it creates heat and breaks down lube over time, and as the lube breaks down or leaks out the poly will bind against the steel and cause squeaks. Something like delrin is self-lubricating against steel and will have a lower kinetic friction than steel on steel.

I concure. I always recommend installing zerk fittings and using quality Energy Suspensions poly grease.
delrin is a better alternative.

One of the worst things for this is WD-40 or the like...it might stop the squeak for a day, but it will wash out any lube that you originally put in the bushing when you installed them....then you will be left with a really squeaky clean bushing that will make more noise.

You can try some silocone spray. Silicone is what's recommended for poly. I've used it and seems to work for quite some time.

I've used that too on a friend's car.

+1. I bought a can (when I used anything but del-a-lum in the past) that had the spray "wand" or extension. Really helped shoot it in there. Originally Posted by Vegas69

Do you still believe in all the things that you stood by before? Are you out there on the front lines, or at home keeping score?

I put the poly-graphite bushings in my Camaro when I had it. I also put in new stock springs. Front end was so tight that I didn't have hardly any suspension movement. Yeah, zerk fittings would've helped, but I wasn't pulling everything apart to put them in. I got rid of the car by that time anyway.
When I rebuilt the front of my Cutlass, I used the GW Del-A-Lums and 5662 (702#) front coils. I had more suspension movement with twice the spring rate.
The only poly I'll use now are in a non-movement (body mounts, etc) application.Doug Gulley

This is why you will never find poly bushing in my front control arms. Once it starts to squeek it is going to bind pretty quick. I would loose the poly and go back to rubber (street car) or Delrin for a street/track car. I fought poly bushing while I worked at Guldstrands for years and it beat me. BTW my Chevelle has Moog rubber in the front of it and my Monte has rubber in the lowers and delrin in the upper.

On the one vehicle that has poly bushings, and works well, is regular 20-50 motor oil (new). Thick enough to stay in place, and no more squeaks.
I use it for a general lube for various 'stuff'.' Have a small lever type pump can to apply it.
For suspension bushings should place some newspaper, or if outdoors, some corrugated cardboard under the locations. As it can drip off for an hour or so after applying it. Although it depends upon the application volume.
However, the suspension won't squeak after that for quite a while.
Until I switched to the oil, they _ALWAYS_ squeaked. Didn't matter if I just greased them or not.
Once they were oiled, _done_, no more squeak.
