Polygraphite Pst Bushings

Hello.
I recently purchased a suspension upgrade kit from PST for my tired Camaro. I have to admit that I am a bit concerned now by the split reveiws I have read concerning noise ( Squeaks ).
I am very interested in hearing from those who have had positive results with the POLYGRAPHITE components and process used to install. I am going to give these bushings a try and want to use an installation process that results in a positive outcome.
I have read it relies on proper lubing of components.

I also wonder what is an acceptable lubricant for these bushings.
Has anyone used Marine Lube ?
Thanks for reading and comments.

Ray

Re: Polygraphite Pst Bushings

I just installed prothane poly's in the rear suspensions in my car. As for the lube, I couldn't find a comparable grease to the stuff they sent. I know others have said to just use a silicon based grease, but the stuff from them was extremely "sticky", so I purchased extra grease packets from Prothane.

Re: Polygraphite Pst Bushings

I guess it depends on which bushings are poly. I just rebuilt my front and back and based on recommendations, used all poly except the upper & lower control arm bushings which are still rubber. No complaints about squeaking or handling.

Summit carries this lube. It is called Super Grease (PTP-19-1751). I bought some so I could use plenty when I installed the prothane poly bushings front and rear.

Re: Polygraphite Pst Bushings

I've had PST polygraphites on my control arms since '99. I haven't had problems with squeeking, but I don't really have than many miles on them (under 10,000miles). I have noticed that the upper bushings look like they have flowed a bit. Since joining this forum, I've read quite a few people say to go either rubber or Delrin because poly binds too much.

Re: Polygraphite Pst Bushings

Ive put the Polygraphite in probably a handful of cars, not a squeak out of any of them.

Re: Polygraphite Pst Bushings

Isn't this why they add graphite to the poly so it stops squeaks??

Re: Polygraphite Pst Bushings

I put the PST (polygraphite) full front end rebuild kit and the body mounts on over a year ago and put close to 1000 miles on the car with no squeaks. No problems, I used the grease they sent. I haven't regreased the fittings yet. The car is street use only.

Re: Polygraphite Pst Bushings

I've got these type bushings just about everywhere on the car and no squeaks. It is good idea to get some more lube cause they don't give you enough w/the kit.

Re: Polygraphite Pst Bushings

I guess I'm getting confused after reading all this.

Polyurethane components (energy suspension co.) need to be greased up. (?)
Polygraphite components (PST co.) have graphite impregnated in them so they dont need to be greased. (?)

Re: Polygraphite Pst Bushings

They both need to be greased, very liberally. But Polygraphite is less likely to ever squeak.
I put those PST Polygraphite ones in my 77 Camaro.... 6 years without a squeak... sold the car last year.

Re: Polygraphite Pst Bushings

I finished my front suspension project recently.
Used Energy Suspensions black/polygraphite bushings. Also bought an extra little thing of their lube.
Used the lube liberally on installation, followed the directions exactly.

Not a sound.

Not really harsher at all, just seemed to make it feel more "solid and pointed to where you steered it", but then, replacing the old worn out bushings with new ones, I'm sure any type of new bushing will make it feel better.

Hard to describe......

Re: Polygraphite Pst Bushings

I figure THE BEST will be STEEL on STEEL bushings/kingpins and zerks w/ moly gun-grease every oil change!

The old cars used to be made this way, BUT people were too stupid to grease them!
