I have KYB shocks and struts. I also have polyurethane sway bar Bushings, end links and shock eyes. Right after having all this
Installed I get a considerable amount of road noise. It is very Noticeable on the highway and no existent at speeds below 30 mph, and When turning left or right it increases. It sounds like a binding Noise. The car has been checked over by several mechanics and they All are baffled. All new brakes on car as well, so I know its not
The brakes. Now to problem 2. My car squeaks extremely badly. What Can I do about it? When the polyurethane bushings were installed The energy suspension lube was applied to them. It worked for a
Little bit, but know it squeaks horribly, I can't apply more of the lube Without removing the bushings which I really do not have the time to Do. Is there a spray that works well? I tried spraying penetrating
Lithium grease on it but it didn't work. Any suggestions? Thank you For your time.

I am having the same problem with my greasable poly SFC and panhard bar. What kind of grease did you use? It says waterprof silicone based blah, blah, blah. Can you use what you normally use on your regular grease fittings around the car? How do you know how much to put in.

Thanks, Ron.

So you replaced the stock bushings and get more road noise. Yep, par for the course. The binding is not good though. Did you also rebuild your front end while you were at it? Tie rod ends, center link, idler arm (the highest wear item) LCA bushings, sway bar strut bushings and ball joints? Then finished off with new springs and a front end alignment? Now for the squeaks: Polyurethane will be more prone to squeaking than graphite impregnated polyurethane. If the components are any color besides black, they are straight polyurethane. Keeping them lubed is a must. My rear ES sway bar bushings came with a new shell or bracket that has a grease fitting. I modified the front sway bar shells to be greaseble by drilling through it in the center and installing a zerk fitting. Then I drilled through the sway bar bushing to the center at the same point. Last I made circumferential grooves in the inside of the bushing with my Dremmel and a cutoff blade. I use synthetic grease on all the fittings (I have something like 18-19 in total now). I still get creaks and pops from the chassis on occasion, but I don't have any squeaking. You have to expect there will be more road noise and harshness from these stiffer suspension components. That is also why the car will handle and corner like a true sports car now. If you want a soft ride go back to the Buna N stock bushings. But you won't have the road feel and confidence in knowing exactly what your tires and suspension are doing. Your choice. I choose to be set-up for canyon carving. Good luck, Lon.

Lon,

Just an FYI to your reply. PST are the only bushings that are graphite impregnated. There has always been a rumor that the black ES and Prothane bushings have graphite, and the other colors don't. That is false, I have spoken with both manufacturers and they state they do not use any graphite, including the black bushings.

Steve,

That's interesting. PSC promotes the black ES bushings as being graphite impregnated. I have them on the front of my car and no squeaking.Hmmmm.

This might be worth a phone call.

SteveSpohn

Brett,

You mean PST? The PST bushings are in fact graphite impregnated. They are their own bushings, they are not ES.

The black ES and Prothane bushings have no graphite in them.

Steve, I have your LCA's and Panhard rod, can I use the grease I use on the rest of my car on your parts?

Thanks, Ron.

No, you can't use a petroleum based grease on polyurethane, it breaks it down.

You have to use synthetic silicone grease, that's what the bushing manufacturer calls for.

If you can't find any (it's very hard to find) we sell it in full size grease gun canisters for $14.00 - Part #902.

Steve, I was going to use PST originally since I was sold on the graphite impregnated polyurethane. Then I was informed that they use Taiwan import components. I found out that PSC sells Energy Suspension domestically built components and that they are also graphite impregated. It is interesting that it is only a rumor, 'cuz it states that thy are graphite impregnated in PSC's catalog.

Steve, Also strange on the Silicone grease only recommendation. PSC catalog claims they are imperveous to gas, oils and other "petroleum" products. I am using synthetic grease on mine. My info is from their Spring 2000 catalog.

SteveSpohn

Lon,

PSC may have ES build bushings to their own specs.

As far as the lubrication, I'm certainly no chemist or a polyurethane expert, I'm just going by what the manufacturer has told me. I figure they know their product alot better than I do.

If you look at those little packets of white grease that come with your bushings. The really sticky, gooey, white stuff....well that's synthetic silicone grease. That's what they ship with the bushings, that's what they want used.

Also note what that tiny little packet sells for in Summit, etc. They have a good racket going. I could probably make a $100 profit off a full tube of grease if I stuck it in little packets and sold them for $9.99 each like they do!

Basically I guess what I really want to know is, what is the best spray that I can get for my bushings at a autoparts store or a Walmart. Thanks.

You can try silicone spray. I have used it to assemble my LCA's when their urethane bushings give me trouble fitting into the brackets. But I don't think it will be anything but a temporary band-aid at best. My best recommendation is to take them off again and re-lube. Go ahead and modify them with zerks while you are at it so you don't have to do this again. If you don't modify with zerks, then use the sticky silicone liberally. If water washes out the lube it will squeak. Good luck, Lon.
