Has anyone noticed any strange noises from the rear, under-side of your SGT over road bumps? I'm hearing some major squeak-type noise that appears to be some type of rubber or urethane bushing? It is rather annoying after a while. I was wondering if this would have anything to do with the rear sway bar bushings or perhaps the shock bushings?

Any thoughts or help would be appreciated.

Mine squeaks on a decent sized bump. I suspect it's the urethane bushings on the rear sway bar.

My front and rear suspension both make noise when I go over speed bumps or driveways at an angle, only. I have greased and tightened everything I could. After reading everything I have on the Team Shelby site, it is the bushings, and I realize it is very common with our racing suspension. It bothers me too, but I just try to tune it out.

Did you try any lube like WD-40 on the rear sway bar bushings? Is the culprit making this noise the sway bar bushing or possibly the shocks?

Thanks Nick.

Don't use WD40 on any of the bushings.
Your car is equipped with the FRPP handling pack. Poly bushings make noise where rubber ones don't. It's the price you pay for better handling.
Turn the stereo up at the next bump.

My thoughts exactly.
And if you don't have a stereo, replace the mufflers.

If it bugs you too badly, you can pull the rear sway bar and probably never tell the difference in handling on the street.
Good luck

I love that sound - that is what the Shelby GT is all about! That's the FRPP suspension doing it's thing.

I've not heard it on mine, but it's probably due to my bad hearing!

my SGT has rear suspension noise too, sounds like a bushing sound over bumps, I took the mufflers off and replaced them with straight pipes (muffler delete from Pipes Performance) I only hear it on BIG bumps now. Everyone says the same thing, its the racing suspension
Its worse when its cold outside though

The responses were interesting to read. The fact remains that the rear sway bar squeaks - and shouldn't. Here is what is really funny. The rear sway bar has grease zerts at each bushing, located on the bracket that covers the bushing. If you grease the bushing at the zert, the grease only flows around the bracket and bushing and never touches the sway bar where the squeak is originating. There needs to be a small hole drilled through the bushing, where the grease zert is fitted so the grease can flow down to the sway bar where the squeak originates. I've owned two Mustangs that I installed poly-bushings on and none of them squeaked. None of my friends cars, Ford or otherwise, have sway bar squeak. This is a design flaw . They should not squeak.

Now, if you're racing at the track, and squeaks are not a concern, then there would be no issue with these noisy bushings.

As I recall in the Shelby manual, this condition is normal with a racing suspension, Jeffisheretoo can most likely chime in and verfiy that.

I have a vert and noticed it more with the top down on bumps, I don't necessarily believe this is quote normal, but that is was the book states.

Thanks tapd, I saw that before from someone.

Some squeaking, a little squeaking - yes. Loud squeaking to the point that my wife says"what's that noise?" - no. Poly bushings reduce the flex of the sway bars, they are much stiffer than rubber bushings. All done to improve handling. If they squeak, it is friction and they need lubed. I'll let you know how it comes out when I get my car back some day!

WRT WD-40, it's a water-displacer, not a lubricant. It does lubricate (so does water), but that fades quickly.

H&N's rear sway bar bushings are made of some kind of dual-material rubber-like compound that doesn't squeak. It's silicon-permeated, if I recall correctly. Been quiet for thousands of miles with no lubrication whatsoever.

I put an aftermarket rear bar on my V6 convertible. It was anodized a gold color. I wanted it dark so it didn't show up so much under the dark car. I painted it black. After about a mile of driving, it squeaked so loudly I couldn't stand it. Lubricated with silcone spray, it was quiet for another mile or two. I removed the paint from the bushing areas and it was silent from then on.

My theory was that the paint surface complained when placed in shear. I would eliminate that nice blue paint on my "competition" sway bars and see if that quieted them down. Bet it would.

I'm going to use some Harley front end grease. It doesn't wash away like the regular grease. I don't know what it's made of, but Harley is pretty proud of it judging by the price they charge for a tube.

Also, WD-40 is made mostly from fish oil. I use it for everything, from cleaning tar off the car to lubing the garage springs.

Energy Suspension makes a lube, works great. The bushings on my front bar have Zirk fittings,

Mine just starting squeking from the rear only on bumps and in /out of parking lots. Never did it before, car has 7800 miles now.
