springer Posted October 12, 2009 Report Share Posted October 12, 2009 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.

Dans07SGT Posted October 12, 2009 Report Share Posted October 12, 2009 Mine squeaks on a decent sized bump. I suspect it's the urethane bushings on the rear sway bar. Link to comment Share on other sites More sharing options...
Shelby Nick Posted October 12, 2009 Report Share Posted October 12, 2009 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. Nick Link to comment Share on other sites More sharing options...

Thanks Nick. Link to comment Share on other sites More sharing options...

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. Link to comment Share on other sites More sharing options...

And if you don't have a stereo, replace the mufflers. Link to comment Share on other sites More sharing options...

kahmann Posted October 12, 2009 Report Share Posted October 12, 2009 Thanks. 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 Ken Link to comment Share on other sites More sharing options...
08SGT1977 Posted October 12, 2009 Report Share Posted October 12, 2009 I love that sound - that is what the Shelby GT is all about! That's the FRPP suspension doing it's thing. Link to comment Share on other sites More sharing options...

Everyone says the same thing, its the racing suspension Its worse when its cold outside though Link to comment Share on other sites More sharing options...
springer Posted November 20, 2009 Author Report Share Posted November 20, 2009 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. Link to comment Share on other sites More sharing options...
Glenn Greenwell Posted November 20, 2009 Report Share Posted November 20, 2009 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.

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! Link to comment Share on other sites More sharing options...
Frank S Posted November 20, 2009 Report Share Posted November 20, 2009 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. Link to comment Share on other sites More sharing options...

If you look at any quality street suspension with poly bushings, and all race suspension they give you an NVH warning (Noise-Vibration-Harshness), sometimes they even give you a rating on how bad it's going to be..........but if you find something that works, im all over it good luck!

Glenn Greenwell Posted January 13, 2010 Report Share Posted January 13, 2010 I just got back from my first real road trip to the Dallas Cowboys/Eagles Game this past Saturday in my Shelby and my son was driving back and I was in the rear seat. This is the first time I had actually had an opportunity to hear the rear suspension squeaks etc. I have completed reading all the posts on this thread including my own comment, this is considered normal in the Shelby Handbook. My question for other 2008 SGT convertable owners, has anyone actually solved this problem or know if FORD has a TSB on this or Shelby has a suggested fix and what type of lube it is you are using? It was just a little annoying and my son and wife had told me when they were in the back seat they had squeaks and rattle issues and I blew it off. Anyone have a fix they want to share?

LGSchmidtJr Posted January 14, 2010 Report Share Posted January 14, 2010 My neighbor owns an 07 SGT and was talking recently about his suspension making more noise lately and all that came to mind was the colder weather....... I used to own a 98 Saleen S-281 and when i installed Saleen LCAs with the eurathane bushings the suspension made more noise in the colder weather....

Well I think I'll take it in and have the dealer look at it and mention this, I was wondering about trying some graphite on the bushings, I agree it shouldn't do that. Maybe SAI BUD will chime in with a suggestion also....... Glenn Link to comment Share on other sites More sharing options...
motorjock205 Posted January 14, 2010 Report Share Posted January 14, 2010 The squeak is inherent to the Poly Bushings...the Manual states that it is NORMAL...Ford or SAI is not going to do anything about it under warranty...If it really bothers you that much, do what the gentleman suggested and drill some holes in your bushings so that the grease will get to the bar in the center of the bushing. I hear mine squeak when I pull into and out of driveways and the weather is cold...no big deal, I know what it is, so I don't worry about it...I don't know why it upsets everyone so much to hear a little squeak...these cars are NOT luxury automobiles or high priced exotics!
