Prodigy 4 link/ speedtech suspension squeak!!
 

I have the Prodigy/Airbar 4 link in my car as well as Speedtech UCA/LCA's, and Hotchkis front sway. I have the most annoying suspension squeak that I cannot find. Every grease point in the front end is done, all eurethane bushings are greased and it still persists. Is it possible a Heim Joint is making noise in the rear end? It's making the driving of the car annoying but I can't seem to find the source. Any ideas?

I cannot tell you where it is but I can tell you it is highly unlikely it is a rod end on the Prodigy Bar unless one end is loose and moving in the cradle.

It's the end links. Take some silicone spray and lube up all 6 end links and it will fix it. :unibrow:

I double checked everything when I had the car up on the weekend re-greasing all the urethane contact points. Anywhere I have urethane bushings I pulled them out and greased. Didn't make any difference.

My tailpipes were rubbing in the rear and it sounded like bushings squeaking. Might check for that.

You aren't listening, it's the rod ends on your upper and lower control arms in the rear. I'd bet on an upper at the rear end housing. Spray them and work them back and forth.

Sorry Vegas, I thought you were busting Franks balls about something personal with your comment.:unibrow: I will try the spray tomorrow. Thanks!

No problem dude...:cheers:

He bust my balls constantly like a brother.

If that fixes it on yours I would like to know. Those are Kevlar impregnated and should not squeak.

Let me know

Thanks Frank. I don't know what else it could be but the joints. With both windows down, I cant really tell where its coming from. Its only under mild movements of the suspension. They are pretty much the only moving parts. I don't think it could be the Bilsteins in the front or the QA-1's in the back. I would say I don't even have 500 miles on the whole set up yet. I have grease coming out of the sway bar and front UCA and LCA's so they are full right up too.

Just turn the radio up or get a bigger sub.

what he said ^ lol

thats the first thing i always tell customers, JK

If you can hear it by bouncing the car sittin still then if you can get underneath it or have it on a drive on lift you should be able to "feel" it with your bare hand on the joint or the arm that is making the noise. In other words, what you feel in your hand is in sync perfectly with what you hear.

I chase these noises regularly on new "regular" cars and this method really works well believe it or not.

I dont know if the stock am radio and dash speaker are gonna cut it.:D

What's the verdict? I'm right of course. :unibrow:

of course lol

Goes without saying.

Thanks guys...:unibrow:

Its been raining and crappy for the last week and a bit. Hoping to have the car out in the next couple of days to check and see if the magic silicone spray works. I loosened off all the heim joints with the suspension relaxed, compressed it back up to ride height, aligned all the joints and tightened it all up again. I also regreased the sway bar, upper and lower control arms again while the car was in the air. We will see what happens.

Got a break in the weather and took the car over to the body shop for an evaluation this morning. Squeak is still there, but not as bad. I think I will hit the joints a few more times and see if it helps.

go to a GM dealer parts dept. and buy a can of spray superlube, i can get you the part number if you need it. when it come out of the can its really thin like PB blaster but when it "drys" its greese. flows into tight spots really well.

When I used the Silicone spray I workned the uppers back and forth through their travel to distribute the lube.
