Help for a squeaking front end

[ez1]

Hi,
Anybody know what's making the front end on my 69 sound like a donkey? It's most noticible when I go over a speed bump. It goes HEEE on the way up and HAWWW on the way down. If I press and rock the front from either side It just screeches away. I had the ball joints greased and silicone sprayed the sway bar ends. Still screechin' Any ideas?

Could it possibly be Poly Bushings?

The bushings are black. I think they're rubber. But I don't know . Are poly bushings black as well?

If they are black, they are most likely rubber. Squeaks can originate from different sources: Bushings, Springs, Steering linkages, or even Shocks. Sometimes it is hard to pinpoint where it is coming from. One way I have located an offending noise is to put the handle of a long screwdriver to my ear and set the metal part near suspected places. This may prove to be difficult to do because of the moving suspension. I even use a doctor's stethoscope, which may be easier with the moving suspension. I wish you luck!

Thanks Bill. Someone suggested I wrap the bushings (where they meet the sway bar) with teflon tape. Which I did with no effect. Well. I'll keep after it.

Inspect the A-arms, you may have a shot bushing there.

Good luck!

Hi All,
Thanks for all the tips and tricks. I've tried them all. I've been away or I'd have tried them sooner. I WD40'd pretty much the entire front end. I silicone sprayed it as well. I wrapped the sway bar bushings with teflon tape. :banghead:
I took her to Corvettes Unlimited. "It's the sway bar" he said. I told him what I'd done. He said they use a teflon spray. It made the squeaking somewhat quieter but it's still there. She goes back for a wheel alignment next week and they are going to take another look. I'll let you know how it works out.

Test that theory by removing the end links and going for a test drive. Teflon tape works Very well indeed.

CYa!

She's back from Corvettes Unlimited any no more squeaks.;worship Some white grease in the spring pockets and she's quiet as a mouse. I went back and forth over the speed bumps in the parking lot this morning and nary a sound They also did a wheel alignment and she rides like a new car. So now I'm going to get new tires to replace the unevenly worn ones I'm riding on now (225/70/R15s). Any suggestions? I like big tires with white letters.
