Front-End Squeak

[dukbludvl]

I am experiencing a front-end squeak that is most noticeable when driving on rough road surfaces, over speed bumps, or even when I'm creeping along and hit the brakes hard to make the nose dive down.  It is also reproduceable if I grab onto the tow hook in front and bounce the vehicle up and down. It sounds like it's coming more from the driver's side, but I'm not positive on that.  It has been there for at least 10,000 miles. Previously, I couldn't isolate it to the front-end even as I was driving, but now I'm nearly 100% sure it's a front-end thing.  

 

Please let me know if you have experienced this "eeeerrrr-eeeeet, eeeerrrr-eeeeet" noise or if you have any suggestions as to what it might be.  Could it be the front coils?  I have an 00 Yukon 2wd with 45K miles (also, new shocks all around, but the problem continued -- or even got worse -- after the new shock install).  Thanks!

It definatly sounds like it is related to your suspension.  Have you lubed your front suspension components lately?  If not, I'd start by trying that first.
