Help diagnose my vehicle noise Sign In

Hi Everyone, I'm hoping you all can help with listening to and diagnosing a noise that is coming from my 2007 Ford Escape.

Vehicle stats: 2007 Ford Escape, 3.0L V6 XLT model, mileage is 80,000 miles (130,000 km).

The noise is coming from the front end, I believe from the suspension area.
The noise can be heard when driving 40-60km/hour (25-40mph) over slight bumps in the road.
The noise is a low creaking and higher pitched hamster chirping noise that follows the bumps on road.

I attached an mp3 sound clip of the noise, any help would be awesome!

Thanks guys!

The link goes to a page for downloading an unknown file, do so at your own risk.

Have you inspected the front end components? Put on the lift and done a visual inspection? Has any repair work been done recently?





Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

Re: Help diagnose my vehicle noise Sign In

I had it up on lift and did a visual / pry bar inspection. No work done within months before the noise.

After watching various youtube video with sound, I believe the cause is one of the following: (as it sounds familiar to all of the below)
-Lower control arm bushings
-Strut rod bushing
-Engine mount

Re: Help diagnose my vehicle noise Sign In

2 cents worth on this type noise: Some vehicles (about any) control arm/strut type bushings will get a chirp/squeak from rubber to shiny metal where they do rub some normally. Rule out worn parts that should be replaced!


Solution if so: Spray with nozzle spray either a Silicone light spray. If gone for a while and returns use thicker rubber friendly grease, WD-40 is mostly rubber friendly (a fish oil) and repeat as needed. Noise if not a real wear problem will go away.


Other spots include sway bars bushings, top of strut bushings, inner fender plastic to metal fender, bumper filler parts etc.


Totally avoid spraying brake friction parts or hot exhaust parts without fail with flammable lubes of any kind. If an exhaust part/joint meant to flex not broken just fussy the silver brush in cap Anti-Seize by Permatex should work safely,

Great! I'll give the silicone spray a try and see if it helps. I have a feeling you're right about the rubber/metal being the sound.

Re: Help diagnose my vehicle noise Sign In

May not be that at all just is/was common to me mostly my own vehicles, nothing wrong but annoying squeak like you mention. Wouldn't do it in damp driving conditions just when dry so a clue there.


Beating on this. The rough or painted metal where rubber meet metal gets to wear it shiny you don't see that unless you took it apart. Sounds much like I'll describe as "squeaky clean" of washing a window or as soap is rinsing off down to fingers on glass or dare I say doing dishes!


Frequently late to know new products. Look for brand WD-40 now selling an assortment not just the one we all know of. Silicone both thin and thicker, lithium grease sprays and some others all look like the same can at a quick glance. They won't easily say "rubber friendly" but silicone is, WD-40 regular mostly is and lithium partly is. Real oils and greases can harm certain rubber parts! AYOR.


Repercussions if this is it: When silicones work and noise eventually comes back it's worse a couple times or has been for my own I would certainly know better than other people's vehicles.


Good trick if you have time: Do one spot/area at a time and test if it goes away. If nothing really mechanical you'll know where to look next time. Absolutely KNOW it's not indicating it needs repair and is just a noise only,

Re: Help diagnose my vehicle noise Sign In

Hi Tom,
Thanks for the suggestions so far.

I tried the WD-40 spray and lubricated several areas in the suspension on both sides. The noise didn't appear to change.

To describe the noise further:

It is worse on the right passenger side. The is worse when hitting bumps on the right passenger side. It appears to make the squeaking sounds going up and down. The sound is when going in straight line, over even small 1/4" bumps. The noise stays the same over bumps during turns. It is most noticeable at lower speeds (side street speeds) but I also have heard it on the highway.
The noise a few days ago was very intermittent, it would squeak for a 1-3 seconds every 20 minutes or so, when going over bumps. The sound is becoming more frequent, and squeaks for 1-10+ seconds, going over any bump on road. (is almost a continuous sound now). I will try to upload another recorded sound file of the sound now that it is continous.
When it made the near continuous noises, it had just rained out and the road was in a wet condition. So the more frequent noise may be due to the wet road conditions and the part getting wet.
From reading up online, my best guess so far is the Lower Control arm bushing is worn out. I'm going to next try applying car grease to the part as you mentioned to see if it temporarily stops the noise.

Re: Help diagnose my vehicle noise Sign In

Here is the new sound clip of the noise getting more frequent, note it is happening almost continously while driving over very minor bumps in road at side street speeds (60km/h or 35mph)

Re: Help diagnose my vehicle noise Sign In

Couldn't make your site work - no problem. You aren't harming anything doing this and could be many possible places and causes. Top of a shock or strut tower from under side has rubber that can squeak too.
Body bushings the hold/support body parts to frames, transmissions/drivetrain parts to support them both at them and some at side rail or frame parts.
Inner snap in fender shields - the bumper filler with the cheap push in zip things - all of it.


Brakes mentioned with a possible plastic backing plate even without using brakes need to know and look. If that bend it or warm it some (try hair dryer first) to push it away.


THIS STUFF DRIVES ME NUTS AND NOT A LONG DRIVE!


The key is knowing it's not a warning of an important problem.


More that are worth doing now just anyway if not the issue at all. I'll use exactly yellow Pledge Furniture Polish to rubber of doors and door jams to both protect and stop the dang sqeeks they can make too! Laugh - clean jams and repels water both w no harm to rubber or painted stuff.


Hoods have rubber adjustable bumpers to align for frond and side wedges used commonly that can use a little touch of lube or make a racket like the thing is falling apart and it's nothing.


Find it. Know it's not a warning and end it that way noises that come you know could be a real warning so not a waste of time to chase this down!


On a mission, HATE stupid noises and want to know what,


Tom
