Since it's gotten cold out, I have something of a "chirping/knocking" sound coming from what it sounds like the front-driver side of the truck. And it only happens under very specific circumstances... a) when its cold out 2) driving under 45mph d)slight dips or bumps in the road (large bumps such as railroad trucks will not replicate the sound)
It doesn't matter if the wheel is turned or not..
Any ideas whatsoever would help, I'm at a loss..

 

Hard to diagnose noises on line ..... but it may be a bad IWE or cracked vacuum hose to IWE or wheel bearing maybe.

 

Indeed it is hard. Thanks for your help though!

 

If you figure it out be sure to let me know. I have the same exact problem and its driving me insane. I've looked everywhere and have yet to find anything

 

Surprisingly enough, the past couple of days I haven't heard the sound. It's almost like it's fixed itself (which I'm sure is not the case). I'm just hoping this annoying sound doesn't return.
Hope you can get it worked out
