Thanks. That's exactly where it comes from. I stop at a drive thru and you can really hear it.
I am dropping the truck off at the dealer today, I'll keep you posted on what they find.

Very Good, Mate! Interesting seems like easy fix too! Mine is High pitch squeal only after warmed up, turned off, then warmed up again....naturally I am the only one this green/blue planet that hears it too!

I am the other guy, mookdoc6, referred too and due to the cold temps have not been able to get mine to consistently squeal especially at the stealership oops I mean dealership. They did hear it the first time I visited but the technician was not available that would be working on it.. So it fell on deaf ears basically. Patiently waiting for the next opportunity or someone on this forum that finds the solution.Good luck all on the fix.

Mine was easily heard when I went to a drive thru.
The closeness of the walls made it louder. That's off course radio off window down.

Excellent post! This is good that you got your noise figured out. Temperatures are warming here so it won't be long and I will be squealing like a PIG again! Although, I am the only one who hears this unfortunately....Thanks for sharing the info!

Was your issue the squeak when the engine goes from v4 to v8? Or the tapping like sound coming from the engine bay? Glad they got you fixed up.

I too get a sporadic "tapping" coming from the driver's side of the engine upon start-up when cold, the sound goes away once warmed up, sounds like the sound thin metal makes when heating up quickly and expanding.  This is a good thread to have found for things to keep an eye out for.

Tapping sound


Did the fix in the pic work to get rid of that tapping sound? Gone?
