Squeak/cracking sound rear doors

[chris989]

Hello all,

I know this is impossible without being in the truck but I am at wits end.

Other than a little wind noise my 89 suburban has been silent. No rattle, no squeak etc. Recently i had a slapping/creaking sound,,, like a wire or stick hitting the outside of the truck.. I thought something was caught in a door.. Nothing,

The sound is coming from the rear barn door area, a creaking. I removed all of the plastic, checking inside the doors, nothing loose, Still get the creaking once in a while.... Maybe fatigued metal? does not happen over every bump, sometimes just while driving and at any speed.

I can shake the doors when open,, silent, shake the truck, silent. My last thought is I have a rock maybe above the gas tank pinching against something?? or some fatigued metal somewhere?

I am thinking of loosening the rear door strikers to take pressure off the latches/hinges and see if that solved it?

This is a long shot,,, but has anyone had a odd noise like this,, did you find the source.

Chris
