Squeak

[ZDPDVM]

I have an 03 2500hd extended cab LT D/A with the power bucket seats. Something is squeaking under the passenger seat when I am on rough streches of interstate. Has anyone else had a similar problem or does anyone have any good ideas on what I should check. I can't seem to find anything loose.


Thanks for your help.

Check the rear door trim at the bottom. I had a similar squeak. The door trim was popped out at the bottom, and one of the retainers was vibrating against the hole it was supposed to be seated into. They fit in pretty solid, so something must have knocked it loose.

If that's not it, try some silicone lube/spray on the latch mechanism.
