I am in the market for new shocks on my '99 suburban k1500, so for now it gets kind of noisy and rough on the back roads that I commute to work on every day. Every once in a while going through some rough stuff I will get this noise that sounds like something is loose in my drivers door. I have inspected the door panel and the window and the latch and it all seems to be intact and solid. I'm sure there is something loose on the inside of that door panel but I just want to know if anybody has had this similar issue, is it worth it to peel the door panel off and see what it is?? All my power window/lock controls are in working order and mounted correctly....It's like that one thing you have been trying to remember all day and its bugging the heck out of you....just gotta know what it is.
