Cab Rubber Squeak From Rear Boot Cover?

[Eric (Plug Guy)]

My '99 has been a relatively silent car for a number of good years, but last summer I noticed a noise sounding like rubber on rubber from the rear boot - the cover just ahead of the engine lid.

I've used some gummi on the seal.

The problem is only evident above 60 degrees and after sitting in the sun. Almost sounds like the old days of rubber motor mounts, or dead shocks - but it's not that bad. It's slight enough to sound like light creaking when I pull out of my office or over a speed bump, but not too bad once I'm on the move. And if the temp is low, or a cloudy day, nothing.

I've checked most of the major issues, and it's odd since it started at about year five of the car's life. I've even adjusted the little pegs up under the boot cover (open it and you'll see them there) but no luck.

And yes, I know cabs are prone to this - but with five years of relatively noise free life, I know I can get it back to that.

Anyone have specific tips on where to apply the gummi or what else to look for?

Thanks!

FIXED!

I had enough of this noise. Was beginning to wonder what the hell would cause so much squealing. Last weekend after washing and drying the car, I opened the top slightly until the boot cover moved back, and I checked the seals along the back edge, which I had 'gummi'd' already.

Then I closed it up tight and cleaned the rear plastic window. As I was buffing the inside of the plastic window, down in the lower corner, driver's side, I created the SQUEAK on my own!!!!!

I reopened the boot cover, and applied gummi to the bottom edge of the seal along the back of the cab top - but NOT all the way across - it was just in that one corner (I did the other corner too).

Today, temp is above 60, sun is shining, and my cab is noise free.

I had a similar noise last summer, it seems to come from the interior back part of the car. In my case I have a 99C4 Coupe, and the cause was the rubber pieces at the rear sway-bar. After the years they have became too dry, a little grease and noise goes away.
