I have a 2000 L and i've been hearing a squeek from the rear window or the bedmounts. Possibly the bed mount bushings? Anyone else? I only hear it at parking lot speeds and with the windows down..

 

Yep, on an 02. After I come to a full stop, as soon as I apply gentle gas I hear some squeeking sounds from the back. Haven't located the source yet, but I suspect the axle and mounts.
Changed rear brakes 2 weeks ago, and gave all the axle mounts some WD40, and it dissappered for a couple of days, but now it's back again and even louder.

 

What about the bedmount bushings? I hear the squeeks when i'm driving slow, usually on rough terrain (gravel driveway). Even louder when rear window is open!

 

Only when its in park with my girl.lol...

 

I guess i set myself up for that one!

 

i noticed my truck does this too...glad to know it wasnt just me....lol

 

My bed squeaks as well, bed sits flat on the frame (nothing in between like the cab) I've lifted each side of the bed and stuck a glob of grease at each point they contact and thought it worked for a while, came back so I tried some sheets of teflon and that didn't help much either.

 

Strange as it seems ... Check your tailgate ... The rubber
stops have a tendency to squeak like a **** ....

 

1st thing I checked. went as far as taking it off for a week and it still did it.

 

I had that, and then the latch on the driver's side started to squeek. A little WD cured that.
