I have a 2003 LW200 with a squeaky rear seat. It is a constant springy type of squeak while in motion. At first I thought it might be the cargo area pull shade, as that is spring loaded, but the squeak was still there after I removed it. I think it's coming from either the rear seat latching mechanism/hinges or under the rear seats. I placed a blanket over the spare tire and there is nothing in that compartment that could be making the noise.
Any suggestions on how to stop the squeak?
