My 2000 GS400 makes the same sound. No heat issues, coolant level is fine. Car operates normal. 80k on engine.

According to this link to Sewell Lexus (where I bought the net for my 00 LS), the cargo net for the 99 GS300 uses anchors already in the trunk rather than coming with additional anchors.

Just installed mine. I noticed ones on Flea-Bay with and without the hooks. I purchased one with hooks. You remove a flush plastic pin in the truck (both sides) and install a clip that has a bolt and finally a plastic nut with 2 hooks on it. The net just hangs from these two new hooks, nothing to do with the d rings in the trunk.
