Show video on we're at the back of the truck with two metals will need to stop leak going into the trunk well

Check the Rubber sealer. The rubber that goes around the trunk it should seal it if not you would need to change it. Those parts deteriorate fast depending on the weather region.

I know, the video isn't an SC but it shows how you don't need that much room at the bottom. I have an 04 sc430 - love it but haven't had to change trunk struts yet. Good luck.

There are a couple of lexus forums that can be very helpful links beneath video...

yes they do but acess is limited by the body metal.. you can reach in but only about halfway..we had a neighbor who scrapped their blown up car a month ago.. they needed in the trunk to remove stuff before the scraphauler showed up..we removed the back seat and reached in with a long metal rod to pull all the stuff forward to tke it all out..only spot we did not acess was the spare tire hole.. could not get the cover off..

Hope this might help. I was having trouble with the trunk leaking on my chevy colbolt because of a sliver crack on the tail light, plus I also learned the colbolt have a drain hole under the trunk.

open up the trunk, and look at the metal seam that goe's all the way around the edge of the trunk area, the weather stripping, that you described should go somewhere along this area.

ls 400 - trunk leaks water. Fix -- Under the trunk seal at the bottom/rear you'll see that two pieces of metal come together. The adhesive / sealant that is used at the factory seems to leak with age. pull off the seal and use a good adhesive sealer to prevent water from leaking down between the two pieces of metal. Reinstall the trunk seal after it has dried and set properly.

buy some foam spray from a can spray it around trunk seam bottom not trunk lid. close trunk to let it dry and shape foam. also check for any holes in trunk. remove all padding to look for wholes. spray foam into any holes found. this foam can also be trimmed after it dries and hardens.

TAKE IT TO THE DEALER, THERE IS PROBABLY A TECHNICAL SERVICE BULLETIN ON IT AND THEY WILL BE ABLE TO QUICKLY AND ACURATELTY SOLVE THE PROBLEM.

Most of the time when there is a trunk leak the seal is leaking around it I would check it for any bad spots and replace it if needed.

Check for defective spot welds around the plastic inserts on the left and right sides of the trunk. If the spot welds burnt through the metal, there will be holes were water can get in. Use some JB Marine Weld to seal up any holes or cracks in the sheet metal. Also, check the rubber drain holes under those inserts, that are in the sheet metal of the car, to make sure they are not blocked with road dirt. Also, check the weather stripping on the outside of the car, adjacent to the trunk. If the rubber and chrome trim weather stripping is pulling out (on the exterior of the rear quarter panel), then water will leak through the little plastic attaching screws and into the trunk beneath the plastic containers on the left and right front sides of the trunk.
