Trunk Floor Lid Warped Due to Heavy Luggage - Solution

I had someone put in some very heavy luggage unbeknownst of course.

Well as you'd expect, the floor warped and it now it caves in with
anything remotely heavy.

I'm going to replace it. But would a rubber floor liner placed on top give it more support to prevent this from happening again?

Looking for feedback from those that have dealt with this. Thanks.

Rubber bends, so it will not stiffen the floor of the trunk. On my other MB, I replaced the fiber trunk floor liner. Not a big deal...less than 5 minutes to change out. I can research the part number if you need it

I would like to see what you did.

If you can look up the part number, that would be great!

I've been looking at Weather Tech. I put a hole thru the driver mat.

Thanks!

Check out 3D MAXpider(edited for spelling) for floor mats.

I’m not sure if they do a trunk mat but I can say that their floor mats are great, strong as hell and cheap. Always on sale.

There’s pictures of them in my W204 Maintenance thread in my signature.

I simply replace the cover with the same MB part. BTW...I believe that the stated load limit in the trunk is about 200 lbs. The only other think you can do to stiffen that area is to by some sheet metal and trim it to the size of the bottom floor liner, and then place it under the floor trim, so that it is not noticeable. I also have the MB plastic trunk liner, but I think the Weather Tech liner would fit better.

are you referring to 3D MAXpider? I can't seem to find what you're referring to. Website?

Yes, those are the ones.

Sorry, I was out and about when I answered this, should have looked the name up prior. I ended up ordering from partsengine.ca

Getting a rubber floor liner won't help you out here like capt_paul said. The only solution is to buy a new floor liner. There will be a sticker on the underside with the part number.

I had a similar issue as you with a sagging floor liner when I bought my car. The trunk must have leaked for the previous owner because it was splitting at one point as if it got soaked. The floor liners in these cars and most MB's in this generation are garbage. They're made out of a porous fiber that absorbs water and even when they're dry anything heavy over a period of time will cause them to warp. Many other cars in this class have rigid plastic panels for the floor liner that can hold much greater weight.

One other thing you can do is get some rigid foam blocks, or even wood, and place them in between the spare tire and floor liner. This will provide a center support.

It is ridiculous how flimsy the floor is back there. At least they could have designed it so the spare tire sits a little higher to support the floor. Could always place some 1 x boards laying across the spare to at least keep the floor more solid. I put a set of big jumper cables on the spare so the middle of the floor is at least supported. I sometimes put heavy things back there like bags of fertilizer.

if one really wanted to it wouldn't take much to cut some wood and screw a frame together so it fits under there. My previous Grand Cherokee I installed a stereo system and made a false floor to hide the amps, 1x3s, some MDF, spray glue and carpeting from Walmart. the color even matched perfectly, couldn't tell it was home made.

I forget if the underside is carpeted as well. If not just cut some 1x4 pine trim and glue it to the underside to strengthen it. Or if youre good with a jig saw cut a sheet of mdf the same profile and glue that to the underside.

The tire well is designed to hold a full size spare, which I had on my 2013. Not sure about the pre-facelift models, but on the facelift models with compact spare, the jack and tire change kit fit into a rigid plastic container that sits on top of the spare and supports the tire well cover/load floor. If that’s not there, either fabricating a support or @TimC300 ’s reinforcing should work.
