I've got a 2005 SL500. The headliner seems loose, especially towards the rear of the car and rattles if I go over bumps.

Does anyone have any documentation as to how the headliner is connected to the roof panel and or how to remove for inspection?

Thanks in advance - David

I was replacing the headliner in my 04 this weekend. There are 9 white nylon clips (5 on the back edge and 2 on either side) that are glued to the headliner shell. The factory glue joints failed on all of them leaving only the screws on the front edge holding the panel in place. I scraped off all of the glue and reattached them with 3M Black Super Weatherstrip Adhesive. Let the glue dry overnight. The 5 clips on the rear have nylon pins that must be removed from the body and snapped into the clips on the headliner panel before trying to install the panel. For me, I was able to remove the screws and drop the panel well before the roof depressurized. The same on the installation, no more than a couple of minutes, but the cautions are to be taken seriously. YMMV

A little time baking in the Florida sunshine will tell if the glue selection was suitable, but the level of effort was pretty low.

For me this was a few bucks for the glue and very little time and patience.

I used 3m Headliner Adhesive, cut a board with some rags to apply pressure let it sit over night, lasted 2yrs and still going strong.

Now I was just dealing with the Back and passenger side back, the clips are still holding the rest up. But it saves some time and money and effort, too just shot the 3M in there, I tried another product, cant remember the name but it was garbage. The 3M is the best you can get.

my guess would be the clips coming unglued from the board, but weather strip adhesive or other flex / rubberized glues wont last long. You have to use a solid drying epoxy.
scrape, clean, sand all the surfaces and put on a metal/wood 2 stage epoxy like locktite or similar from homedepot or auto parts

I had to pull my headliner this week to replace the lock cylinder. All of the clips had detached from the headliner.... or at least were when I got the headliner off... not sure which.

It looked like they were originally attached with a hot glue type adhesive, but I'll take another look before I try re-attaching them. An epoxy type would probably be the easiest "permanent" option.

I've used gorilla glue on our SLK's door card mounts and it works great.

The clips slide horizontally into slots in the headliner, but the fingers on those slots often break or just stretch so the clips are no longer held tightly. As long as they are secured vertically, then you just need something to hold them from falling out of the slots when replacing the liner. The slips will need to move a bit, so use something pliable, like the black tar-like stuff they use for trim adhesive, or even some double-sided foam tape. You could use hot glue, but that might not let the clips "float" enough, making it hard to get them all lined up with the holes in roof frame.

Might be worth a shot. I've used gorilla glue for just about everything else! :grin

I don't expect to have the cylinder back until next week so I have a little time to play!

7$ permanent fix for clips

Mine were detached & since I had to remove it anyways for the replacement of the front hydraulic cylinder repair, I figured
it could be better than factory, which was pretty poor to be honest!

I used 2 part plastic epoxy and #3 screws 1/2" and a 1/16 drill hole. I am pretty sure that will be the end of shake rattle & roll

Don't use this stuff, I found out the hard way, when I had 1st bought the car, I didn't realize that someday I would need to get under the Headliner, thank god I only did a small area, this stuff works to good. It has been about 4yrs now, and I was bumming when I realized I had to drop headliner for repair.

Fix the headliner the right way, as I did today after replacing the Lock Cylinder.
