GU roof lining removal and applying sound deadener

[FNQGU]

Thought I'd throw up a few pics of the process. Very easy at the end of the day and probably took me about an hour and a half.

I decided to start at the back and work forward. The roof lining in the GU is in two pieces with the cargo area overlapping the front piece.

Start by removing the rubber cargo door seal all the way around and then remove the side trims from around the rear windows on both sides. You'll need a phillips head screw driver, a 10mm socket and 1/4in drive, and if you have them, a set of the door trim removal tools.

Remove the interior cargo bay light. Pull off the clear cover, then undo the two phillips head screws. Note, I had previously disconnected my battery as a matter of course.

You will need to undo the middle seat belts for the middle seat at the bottom and then feed it back through the plastic trim panel.

The rear part of the lining then drops down easily and can be removed from the vehicle. The interior light feeds back up through the hole in the panel and I then simply screwed it back up to stop it flapping around.

I then used a bit of acetone to give the ceiling a good clean up. The old felt padding doesn't cover the whole ceiling and if it isn't falling down, it comes off very easily as it is only held on by a bit of double sided tape.

Of note, there were no steel rods to be found anywhere in my vehicle.

The forward ceiling is a little more time consuming, but not much.

The pillar covers and grab handles all need to come off, along with the sun visors and any over head lighting or consoles.

I didn't remove the B-pillar covers, as they held the lining in place nicely until I was ready to lower it down.

I also took the opportunity to tidy up the wiring to my UHF coming up the front passengers side A-Pillar.

All the felt came off easily and I will replace it all with a few sheets of dynamat or butyl sound deadener, and then some foam overlay to help with the heat coming through the roof.

Yeah, good idea. Hopefully the sound deadener and replacement foam lining arrive today. I did just put a bit of expandable foam into the structural cavities at the front and rear to firm things up and insulate them somewhat. Will trim it up today once it is all set hard. Wicked stuff!

Being cleaned up and ready for the sound deadener and new foam insulation.

So today I finally managed to find some time to continue this little project. I picked up two meters of foam insulation from Jenkins Rubber (2.0 x 1.2m) for the ceiling spaces, and found by the end of it I had about 30cm left. 1.2m just happens to be the exact width of the ceiling spaces so it was a handy buy. The foam itself is fairly light, and came with an adhesive backing at $33/m. I also happen to have picked up a couple of meters of the Car Builders waterproof foam lining and if I was to compare it, the Car Builders product is denser and heavier for the same thickness. I'll use it on the floor.

A couple of pics...

So, I am still waiting for the dynamat to arrive, and these pieces are all just cut to size and sitting there. The ceiling area now has a much better coverage than the previous Nissan matting that was fitted but I really feel that each panel area needs a strip of dynamat to get best results. I want to fit a relatively thin strip across the ceiling in each panel area first, and then stick down the foam lining over the top. I asked the Jenkins Rubber people if the adhesive stands up to the high temps that I am sure the area will reach and was assured that it would. We'll see...

Hopefully I can get this job finished in the next couple of days. Driving around without a ceiling and without any sound proofing is quite a loud experience.

Out of interest, today I pulled my roof rack off and the ceiling was notably quieter. I then put it back on, and took it for a highway run, and could hardly hold a conversation with the radio going. My roof rack has mesh fitted to the flooring area and I reckon there is quite a decent hum coming from it when driving at speed.
