I promised a few guys in the audio section I would post a DIY for the removal of the headliner.... so here goes. I checked the DIY sticky and didnt see a headliner thread..... so my apologies if someone has already posted this.
I'm taking my headliner down to apply sound deadener and insulation to the roof. I decided I wasnt in the mood to remove the seats and center console again, so I just tipped my front seats back and left the headliner in the vehicle. It made for a challenging install, but all the work was well worth it.
The removal of the headliner is actually quite easy.... its just time consuming. I start at the A-pillars and work my way back.
To remove the A-pillar you'll need to reveal the 2 hidden 10mm screws hiding behind the plastic covers. I used a very small flat head screw driver and covered the head with electrical tape to prevent scratching and over prying.
Once they are out the A-pillar simply lifts out.
Working my way back to the B-pillar, you'll again need to reveal 2 hidden 10mm screws hiding behind the plastic tabs on the handle.
Down by the seat tracks you'll see the seat belt bolt, its a 14mm bolt that is hidden by the little plastic cover that easily pops right off.
The rest of the lower B-pillar is only held in by the little white clips, just carefully pry it off. Once you remove the lower B-pillar cover, you'll see another hidden 10mm screw.
Once you remove the screw the upper B-pillar cover easily pops out, only being held in by one small clip close to the screw, and a tab at the top.
Moving back to the C-pillar, I only remove the top screw as the entire cover doesnt need to be completely removed, only loosened enough to allow the liner to slide out.
Another hidden 10mm screw hides behind this little air bag warning.
As you can see, just removing the screw gives me enough room to drop the liner on the rear.
Next comes the overhead passenger handle, the hanger hooks in the rear, and that little cover by the drivers head that everyone wonders what it is. All of them are only little metal clips used to hold the liner in place on the outer edges. With a small flat head screw driver (covered in tape to prevent damage to the plastic) I pried the covers off of the tabs to expose the clips.
I found it easiest to just pop out the metal clips as well. Removing the metal clips makes it super easy to snap them back in on reassembly.
Next are the sun visors, they are held in by 3 torx screws on the main assembly and one loner holding up the sun visor clip. Remove the round plastic cover to reveal the 3 torx screws.
Once unscrewed, the visors will need to be disconnected from the wiring harness if you have vanity lights.
Next is the overhead console. There are 6 torx screws holding the console up. The 2 in the rear are hidden underneath the rear light assembly. The dome cover pops off easily with the flat head screw driver. Remove the metal plate and you'll see the 2 screws in the corners.
Next there are 2 more screws hiding in the business card compartment.
Last there are 2 screws tucked away behind the back up camera housing, the housing easily pops out with a firm tug.
Unplug the 2 (or 1) wiring harnesses.
The rest of the liner is now being held up by the door trim moulding and 4 small white clips in the rear.
I started out by popping out the rear white clips, then carefully (with help from the wife) we slowly released the headliner from the door moulding and lowered it gently onto the seats. Now you have access to the roof
Again, I prefer doing this with the seats and center console out of the truck, but it works pretty good if you decide to leave them in, like I did today. Just tilt the seats back and away you go.
For reassembly... just read this in reverse.
Hope that helps,
