X-Cab Squeaky Door

2012 x-cab Sierra

So after googling around a bit this appears to be a common issue. I did the dielectric grease on the weatherstripping and it helped a lot but I still have a squeak. People also recommend the 3M squeak tape but IDK where to apply it really besides the door jambs.

On the drivers side x-cab door I can physically push on the door and it moves a bit. Nothing major but enough that it makes a squeak. I adjusted the drivers door a bit on the x-cab latch itself and this helped again but still as I go over bumps without a radio on I can hear it moved. I finally figured out the latch at the bottom is the issue, but there appears to be no adjustment-it just unbolts thats it.

I have on order the 3M squeak tape but IDK if its gonna work. I tried to stick a 2x4 into the door and bend the bottom a bit but didnt have much luck.

Ideas? Its getting annoying.

btw: put the 3M squeak tape on any part of the door area that contacts the body??? I would get the dealer to do it but I already ordered the tape.

My Wife helped me clean the truck and she Armor All'd the door seals. They started squeaking like mad after that.

Just use Silicone Spray on the door seals and it clears it up. Also I found with my extended cab, after about 60000K, I took it to a Friend who is a Body Man at a local shop,
He helped me adjust the doors a bit to make them seal better. He said the extended cab doors wear faster because there is no pillar, It's part of the door not the cab, as in the 4-door models. Plus the weight is all on the hinges, not the pillar like a 4-door.

Took us about a half hour. I don't know how he did it, he has a Body Man's eye. But it tightened up the doors and they don't squeak.

Good Day!
