Recently my truck has really began to loosen up and the rear king cab doors now rattle over every bump in the road... Its very annoying. So I searched on here and found quite a few threads on the matter with basically only one DIY solution and the rest being "dealer magic" where it came from the dealer fixed. Well after looking at how the door latches and where the noise was coming from I managed to get rid of my rattles ENTIRELY! My truck's cab is now silent (although now I can hear suspension squeaks...) Anyways, here is what I did to fix it.
First you should start with the DIY already known on here:
This consists of "adjusting" the U latches on both doors.
1) Open both doors and locate U latch for king cab door (in the door seal on the bottom)
2) Loosen up the two torque bolts slightly and gently beat the mount in towards the truck with a rubber mallet.
3) Tighten down bolts and close king cab door
4) Repeat process for front door U latch (mounted on king cab door about halfway up door seal)
This helped a little with my rattles but I was not satisfied just yet.
Now for the fun part (This is what I added in addition to known "fix"above)
0) Here is what you need to do the real fix:
- 1" x 1/8" x ~20" Aluminium flat stock ($5 at Home Depot)
-Hack Saw
-Drill with small pilot bit and step bit, lube
-Sharpie
Optional:
-Vice
-Hammer and punch
-File
-Scotch Brite pad
1) Open both doors, locate this cover and remove it. I found grabbing the top more towards the front to be best. There are two snaps and then you have to slide it towards the rear of the truck to get it off.
With the cover off, this is what you see:
2) Take a Sharpie and trace around the latch bracket as best you can to use as a reference
3) Unbolt the three 12mm bolts and remove bracket and shims. *Note you might be able to buy these shims from the dealer, not sure..
4) Take the latch bracket over to the bench and place it over your flat stock. Mark length needed and holes.
5) Cut to length, center punch holes, and pilot drill them.
6) Secure your shim and drill the three holes using the step bit. The two outer holes are 3/8" and the inner one is 1/2"
7*) Optional* Clean up your part by filing the cut edges smooth, de-burring the holes, and polishing the faces.
8 ) Now take your newly made shims and check the holes against the bracket and mount them up in the truck. Start by only lightly snugging up the center bolt and close the KC door.
9) With the door still closed add the other bolts and lightly snug them up as well. Open and close the door a few times two get everything to settle where they are happy. After that tighten everything down real good.
10) Snap the cover back in place and bingo! No more rattles
Before all this I could grab the rear door and more it back and forth a good amount where as now I can't move it at all.
Note: If after doing this and instead of rattles you now hear like a squeaky rubbery noise, wipe all of your doors seals down with Silicone lube. This will condition them and quiet them down.
Also I realize now that I could have only made 1 shim per side by making them out of 1/4". The factory shims measured ~1/16" and ~ 3/32" for a shim thickness per side of 5/32" vs the 1/4" of shim in there now.
