JEEP Tube Type Rock Rail Install
I had been wanting to put a set of the "tube-type" rails on my Trailhawk so I bit the bullet and ordered a set from my local dealer. Jeep should have installed the tube type rails on the Trailhawks from the get go!
Best advice if your going to install your own.
1) Buy a metric 6mm / 1.0 thread pitch plug tap (about $8.00) and a can of WD-40. Run the tap through the "nuts" that are welded to the rail that will bolt up against the pinch weld seam under the vehicle. The nuts will be full of powder coating and some weld splatter. Don't use the bolts in the kit to clean the threads.
2) Roll the Jeep up on some 2x10 boards, just that little bit of extra clearance helps.
3) Having a buddy help lift the new rail(s) into position helps but isn't necessary.
4) On the body pinch weld seam(s), 8 holes per side, elongate the holes about 1/16" on each one of the hole. You don't want to make the hole bigger in diameter, just want to remove a little material on the sides (horizontal).
I also took the time to apply some rust-oleum paint along the edges of the holes.
4) NOTE: The instructions say to first lift the rail up and loosely bolt it to the body pinch weld seam (under the vehicle).
DON'T do this because it will be a royal pain in the arse to get the rail up and over the 12 bolts that are up along the side of the body. These are the bolts you see when you open the doors.
This is where the "buddy" comes in handy. Instead, lift the rail up and position it over the 12 bolts (by the doors) and loosely attach the flange nuts. Next use a couple of jacks to raise the rail up to the body pinch weld seam.
Now you can check for hole alignment and make sure you can start all the bolts with just your fingers.
Then put the stifferner bar up to the pinch weld seam and start inserting the 8 bolts. Having elongated these holes on the pinch weld seam just makes this process sooooo much easier.
Once all the nuts and bolts are snug, including the flag bolts that come up from the bottom of the rail (3 per side) go back and torque everything to spec.
