Safety Devices Roof Rack sliding forward?

Were you driving backwards through trees or something? I've never heard of an SD rack moving like that. You have all 3 bolts in each foot, right? The vertical allen head bolts are what really cinch the rack down into the rain gutters so I'd check them first. The two horizontal bolts just clamp the foot. Find someone to hang (or stand on the roof) near each foot as you tighten the allen head bolts. Then fully tighten the two bolts facing you.

Loose bolts are the only thing that could cause it to slide like that. I once drove through so much overgrowth it ripped a Quick Fist strap. I only noticed it when the shovel was laying on the ground behind me. The rack never budged.

I ran across this pic on my HD while looking for another file and thought you'd want to see it. It's a 265/75/r16 tire next to a 255/85/r16 next to a 285/75/r16. The pic is so old they are probably original BFG KM Mud Terrains.

Brenton, you called it. Those Allen screws worked their way loose. And then snapped off when tightened. I'm replacing them with grade 10 machine screws. The stainless hardware doesn't seem to quite cut it.
Stainless comes in many grades, but in general it's not all that strong compared to a good grade 8 bolt. It also tends to gall easily, so some anti-seize isn't a bad idea for many applications. Though for this job you may want locktite instead.

I had been toying with a small wrap of rubber (bike inner-tube like what was all over the rear of that rack ;-) between the foot and gutter and wrap around the outside of the gutter to sandwich between the bracket and the bottom of the gutter (hold down function). My thinking was this would provide additional resistance at the feet and further prevent sliding. I think the OE install had some rubber material as well...
Good luck, Tom

You have those fancy limb risers and they are tied into your rack from your front bumper. I noticed the slack on them on one side and tightened it up for you. Not to much because I figured they would drag your rack forward more. But enough to keep tension on it.
So I have an idea. Relocate your mounts to the rain gutters directly. Or weld it.

Plus, anyway if you can pull the roof rack forwards just by turning a turnbuckle by hand like that, something else is wrong. Now that everything is properly torqued with new hardware, the problem should go away.
