Gobi Rack - Issue with mounting brackets and loose bolts?
Hi All,
After I installed my rack, I noticed that my mounting bracket bolts were slightly loosened, so I tightened them back up and called it a day.
Yesterday, I checked on the bolts again and they still seemed loose, so I tightened them till the point where my thumb couldn't push the wrench anymore (so definitely not forcefully tightening them) and called it a day.
Well tonight I just checked on them again, and they're loose again! Not like super loose, but I had to tighten them back up again maybe a full turn?
I do have some thread sealant on the bolts, but has anyone else experienced this?
Thanks!

maybe add some locktite and lock washers to help? i think the blue is what you want to use, the red is a more permanent solution.

I second the lock washer idea, or maybe using self-locking nuts.
Has there been a huge difference in the high and low temperatures?

Which bolts? The allen bolts or the bolts that bolt to the rack and connect to the Gobi's feet? I tightened the regular feet to rack bolts really really tight. The allen bolts that bolt to the roof of the 4runner I just put some silicone on the threads and tightened them tight but made sure not to over tighten them.
I never used any locktite with my Gobi and never had an issue.

throw it in the trash!!!
i wouldn't use a split lock washer it would et water in. Get the one that looks like a cog and use some silicone to seal around it too. So, lock washer, washer and some silicone is what i would do. if its loose then water is getting in for sure.

The 4runner has been in the garage for the past few days, so the temp hasn't fluctuated too drastically.

The allen bolts that bolt the mounting brackets to the roof. I don't think I over tightened them at all, but I'll check again tonight to see if they loosened a bit.

I'm using a sealing washer with some silicone.

Just to verify what's really going on, you might want make a small mark on the allen heads with a permanent marker to see if they're really turning and backing out, or perhaps you have an issue with whatever they're threaded into, that is slowly pulling out of the roof. I don't know how much structure is under the roof to hold those bolts - my guess is less than you'd hope for.

That would suck if it was the latter!
Basically I installed the roof rack and tightened all bolts. Then I went to check on the bracket bolts again a day later only to find that they weren't tight like how I left them the previous day.
I'll check again tonight.

I've had the same problem with mine. Locktite is not a bad idea. I'm going to give that a try as well, (even though when I installed it- I'm pretty sure I already put some.....?)
As for the split washers etc. I was in disagreement with my friends during the install, i thought the order Gobi suggested was odd...

Bolts seem to be just as tight as last night, so maybe I didn't tighten them up enough from the beginning.
I'll continue to check periodically.
