I bought a set of MB Crossbars used (not the basic roof rack) for my GL450 (2011).

I am having issues getting the back crossbar to attach to the roof. It appears to be barely too wide to reach across the span and clamp down on the two existing roof rails. I can get them in, but I can't get them to clamp down.

Does anyone have an instruction manual for these that they can scan and send to me? I am wondering if I am doing something wrong, although it would appear to be straight forward as far as attaching them.

Plus, does anyone have issues with the plastic bottom of the clamps breaking off. They seem very fragile -- I had one broken in the box during shipment and one break while I was placing it on the rails.

Thanks in advance for any assistance. I feel like an idiot that I can't put these on.

Thanks,
Ryan

Are you talking about the clamp breaking or just the lower cover?
I had a lower cover break in shipment but not in use.


The clamps are rugged.


They do need to go in exactly the right place to fit as the roof rails spread apart at the front.

The lower cover broke, but I'll get that fixed.

Right now, I can't seem to figure out proper placement of the cross bars since it didn't come with instructions. Not sure if I am having problems with placement or if I am doing something else wrong.

The rear bar lines up with the small gap/opening in the rails.
The front bar is just behind the sunroof.


I think there are marks on the rails to show where they go.

How are you planning on fixing the cover?

Thank you for the manual reference. Much appreciated.

The plastic tabs have broken off the cover. This is annoying. I know eventually the other plastic tabs will weaken with weathering -- luckily it is mostly cosmetic more than protective. (I suppose that there is some protection from the elements but it is minimal since the top cover protects most of the bar from the sun and rain.

Other than contacting Thule, I have no other recourse.

I think they are only broken from mishandling.
I have my original set and both covers are fine, and the set I bought used had one broken cover from bad shipping.


P.S. I have already tried Thule. No go!

I also have the chrome crossbars, what I did was super glued the lower covers onto the crossbars as one of the lower covers flew off in the freeway and was lost forever, I need one chrome lowercover please if someone can sell to me would be most appreciated.
