I have fitted the fitting kit for the prorack roof racks on my X-trail and what a world of pain that was ... I have although got a few questions ...
So I have those solid gutters on my xtrail and there was 4 caps to take off to be able to fit each leag of the roof rack. I took them off and screwed the load plate onto the car as expected. These do not move at all . To be able to re-add the caps back on I have to trim the inner plate of the plastic so they closed properly. This is fine too, it's expected in the instructions that a bit of trimming might be required.
I have adjusted the length of the roof racks and followed the instructions properly.
Once the roof racks are on and tight I have noticed that if using the palm of my hand I bash really hard the leg, it might move one centimeter to the left or one to the right.
On the other end, if I actually just shake the roof racks really hard nothing happens ... It's only when bashing quite hard one side or the other.
The actually load plate screwed onto the body of the car does not move at all thankfully.
Is it meant to do that ? Is it meant to be loose that way ? I cant see myself tightening the red screw even more because it's already so damn tight it hurts my thumbs just thinking about it.
Re: Hi there.
I work and sell Whispbar, Prorack, Rhino, Thule roof racks.
I must say, good on you for trying to fit them, they can be a challenge if you don't understand the roof racks.
I have a T3 Xtrail and got Rhino racks and they are in place and look fantastic.
The most common mistake on Whispbar and prorack is people not following the instructions EXACTLY.
The issue you seem to be having is not tightening back up the slide adjuster which moves the foot. along the rail. These are found when undo-ing the end caps on the feet, and the high nut which is a 6mm hex (alan) key fitting. Ensure this is tight on all 4 ppints and it will lock the bar to the foot and prevent the slide.
It has been known that curtain bars, such as whispbar HD and Pbars (square) have a clamp system which bites into the bar when tensioned on the same screw mentioned above, but if up tight and not gripping take it back and it is a warranty claim and a new one should be given.
