Rhino-Rack Install Write Up

I have the Pioneer 49 by 76 version and getting a ton of wind noise at about 50 mph. Has anyone used the flaring with the sunroof? It looks like it may be an issue as the 76 inch lands right in the middle of the sunroof.
 
Possible Fix

I have the Pioneer 49 by 76 version and getting a ton of wind noise at about 50 mph. Has anyone used the flaring with the sunroof? It looks like it may be an issue as the 76 inch lands right in the middle of the sunroof.

I was told a way to reduce the noise is to apply Gorilla Tape across the underside of the crossbars. I don’t know if this works or not but it is on my list of things to do.
 
RLT v Backbone

Thanks for all the helpful info. Apologies if I missed it somewhere in here, but I can't figure out if there's any functional difference between the RLT mounts and the Backbone. Is there a max load difference? It it purely aesthetic? Does anyone have insight?

Thanks.
 
for those running the rhino rack backbone rails. how do the rails do "naked" any issues taking the platform off when not in use and just leaving the rails up there with no cross rails or anything else?

also how is the overall wind noise with the pioneer platform 76"

I have the 83” version sitting in my basement, really glad I read your post. I just had a very simular issue with aero Yakima bars. They have a t-slot channel on the bottom as well. I used with without installing their rubber filler and they were really loud. Installed their rubber filler, no issues now. So this tip of using tape makes total sense. Thanks
 
Thanks for this. It is exactly what I’ve been looking for. My Rhino Rack 3/4 Backbone and Pioneer Rack arrived yesterday. Can’t wait to install. These posts have been very helpful in helping visualize the process.
 
Finally got it installed. Pic is too big to upload. I will have to do it from my pc tomorrow. Installed per directions and the rear door does not open. Turned the platform around and the rear door opens perfectly. 4 points of contact. I will have to drill the platform to take advantage of the middle mount.
 
Here are the pics. You can't tell the clearance when the rear door is open, but it's about a half inch.

OP did you follow the drilling guidelines that were in the backbone instructions?

I'm a little perplexed because I drilled the holes and when I put the rack up top,I found that the portion that was drilled doesn't even come close to the mounting tabs on the backbone.

Yeah there is no way it will work, I have the 83” and it just barely cleared the sunroof. It is recessed and hits the underside of the rack preventing it from being moved forward to allow the air to go up and over the rack. The fairing made the noise worse for me. Working on using the parts to design a fairing on top vs. on bottom to see if that helps, plus wind deflection over my RTT. I prototyped a fairing going from the roof up and over the rack by 7 inches using the Rhino parts. The size of the fairing was ridicules

Really a poor design by Rhino for this application

The easiest way to do it is dry fit the rack on the backbone system exactly where you want it to sit. Mark on the rack where you need to drill the holes.

"The rack has 3 cross bars that must be bolted to the underside of the rack. Placement of these crossbars is determined where you want the rack to sit on the Backbone system. This is where you will have to drill the rack in order to align the crossbars in the correct location. If you mount the rack too far forward on the Backbone rails you will hit the XM “shark fin” antenna, if you mount the rack too far toward the rear of the vehicle you may have an issue opening the hatch if you have a ladder installed."

I did that yesterday. I took it per the manual 125 mm from the rear.

I got confused and forgot to bolt the crossbars so I had to take the platform off and bolt it up

I bought the fairing as well and took it off after 2 weeks as it would make flapping noises. i adjusted several times and could not get to sit right or help with wind noise. Sucks as its non-returnable. Rhino owes me!

I adjusted the fairing today and moved it back a bit as it was making this horrid squeaking noise with the rubber pad on the roof. Hopefully it'll fix it

is it just me or am i doing something wrong.

The last "twist" nut is being stubborn with me and will not go fully perpendicular to the crossbar to securely lock in place.

Is there a technique for this? do you manually rotate the "twist" nut or will it rotate into it's place as you're tightening it? I've been manually rotating it on the other mounting points.

The twist “nuts” turn 90* into the underside channel of the crossbar and tighten down to secure the rack. There will be 6 points that this will be done at.
*Note – this twist “nut” turns into the channel of the crossbars that you had to mount and/or drill to the underside of the rack.

i'm sure you've tried it, but make sure the twist nut is in the correct orientation. also, if i recall, i believe I twisted it manually and then held in place with my finger as I tightened the bolt.
