Has anyone attached a Yakima rack with the Q-clips? If so can you post a photo?

I have seen the permanent install on the rails, but I am a little leery of drilling into my brand-spanking new MDX.

UCLAMDX has Q-tower type Yakima rack

jmh,

I believe UCLAMDX has a Yakima rack with Q-towers/Q-clips installed on his MDX. Maybe he can post some pictures.

I researched the Q-tower option prior to installing Yakima tracks and rack on my MDX. This solution did not work for me. There are limitations on where the crossbars can be positioned because of the way MDX rear doors/c-pillars curve. The Q-tower type installation results in the following deficiencies.

Functional:

1. The front cross bar is directly above the moon roof - loads may block or interfere with the moon roof, wind noise is more obvious and fairing can't be used to reduce it.
2. The rack is positioned too far forward on the roof - it is difficult to evenly distribute longer loads.
3. The maximum spread between the bars with Q-towers is 32" - some utility is lost if you need your bars to be spread farther apart.

Esthetic:

4. The 58" cross bar recommended for Q-towers on an MDX is too wide and sticks out on the sides too much - this does not look very good, in my opinion.
5. The actual Q-clips that hold the Q-towers on the MDX roof are very obvious because of the shape of the MDX roof (2"x3" black metal strips will be visible between the Q-towers and the top edges of MDX doors, unless you have a black MDX) - this, again, is not very esthetic, in my opinion.

Of course, if the deficiencies outlined above are not significant obstacles in your case, then Q-tower type Yakima roof rack may be the right solution for you. Otherwise, you may want to consider permanent installation of Yakima tracks with Railrider towers. It is not that difficult, it provides a secure and flexible solution, and it looks good.

Good luck.

Details Your Yamika Rack Install

mgmdx,

Thanks for the reply. I do have a couple of questions:
1. What length crossbar did you install? You say the 58 inch bars are too wide, did you cut them down or install the 48 inch bars?
2. I am looking to be able to put up to three bikes on the rack at a time, do you have any space limitations with the narrower bars?
3. How much weight can the Yakima Railriders with the Tracks hold? Could I add a cargo box in the future? I don't want to have the roof dent when I put some weight, but not more than 100 lbs, on the rack.

Thanks again for your help,
jmh

jmh, in reply to your questions above:

1. What length crossbar did you install? ...
I used 48" cross bars. This gives me approximately 40" of usable cross bar space between the towers. Cross bars stick out only 3" beyond each tower.

2. I am looking to be able to put up to three bikes on the rack at a time, do you have any space limitations with the narrower bars?
According to Yakima, up to 4 bikes can fit on 48" cross bars.

3. How much weight can the Yakima Railriders with the Tracks hold? ...
Although there are no fit specifications for the MDX, this type of installation on similar SUVs is rated up to 125 lbs. As long as you do not exceed the weight limit, you should easily be able to add a cargo box.

You can find additional detailed information and pictures of this setup installed in this Yakima rack discussion thread.

More Photos

Mark,

I saw the photos in the other thread along with the great details of your installation. Do you have any other photos that better show the exact placement of the tracks on the roof? I am thinking that the permanent tracks are the way I am going to go, but want to get a better feel for the location of the tracks.
Thanks again.

Thanks

One more question, do the tracks have a rubber seal that goes between the track and the rook. My factory tracks on my old 4Runner had a rubber seal, but from your photos I cannot tell if the Yakima track have this feature.

Thanks again.

jmh,

There is no rubber seal, there is a plastic "gasket" that covers the bottom of the entire track.

jmh,

As promised, picture incorporating measurements for placement of 42" Yakima tracks is attached.

Any remove factory RK or used bolted rails (not plusnuts) ?

The factory rack is pretty useless. I've removed it and put it back on just to be sure it can be done w/out a problem. Need to know from those of you with non-touring models whether there is a removable section of the plastic rain gutter trim (about 5-6" long) where the fixed posts for the factory rack would go, as if you were to add it on after purchasing the vehicle. I assume there is a removable cover piece, or else how would the dealer install the rack (especially since it is availabe as a dealer installed accessory) ? . I'm asking so that I can see how to cover up the space after I permanently remove the rack to install a Yakima rail system.

I intend to carry 4 kayaks with a total weight 200 lbs, as was my custom on my previous 99 Explorer (boy, what problems that truck had). Because I'm exceeding the load recommendations by upteen pounds, I need to use the bottom bolt-through version of the Yakima rails. I've extended the rails my Explorer with plusnut hardware, and the heavy weight of my loads kept pulling up on the track (with every upward bounce) and eventually the plusnuts became loosened and I had to install gasketed nuts on the bottom side anyhow. I would like to know if anyone has dropped the headliner and what issues I can prepare myself for. I have the service manual, so I'm not totally clueless, but real-world experience is always more insightful. I also intend to install the rails on the outer side of the rain gutter, not the inner side, to accomodate the heavier loads. Its obviously much stronger at the edge of the roof, but don't know if there are any full-length channels that run underneath that would obstruct bolt and nut placement.
If you've dropped the headliner before and can help with my questions, I'd be grateful.

Bruce

TheyCallMeBruce,

There is no removable section on the channel trim. When roof rack is installed on a non-touring MDX, the roof channel trim moulding is cut to specific dimensions to accommodate the roof rack. In order to cover up the "fixed posts" for the factory roof rack you will need to buy the complete new channel trim moulding that covers the entire length of the roof channels.

Because I'm exceeding the load recommendations by upteen pounds, I need to use the bottom bolt-through version of the Yakima rails. ...the heavy weight of my loads kept pulling up on the track (with every upward bounce) and eventually the plusnuts became loosened and I had to install gasketed nuts on the bottom side anyhow...

The bolt-on version of the Yakima tracks is rated at 150 lbs maximum. I would not recommend that you exceed this limit even with bolt-through installation since you can damage the MDX roof. Whether the plus nuts or regular nuts and bolts are used is irrelevant, since it is the strength of the track (and the roof) itself that is in question, and not necessarily the hardware that holds it down.

I also intend to install the rails on the outer side of the rain gutter, not the inner side, to accommodate the heavier loads. Its obviously much stronger at the edge of the roof, but don't know if there are any full-length channels that run underneath that would obstruct bolt and nut placement. ...

The roof section directly below the outer edge of the roof channel is supported by the "irregular-shaped" roof frame. There is no access to the roof sheetmetal at the outer edges unless you are willing to drill through the roof support frame and use 3"+ bolts to attach the Yakima tracks (standard bolts that come with the tracks are 1"). I would not recommend this type of installation since drilling through the roof support frame will definitely weaken the MDX roof structure.

Good luck in finding the solution appropriate to your needs.
