So, now I have extras just in case.

I was initially concerned when attaching the towers to the flush rails. The feet don't rest on the roof. Both the claw and the foot were set on the black trim beneath the silver rail. It won't look like its attached securely when you tighten the claw. As you tighten the claw, the foot of the tower will ride up the rail.

It's actually on pretty solid. I was rocking the whole Jeep with some good pushes and tugs on the crossbar. Will keep checking throughout the season if anything comes loose.

Pictures of the setup are attached.
Very nice!!!!

OK received the pin adapter part #8880201 which consists of 2 separate parts - 1) a shorter base (the metal part that extends vertically from the RailGrab tower) and 2) a pin adapter that is designed to replace the claw for certain types of special rails (may or may not be Jeep GC - see next paragraph)

In the case of our Jeep GC I think we only need to use the shorter base (#1) not the pin adapter part (#2) The pin adapter appears to be for rails that have a small hole in the rail that the pin fits into. Jeep GC has a normal notched rail so the regular small claw makes more surface contact with underside of rail than the pin adapter so I used the shorter base (#1) with the small claw that came with the standard RailGrab kit. Pin adpater made more surface contact with side of rail but it worried me that only small pin was keeping it attached to rail.

Did find this video is showing to use the pin adapter with jeep GC rails so not sure I'm right http://www.etrailer.com/Accessories-.../Y8880201.html
I'll send email to Yakima support to see what they think.

Tower and bars sit low and gives a nice low profile look on the JGC roof. Attached are a few pics. The large round part on the my front passenger side is for a boat loader attachment that extends out which is an add on to regular bars.

As far as I can tell the RailGrab setup is pretty easy on and off. There are 2 Allen screws per tower that hold everything in place. One that holds the claw onto rail and second screw that grabs the round bar. Loosen the claw screw all the way and loosen the bar screw just a turn or 2 and the whole tower gets loose and once both ends are loose you can lift whole bar and towers right off roof. The Allen wrench even stores inside the RailGrab tower which is convenient but I will get a couple extras just in case I lose it.

Looks like I was on track. Yakima support sent me a link to a dealer fit site that has bunch of pictures and notes. fitlookup.yakima.com

This picture shows the small claw being used attached to short base from the pin adapter kit. http://fitlookup.yakima.com/GetPhoto.aspx?id=9932



Note 136 specifically mentions just the base from pin adapter kit:
136. Short Claw Base from (PN 8880201) required for this application.

Re: Yakima Railgrab Tower and Crossbar

How is the wind noise with these? I have 66" bars leftover from my 1990 F-150 setup. I would just be purchasing the grabrail kit, and I guess calling Yakima for the adapter kit.

I get a little hum @ highway speeds 65+. I hear it more with windows shut, with windows or roof open it gets lost in road noise. I'm gonna take my bars off when not in use. I bought a small aero wing thing for $25 that supposedly helps, will see.

JCG uses 48" bars so 66 would stick out pretty far on sides.

Re: Yakima Railgrab Tower and Crossbar

Did the aero wing(wind jammer) help with the road noise?

Helped a little haven't heard the harmonic type hum noise. I'm moving toward removing my racks when not planning a paddling trip.

Re: Yakima Railgrab Tower and Crossbar

Decided on the windjammer! After researching, I went with 2 jammers placed "off center" on the front bar. HUGE deference, basically eliminated all noise from the bars! Im back to a quiet cockpit now!

Re: Yakima Railgrab Tower and Crossbar

I just installed the same kit last night. I had spent hours watching videos and reading information about installing the towers, so I felt pretty confident I would get the set up right. I was taking my time to make sure I would get this right, and when I finished installing them for the first time, it looked kind of weird to me. I had seen the pics on this link (Yakima Dealer InfoLookup) (just select grand cherokee and railgrab) and mine did not look like that.
I followed all the instructions so I was thinking I had set it up correctly. Came back to the computer and spent a couple of hours looking for some sites that would provide any guidance. Finally found that you have to use the pin adapter base (without the pin) and the small claw. I thought this was kind of weird bc it wasn't specified anywhere else. I guess in the link above you will see that they do recommend using the pin adapter in the fit information, and then on the Notes below they'll say they recommend using the small claw, but it wasn't very clear.
Anyway, replacing the adapter base was very easy and when I went back to re-install the rack, the towers were still sitting weirdly. The short claw was sitting on the last two notches, so that didn't seem very strong to me. I guess I have to say that I went the lazy way and just unmounted the towers from my WK2 but left the bars on the towers.
Later on, I realized that since I had left the crossbars in the towers, that was causing the small claw to not grab correctly like the pics from Yakima show. I loosened the screw that holds the crossbars in place and repositioned the towers, and finally I was able to sit the small claw like it is supposed to be. Plus now the towers are not sitting too high on the railing.
I am using a 38" fairing like the site recommends, and it helps with noise, although I have not been on a highway yet. I can update later on to let you know how that goes.

Re: Yakima Railgrab Tower and Crossbar

Sorry it took so long to reply. Here are some pictures. As you can see on the picture from the side, it is not sitting on a weird position, but it sits firmly on the rail. I'm still trying to figure out how I feel about the fairing, because when I put the bike rack (Yakima Forklift) it was kind of a pain to install it. But it definitely does remove most of the noise created by the rack.

I installed the windjammer and that helped a lot with reducing wind noise.
