I'll have part II posted when I get back from MX, if all goes as planned we are taking the hundy to La Paz chasing the B1k. Names have been starting to stick, thusfar its 'Hulk' or 'Millennium Falcon'?

I believe you meant to say "Death Falcon"

How about Eagle 5

This is where I would post a picture of the flying Winnebago from spaceballs, but tapatalk has decided to not let me post pictures.

Eagle 5 has promise bit I've commited to Death Star, last thing I want to do is give the poor truck an identity crisis. :D

Cool 100 - where's the pics?

Kurt,
One questions about the front diff. Not sure about the US spec 100's but here in Oz there are two things you must address on a 100 before any serious off road:
Front lower control arm strengthening (welding) along with better torsion bars and shocks. I've posted a bit here about the lower control arm reinforcements.
Front diff "fix" (typically replace the carrier with an ARB unit) due to repeat and frequent failures.

Does the same apply for US spec 100's? :sombrero:
Cheers,
P

Yes and no, the front lower control arms can fail at the torsion bar mounts similar to the ones you have posted but I've not personally deal with a case here locally and I have quite a few customers out really bearing their 100's (Paul May from Equipt for example). That said I've already installed strengthening plates on my build (bolted on then welded) along with OME Torsion Bars and Nitro Sport Shocks so I'm feeling good about things up front :D

The front diffs were in fact an issue on 98/99 100's with the 2 pinion differential, 2000 & later had the 4 pinion diff and failure are far less common. I'll address that if/when I install and ARB but given mine has the 4 pinion diff I'm not concerned about it failing.

Thanks for chiming in, love your build! :cool:

Kurt,
While the two pinion diffs are much more prone, I think that the 4 pinion is far from immune to this. The link is to an album of me and a couple other guys at RC. The last 3 videos at the bottom are a pretty tame (but steep) hill climb. We all failed in the videos, but I made it up the second time. Simo--in the black 06 Lx, followed me and trashed his diff coming over the top--with ATRAC engaged. The grey LX lost a CV on that trip as well, and the white one had a AHC malfunction--not a good day for hundys... In any case, if you are going to wheel your hundy, especially with the extra expo weight, it might not be a bad idea to do the swap ahead of time. http://picasaweb.google.com/BROKERROB1/RCPics?authkey=Gv1sRgCIDszJ3cl9SnjAE&feat=directlink

BTW, that is me under the lx pulling his driveshaft so we could get back to the trailhead--ended up having to pull his drive flanges as well to get him back home.

Far from immune I suppose but its all perspective. They are no less immune than birfs on 40/60/80's, course spline pinions on 40's, knuckle studs on high steer 40/60's, FF shafts on e-locked 80's, and all the other 'can & do break' type deals out there and while you can 'build to prevent', this truck isn't going to see the type of uses my other Land Cruisers are set up for. Fwiw, I have several dozen 100 Series customers here locally that I deal with on a local basis, some are relatively stock but others are extremely heavy and hard used (like Rubicon, Moab, etc) and the only front diff repairs I've dealt with have all been early 2 pinion diffs. At that I can only think of 5-6 in the past few years so while its a known issue its not like every early 100 out there is falling off the road. Paul May (Equipt) has wheeled the crap out of his 8500lb early 100 for many years and only after an airborne stunt did his front diff fail :D

Its definitely something I'll continue contemplating and I appreciate your input! :cool:

Chiming in again on these, found this interesting tidbit on a Mud thread post form an Aussie source:

"To date there have been numerous reports of failures of the IFS lower wishbones, where the arm cracks adjacent to the point where the torsion bar bolts to it, sometimes to the point that the vehicle will sit on it’s bumpstop. This appears only to be evident on the turbo diesel models where the extra weight of the inline 6 cylinder and the different weight distribution of the longer engine cause the arm to be more highly stressed, particularly if the vehicle has additional accessories and has been used offroad. Some companies like ARB and Pedders are making strengthening kits to help alleviate the problem."


Either way, I'm not taking my reinforcement plates off :D

Well done on research! Your tenacity outmatches my memory. :elkgrin: I now remember that the diesels seem to be suffering from this issue based on research here on Oz forums (LCOOL.org).
