3 Link, Currie Rear Axle, Rear Coilovers and Long Travel IFS FJC Build (and more)

[FJNewb]

Supercharger is back on. Not sure if I mentioned it, but after running it the first time it seemed a bit louder than it should have been. Compared to some other folks and was just a bit noiser in the lobes. I dissassembled, but couldn't find any clear issues of interference or scoring on the housing. Sent it to PSE and they fixtured, tested, and measured everything...turned out the lobes were out of spec which was causing a slight contact on a set of lobes. Fixed up and should be good to go now.

The floor and seat mount were knocked out today (sorry for the iphone phots..camera battery was dead).

Last swaybar parts showed up, so that can be finished next week.

Outstanding...

obscene in the best way...

Very Nice, did you see the pic of Nicks rig flexed out at Roundup? You gonna turn that into a trailer rig or keep it a driver?

Yes, saw Nicks photos from the roundup, looked like it worked well. Definitely like the paint scheme he did.

We started off with the same rear setup, at the begining of this project, and ended up selling it. Still did a 3 link, but altered the geometry towards the characteristics that we were looking for and ran coilovers to yield more travel and articulation than MT's "kit".

It will remain a daily driver for at least the next couple years. May get a tow rig down the line (more for towing other potential project) and use it to trailer the FJC to some events. Mainly just so I don't have to deal with the hassel of breaking some of the more unique which you cant run to Toyota or the local autoparts store and pick up.

Any pictures of it in the dirt??

Read the thread, its a build in progress although its seen plenty of dirt time before the currrent "renovations"...

It's a garage queen. I don't think it's ever been in 4wd.

Hahaha.

 

[BAMF FJ]

Got it.. Nice build.. 11 months, holy crap I'd be goin through withdrawls from dirt like crazy.... Can't wait to see her done

Remote fill is in. Located so that none of the quarter panel structural supports had to be chopped out. At this location its just sheetmetal to the exterior.

Will toss on the switch and work on the center section (what runs between the driver and passenger seat) tomorrow. Good visibility tho as you can still see all three screen from the drivers seat and the GPS is in reach of the driver if riding solo.

Guages just about wrapped up. Only one more to find a spot for.

 

[FJNewb]

I'm sure the knowledgable folks on here with have some insight to share...blueroom was crickets with the questions below.


"Getting lazy and tired of sifting through the FSM. Anyone know if the FJC has an inertia switch from the factory that kills fuel flow to the engine?

After getting rear ended in the mustang a few weeks back I had forgotten it had one and why the engine would turn over. Figured the FJC might have something similar.

So far found the resistances for the seat belts, still looking for the air bag squib resistances (driver side), and if it has an inertia switch.

Any insight from the Toyota Tech's out there? Also, I didn't see specific information on the airbag setup, but is there any basic information on what "typical" g-forces the accelerometers set them off at?

 

[Delancy]

Ford is the only I know off. My Expedition had one that failed, and wasn't covered under warranty (5,500 miles). I recall the tech explaining that Ford was the only he knew of that utilized, and all other manufacturers cut power to the vehicle with air bag deployment.

Not sure if this helps, or not.

 

[Mtbcoach]

My only contribution is knowing someone who totalled (heavy side impact w/rollover) theirs and it still ran after.

I don't believe Toyota makes public the forces necessary for airbag deployment. I recall plenty of discussion in the "early days" of the FJC but have no hard data to provide, sorry...

 

[BMThiker]

I don't know any details about the above mentioned systems, but I thought there was a pitch/yaw sensor mounted on the tranny hump just aft of the shift levers. As I recall it was a square box maybe 2" x 2" and only about 1/2" thick. Maybe you could trace the wires to something pertinent.

 

[FJNewb]

Thanks for the comments/feedback. I'll have to dig around more to see what I can find out in the service manual and what wires go to what underneath.

I haven't heard of anyones airbags (or fuel kill switcH) going off yet in baja style runs due to the gforces, but just something I wanted to be cognizant of if anyone had info. Thanks for the help!

 

[sbechtold]

Let me know if you figure out the airbag resistance. I've searched but have not figured it out.

 

[BMThiker]

Does being in 4hi or 4lo (vs. 2hi) change the thresholds for those life safety systems?

 

[Sam Stewart]

You should never run a resistance test on ANY airbag related component. It could easily damage it or set the air bags off. To run the resistance you have to send a small amount of current through and that's all it takes. There are no specs on it bc you can't test it. Any airbag related components have to be replaced if anything goes wrong with them including wire harnesses. Can't repair those either. Toyota (and I'm sure other manufacturers) take safety systems VERY seriously.

As for the thresholds changing I'm pretty sure that's a negative.

And just on a side note I've been with Toyota for a relatively long time and I can tell you that you have to absolutely CREAM a Toyota to get the airbags to go off. There are sensors on the frame rails, yaw rate, side impact sensors, etc. They will go off if it's a bad enough collision but they don't want them to just go off while you're in a parking lot and hit a speed bump (cough... Ford.)

Anyway, just thought I'd chime in with my personal thoughts on the matter.

P.S. Awesome build btw. Can't wait to see some pics of that beast on the trails.
