Please, this is a great question. I want to know if I have a time bomb waiting to happen.
RoverGGM will have to answer that ...all I know is after my second diff. they told me they had a bad batch and they weren't hardened to spec. and got a different supplier...the same supplier they used for many many years on the tacos and a few other models
I have the contact info for the guy who runs the Trail Teams (trying to do an event in FL next year) and while he is a marketing guy I think a well written e-mail to him will most assuredly get into the correct computer at Toyota. If you explain to him you were out with the TT (& that one of the teams rig suffered a similiar fate on the same trip)when this happened learning how to take your rig off road with a Toyota sponsored event I would wager that you WILL get it repaired at no cost and you might even get to F*&k over the crap dealership you are dealing with. PM me if you want his info. K
P.S. I had a buddy blow one up on a hill last week that 20 of us have been up many times in FL and Wesley Chapel Toyota was happy to do the work under warranty.
I also contacted the dealer I bought the FJ at (Augusta) as well as Atlanta Toyota. Atlanta Toyota has already fixed a few that I know of, but Gainesville complained to the regional manager so no other dealer in the area will touch it now. I called toyota directly and they said they'll get back to me tomorrow. Out of the 3 dealers and corporate people I talked to, nobody knew there was a problem with FJ diffs, even Atlanta Toyota said they've only replaced 2 and those were the ones that I knew about. This whole thing is sketchy to me, but the way i look at it is I have a truck that's a year old with 19k miles on it falling apart. Toyota needs to stand behind their products offroad or not, at least until the standard warranty runs. Here are the pictures of when it broke. Several other FJ's made it up it fine, mine didn't. On the bright side, i made it up with the help of my winch.
What do you do after the DIFF goes out. Do you trailer it out or do you drive out? Do you fix it on the trail?

Over and out. OME lift, Steelies on 285 BFG's,Bud-built,Airaid,Demello bump & slider.

Depends on how bad it's busted. If you only lose a few teeth....you can usually drive out unless the trail is REALLY bad...in which case, the ring and pinion will be significantly weaker due to the missing teeth and will likely start to shear teeth that are next to the broken ones. It will likely get progressively worse as you continue loading the gears....so easy does it until you can get back to pavement (assuming the initial failure isn't catastophic).
If you do blow it so bad, you can't move it, take out the rear driveshaft and run it back to pavement in front wheel drive (assuming the trail isn't so bad that you have to have 4WD to get out). If front 2WD doesn't cut it.....you may have to leave it, get a built third and come back to it if another vehicle can't help you make it out without the rear having power.
HTH,
Sean

I've done this before (not with the FJ) and it works just fine. Disconnect the drive shaft, throw it in the back or on the roof and drive home. As Sean said, the only problem comes if you're in the back of nowhere. That's why it pays to go with at least one other rig.

You can't drive an FJC for long or fast on a broken rear diff. even without the drive shaft...
That's unless you live very close to the trail.
You do the best you can to get on pavement and hope for the best.
