I'm not sure if anyone has started this but I think that we all would benefit and TOYOTA by knowing your build date for all of our members that have had a BROKEN REAR DIFF. Even better please let us know your third member build date
that is stamped on the side of the third member near the E-locker.

Round two

This doesn't count! =)

So if you have or had a broken REAR diff please post up your build date and your Third Member's Build Date, with a description of what you were doing when the rear diff let go.

I'm obviously interested in finding out what build dates are at risk of a broken diff. Since mine is a 0906 build date with a 9-18-06 3rd member build date, I'm a bit worried that I might have a soft arse in my FJ. I mean soft as in it might break but seriously, as pointed out by fellow forum members the gears are breaking because they are to hard I guess, or now it appears problems with the castings. Plus, we can have this data on hand to print out or call up and show our SERVICE MANAGER at Toyota GOD forbid this happens to more of us loyal customers. Toyota should make good on their product and offer a recall or TSB on the rear diff if their and our data can prove there's a manufacturing defect with the materials used in the FJ's rear differential.

Thanks all.

I don't have the build date, but I'm about VIN# 9,600 and had a broken 3rd ring gear. They replaced it and gave me a new rear locker, gears, and housing. The good thing is that the rear lower now works in 4-Hi.

That makes me a bit nervous.. My rig is stamped 01/07..

...I'm a bit worried that I might have a soft arse in my FJ.
I thought the ring gears were breaking because they were over-hardened and brittle. Wouldn't that be a hard ass FJ? :)

I've got an 04/06 build date. It would be nice if we could establish a set of "book-end" dates/VINs for these problems.

Mines a 03/06 build date 32k miles and no problem. Is the rear diff covered in the 5yr/50,000 or 60k mile powertrain warranty? Should I ask about replacement next time I take it in to the dealer? Actually I'm supposed to take it in this Friday for FJammer problem and to check engine pulleys and to check for bulges and rips. I'll see if they can check the diff.

This making me scared!

I have the same stats except for the last one!

Built 06/06
Bought 07/06 (Same area, Tampa)
Still OK,,,, but I am scared now!

Seems to be quite a few 06/06 build dates blowing up!

That might make a difference!

Manual verses Automatic!

Who has what!

Mine is an Auto, still OK!
