FJ Cruisers of Northern California

REAR GEARS BUSTED (upated 9-23-09)...

So my FJ was at Toyota for a front/rear diff gasket replacement due to fluid leakage and after the parts have been received by Toyota they opend up the 3rd member and pumkin to get the gaskets in and they found my ring/pinion had 3 busted teeths and the pinion had chips so after speaking with the Toyota adviser he told me all work will be WARRANTED.. :-) Lucky I did not blow my gears on the trails and this had been found while at the dealers hand. I went to Toyota to look at the rear and got out of the elevator and found the FJ all apart.. I was like wow wish I already had 4:56 gears so they can swap it, it was nice of C/T to show me how the gears look and let me take pictures and the following is a pic of the rear gears that got busted.

UPDATE 9-23-09
Went to Toyota to drop off new front wheel spacers and the new 3rd member came in and alread been installed just waiting for other parts to be put back togeth. Picture of new 3rd member is below and a.s I have notice that the rear lockers have been replaced. :-) whoo hoo...

(UPDATE 9-17-09)
Spoke with the Toyota adviser and said that my FJ will not be ready till Sept 25th.. :-( due to the 3rd member that is coming from the East Coast. Good thing they gave me a loner last Friday and been driving a Prius it was fun driving it but I went in and picked up a V8 4x4 4Runner for my trip this weekend...

I'm happy that it got covered, and the gears probably broke awhile and just never notices it till they open the pumkin..

Its crazy how teeth can break and it still seems to be working just fine !!!

Man you should have see the stuff I had to put on the track because of lack of parts..... I would cross my fingers every time they would go by Start/Finish... Some of them looked as if someone had ground down all the teeth on the pinion.. Some how its still worked !! ... Crazy man I tell ya just crazy...

I'm trying to remember if you have a Manual or Automatic.

There is a known issue that on the auto's that there was a run of gears that were not harden correctly and had a tendency to shear or break.

I haven't read of any issues with the M/T gear sets yet.

I have the AT, and I thought that I had the new gears but I guess not. My FJ was built on Feb, 07 and from what I heard is that the once that had the issue was the FJ's built in 06.
