Default Broken rear pinion

First trail breakage. Now I'm wondering what I need to do. I have a coarse spline pinion on my 4:11 setup currently. Thinking about options:

1. Get a new ring and pinion (and bearing? other stuff?) and put it in my current 3rd member, but I think that requires expertise in setting up gears right?

2. Get a whole coarse spline 4:11 3rd member and stick it in.

3. Get a fine spline (late 4:11 model FJ40 or FJ62) pinion and ring set and put it in my current 3rd member.

4. Get a fine spline 3rd member and stick it in.

Not knowing anything yet about full-floating rear axles, but thinking that sometime down the line I would like to go that route with Toyota cable lockers, does anybody know off-hand if there are any compatibility issues with those components and a 3rd member that they would be installed in? I cannot come up with any reason why there would be issues, but...

Aftermarket gears will be your cheapest option plus they will be fine spline! Of course that would mean you need to decide how big of tires your gonna run then you can get the gear ratio you need but that also means x2! Decisions, decisions.....

Another thought....Treeroot will be swapping out gears soon and I think he running 4:11 fine splines.....

Fastest and easiest would be to drop in some course spline 4.11 chunks. Doesn't ige have like have a dozen?

The fj60 has 3:73s and there are two? spares of 4:11s under the workbench. The 4:11s will be coming out of the 40 as soon as I get around to wrenching again...

I'm thinking I will want to go with the fine spline 4:11, Mike do you know what flavor the ones on the workbench are? And in your 40 are they the fines?

If you go fine spline, you'll need to either change out the pinion flange or swap to a stub shaft from a fines spline driveline.

i have a (few) 4.11 course diff if you need one.

Fine spline was 12/78 FJ40 only and I think the FJ62 had some. Everything in the garage is coarse spline

Some late production 77's had it also. All 62's are fine spline 4:11's! 80 rears are also fine spline 4:11's and will fit but are designed to be full floating so a c-clip relief must be machined on the side gears or of course do the full float thang. Early FJ-80's with semi float rears are direct swap.

I've also kept the gears that came out of my 80.. they will be a lot like the gears that Treeroot takes out of his 80. Matt you can have them if you want to go that route. Yes it requires some skill to set up gears, but it's nothing a lot of folks in the club can't handle.

But why rebuild your axle, why not just swap the whole thing? Would you be happier if you had a set of 60 axles under there instead? Like here's a set.. comes with a backup 2F & 4 speed. http://denver.craigslist.org/car/489700117.html
