I've searched and I haven't found anything. I'm new to monteros but not to offroading. My first question is I have a 1990 Montero LWB with coil springs and was wondering what rearend is in it and is it strong. My axle seals are leaking and was wondering if I should fix or try to find a Gen 2 SR. Im not going to be hard core offroading with this vehicle.

Welcome to your first post.
There is nothing wrong with the Gen I rear axle, you already own it. The seal is not too difficult to replace and is much less work than swapping in a Gen II axle. I won't go into the Gen II axle topic too much, because there are numerous threads documenting them. The benefits are a wider track, disc brakes and an air-locker (not like ARB).
I'd just replace the seal and wheel bearing, turn the drums, adjust your brakes and be done the same day.

Gen 1 v6 axle and ring gear are plenty strong and with a more powerful engine, the gen 2 SR is even bigger/stronger design. For the stock pose plant, the gen 1 rear drivetrain is plenty strong enough. Be sure to upgrade the trailing arms though.

Thanks guys. One more question. Can you tell me what the rearend is. It looks like a ford 9" but I know it's not.

From what we've been able to learn in over a decade of research is they're a Mitsubishi Gearset. No other vehicles use them. That said IIRC the Gen 1 v6 is at least ~8.5" ring gear while the 3.5l Montero's a have a 9.5" ring gear. HTH

it's a 9" MMC or KOYO , I'm not real sure on what plant the axle is built in, all I know is you can't break it or wear it out. Many came with LSD . Look for orange sticker in drivers door jam. The LSDs last forever, too.
Ratio is 4.625,,,that info and more is on a tag near radiator.
