i was wondering if there was like a sticker or anything that tells you that the rear is lsd.

If you have an LSDm there will be a push-button on the left side of the steering wheel that said Auto LSD or something to that affect. Otherwise, you don't have it.

Huh? Think you have LSD and e-locker confused...(or maybe you're ON LSD, and need to share! LOL) LSD is not "switchable".

It's in the diff code. I don't remember which part it is, but do a search on "diff code" and there's a table on another site that will decode your door panel sticker.

Factory LSD is EXCEPTIONALLY rare in the US, common in Europe.

You're looking for a 3 or 5 on the end. It seems safe to assume you don't have a factory LSD. The only person I've ever heard of is Blizzard on here, and he's in Spain. Never heard of anyone in the US with a factory unit (plenty of people with aftermarket ones though)

Why do you ask? You spin both wheels in loose stuff, or just one?

i know i dont have one, i was just wondering how rare they were, like if i could find one in a junkyard. it sounds like thats not gona happen.
anyone know of a good source for aftermarket lsd's?

I think for that you could look into a detroit truetrac, because it is clutchless, and works like an open diff on the road. I am hoping to be able to affod one someday, but thats probably not going to happen, so I must just drool.

If you find one in your local yard, GRAB IT! Then run to the hills since most any Toyota owner will hunt your ass down and probably kill you for it!

I may be wrong but I think they were more common in Landcruisers than the trucks. I have never seen one. I looked at many tags in many junkyards and never found one.

The LSD rear diff has a sticker on it.

FYI:
I have an LSD rear diff in mine. It really does not lock up hard enough to get out when you're stuck. In sand or in snow it helps a little, but it's not a good substitute for a real 100% locker. I'll be replacing mine with an ARB as soon as i have the money.

I had an LSD rear diff in my previous vehicle- Daihatsu Rocky. It is not very useful when your wheels are in the air, but it helps in the snow like Freezer said. It is not worth installing-trust me-get a real locker.

My mom's '05 4runner has a button on the left of the steering wheel that says "Auto LSD" for enguaging it... Though maybe I am just confused

Well, now, I don't know about that - depends on what kind of driving you do! LSD will be a HUGE advantage over an open diff in situations where both wheels have SOME traction or NO traction. Locker can be very bad when traction to both wheels is limited.

With a clutch type LSD, you are really out of luck if a tire comes off the ground. With a gear type (like the TruTrac or TORSEN in the Hummer), there is a torque bias that basically sends a multiple of the torque the slipping tire can handle to the other side. This allows the LSD to work as a locker with slight brake application. 4Crawler has a great writeup on it.

especially when you ON factory LSD :bounce2:

factory LSD aws available up here, came standard on the limited 4runners I think... but it is rare far more common to see the e locker option.
factory lsd was also on the "pre-runner" tacoma 2wd don't know if they sold it south of the lake though aviator
