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.

 

Here's the link:

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
