I am actively looking for a 3rd generation 4Runner and saw a 2000 Sports Edition SR5 this morning.

On the Limited, there is a button that reads "RR lock" which is obvious.

However, on the SR5 that I saw this morning, by about the left knee level, left of the steering wheel there was a button that had the identification of a four wheel drive drive train, with the front axle, front tires turned to the right, there was an "X" marked by the center differential (transfer case), and the showing of the rear axle.

I asked the salesperson, he didn't know what the heck it was. I am guessing that is the E-diff locker.

Am I correct?

Thanks all!

 

Thats the center diff lock i believe.

 

It is the center diff lock, the Rear diff locks will have the RR Diff Lock button near the dimmer and also the rear axle 3rd member will have a small motor on the outside with some wires leading to the interior of your car

 

that button turns your IFS into a SAS.

 

Thanks, in that case then the search is still on until I find one that has the RR dif option.

By the way, if I decide to change the R&P can I still use the E-diff or I have to switch to aftermarket lockers?

Furthermore, with a 3" lift and going with 33's using factory 16" wheels, do I have to use wheel spacers to eliminate body rub? Or should I just go with the inner fender trim approach?

Thanks all.

 

dang ur needy. hehehe.

 

If you decide to change gears the e-locker is still usable. With a 3inch lift 33's will clear no problem. Some ppl have had a little minor rubbing with the wheels stuffed on stock rims but others have had no problems whatsoever.

 

what is ifs and sas... i have the button he is talkin about on my 4runner

 

Independent front suspension

Solid Axle Swap

 

so what exactly does the button do when pressed?

 

ya its the center diff lock from my understanding they dont really do much. get the rear if possible.

 

RR DIFF LOCK, locks the rear diff together, both wheels are turning at the same speed, but open diff will spin the tire with the least amount of resistance i.e. the one in the air, mud, snow. the rear locker is like having one solid piece connecting the two sides, instead of 2 separate pieces

 

To clarify, if you have an open diff (no diff lock) the power goes to the path of least resistance e.x. if one tire is in the air, it will get all the power. When the Rear differential lock is engaged, both rear tires receive 50% of the power, regardless of the traction (you could have one tire off the ground and the other would still get 50% of the power)

 

im still confused on what the button does (not the rear rr dif lock button)..the one described in the first post

 

It locks the center diff, which means the front and rear will both get 50% of the power... but the left and right sides are still open, so a tire in the air will still just spin on that axle...

 

so if i dont use that will the tire in the air still spin?...it sounds like its just the same as putting the truck in 4wd.....

 

no..in 4wd w/o center diff lock, you will have and open tcase..just as you would have open diffs. center diff lock locks the tcases (front wheel & rear wheel drive) together, so they each get equal power.

 

so when not activated all the power goes to one rear wheel and when i push the button half goes to the front and half to the back?

 

Yeah basically.

In 4wd, with open diffs, you actually are running basically in 2wd if you have two wheels in the air. A true 4wd has locked diffs, and all 4 wheels are turning at the same power/revolution/time.

 

thats gay.. so my 4wd is actually 2wd cus only one in the front and one in the back get power... and that would mean that this button does the same thing as putting it in 4wd right?
