2003 Sequoia 2wd
How do I know if I have a limited slip differential or open ?
Does the VIN number tell ??

AznSky

I would think ur owners manual would say it

Darren

You don't have a limited slip.

Even if you did, you still change the diff oil the same way.

hatcoleman

No the owners manual does not tell you if you have LSD or open differential.
And I do know that you change the oil the same way, but with a LSD you have to had friction modifier. That is why I asked how to tell what differential you have. Does anyone Know how to determine type of differential on this vehicle ?

Hat,

Call the Toyota national customer service number, give them your VIN and they will tell you. Thats it.

Well, I told you that you don't have a limited slip. You know it's not locked. Am I missing something?

All Sequoias are open.

Just use a gear lube with the friction modifier in it. It will not hurt anything if its not limited slip. On the other hand it will chatter like hell if it is limited slip and no friction modifier.

Does my 95' runner have limited slip? The manual doesnt say anything bout it.

guys ... it should definitely say in the manual somewhere ... if not, call a dealer and ask, or do a yahoo.com search or something.

The owner's manual isn't going to specify other than if you have one type use this, the other use that. Your sales paperwork should specify, however, and Darren's probably right about them all being open. The LSD is likely an upgrade you'd have to ask for or a part of a whole trim package, but it's been some time since I shopped for new Toyotas, so that's just a guess.

The 95 Runner does not have one unless someone threw a TrueTrac into it aftermarket.

Best bet is call the dealer with the VIN...or find a place with a low traction surface, JUMP on the gas and see how many roostertails you throw - if 1, its open; 2, it's limited/locked.

Well, that last statement "all Sequoias are open" is just a little misleading. The 4X4 Sequoia comes standard with TRAC (4 wheel traction control), which exhibit most if not all the characteristics of a limited slip. In the Sequoia manual it talks about extra traction in low range and in first gear. I don't know if the TRAC system acts like an automatic locker in that mode or not but it's suppose to give you a "little extra".

You don't need to add any friction modifiers to the gear lube but if you run a full synthetic gear lube like Amsoil's 2000 series in 75/90 in both differentials and the transfer case, you'll see a half-mile per gallon increase in your mileage. Also, expect to see metal shavings on the drain plug magnate if this is your first gear lube change - the shavings will be from the "Indiana Boys" not cleaning the case after cutting the drain plugholes.

No it's not. "Open" means that the differential itself has no traction devices installed. No LSD, no locker, no Torsen, no nothing. It just has gears in it.

Electronic traction control is done electronically by actuating the brakes or changing the engine power. It has nothing to do the the differential itself.

I know you know your stuff, Joe, but in this context, open means just the diffs.

Joe

You're absolutely correct in what you're saying; my head was temporarily up my arse. I knew the Sequoia wasn't offered with limited slip because of the TRAC system and when I saw Darren's post I experienced a brain fart, it was that simple. For those not familiar with TRAC. TRAC basically prevents the drive wheels from losing grip when accelerating or tire spinning by using the car’s ABS speed sensors at the wheels to either slow a wheel down to regain grip or reduce the amount of power applied to the drive wheels. A computer accomplishes all this in a blink of an eye.
