what differential fluid for my 12' sr5??

gna change my rear diff fluid in my 2012 sr5 4x4 soon..dont know what kind to use since it has the electronic diff stuff, my 2008 sr5 didnt and it wasnt LSD so it was easy on choosing a fluild..but dont know if i need to use one for a LSD on my 2012 or not??? i knew the trd's had LSD but didnt expect my sr5 to so im confused lol

 

No, you have electronic trac/LSD, you do not need friction modifier fluid unless you've added a manual LSD.

 

Agree. That is how my 2010 is. Just use your favorite brand of synthetic diff gear. I used 75w90.

 

This is what I prefer... Works for me..

 

^This. You do not have a mechanical LSD, therefore treat it like any other open differential. Use the correct weight and choose your favorite brand of oil and have at it.

I think I've been using Valvoline 80W90 for the rear diff and

$30 75W-90 Synthetic Gear Lube - 1 Quart (Pack of 2)

75W-90 in the transfer case and front diff. I believe the newer ones call for the same fluid all around though but check your manual for the proper recommended oil weight and stick to that.

 

thanks guys..thats what i was thinkin id use, but should i go for synthetic? ive thought most synthetics ive seen are all LS, like the mobil 1 in this thread, and thats for limited slip right? maybe i can find a synthetic without LS somewhere

 

The synthetics that say LS on them still do not likely have the limited slip friction modifiers in them, they're just safe to use with a limited slip. Regardless, even if the oil has the friction modifier for a mechanical limited slip, there is no harm in using it in your open differential. It's when you have limited slip and don't use the right stuff that you run into problems.

I used Valvoline synthetic on my last change.

 

Rear 4x4 or Prerunner:
Toyota Genuine Differential Gear Oil LT
75W-85 GL-5 or equivalent

 

My manual says 80W-90 for the rear and

$30 75W-90 Synthetic Gear Lube - 1 Quart (Pack of 2)

75W-90 for the front and transfer case. Read your manual, I think there was some variation depending on the year.

 

It changed in 2009.

 

Good to know, thanks!

 

No problem. Also, according to a Tundra/Sequoia/4Runner/FJ Cruiser TSB (I can't find a Tacoma one), the Toyota Genuine Differential Gear Oil LT 75W-85 GL-5 is a synthetic gear oil.

 

I have the 2011 TRD with L.S. The manual calls for 75w85. All I can find here where I live is 75w90 or 80w90. So do I use 75w90 or 80w90?

 

You don't have a limited slip rear diff.

Either oil will be fine. If I were in your area, I'd go with a 80w-90.

 

I called 5 differant dealers gave them my vin# and they tell me that I do. So I guess , Iam going to take there word for it.

 

Their word also says to use Toyota Genuine Differential Gear Oil LT 75W-85 GL-5. There's the answer to your question.

 

Unless you put it in or had it custom ordered, you don't have a mechanical limited slip. What you have is an open differential that uses the brakes to limit slip meaning one tire spins, the brake gets applied on that side, forcing the power to go to the other side. So technically, the entire system is limited slip but, for purposes of determining which differential oil you need, you do not have a limited slip differential.

 

^^^ beat me to it...You do not need friction modifiers, you have an open diff. They say you have a limited slip but its not from your differentials its from your brakes.

 

Thank you for this. Would this apply to the 2011 also? Becouse I have the sticker that is #3. Which would mean that I dont have L.S.

 

thanks man...what weight valvoline did u use? should i just get a 75-90 or go to the dealer and get some of the 75-85?
