differential/transfer case fluid.

was looking to do my diff and transfer case fluid change but don't know what type of oil to use. any help? I seen may people say about adding LSD additive because it starts to make some funky noise but I want to be sure what works best for y'all. thanks in advance!!

 

What does your owner's manual say?

The front diff drain bolt will likely put up a fight. Hit it with PB blaster a few time a day ahead of time.

 

sadly it didn't come with one when I bought the truck.

 

to be quite honest, just use walmart super tech 75w90 gl5 for both, best bang for your buck, no additives or artificial flavorings, its also Gluten free

 

I got this from the 2011 manual

 

I used

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

75w-90 myself. No one had 75w-85 at the time I needed it.
And I needed it QUICK, My axle seal was leaking and had to be fixed ASAP.

 

doesnt matter what gear oil you use (LSD additive wise) in 09+ trucks, was only 05-08 trucks that got the clutch pack LSD.

That stated i use

$30 mobil 1 75w-90 synthetic gear lube - 1 quart (pack of 2)

mobil 1 75w-90 or valvoline 75w-90 that both have LSD additive in front diff, transfer, and rear without issue.

Clean oil is the best oil you can put in the thing.

 

I have been using REDLINE brand 75w85 just in my rear diff. but honestly the price point versus super tech is too high, I will be using super tech in everything now, I change them out every 30k miles, if money weren't an issue id probably stick with redline

 

I did my front/rear/diff about two years ago on my 2010 with

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

75W-90 SuperTech synthetic and haven't had any issues. I was probably at around 120k and pushing 160k now. Need to verify, probably due again soon.

 

Well we can fix that for you.

Merry Christmas

 

jup, im going there, super tech has been verified as being as good as the boutique brands,cant beat the price and availibilty

sound good peeps! but let me get this straight, so I can use the same type of oil for my transfer case and diffs ? that has LSD additive?

 

yes, as long as its a GL5 which it is

 

Yes, get 6 qts of 75w90 and you're good.
A few things I learned when I did mine - front diff bolts will put up the most fight, PB Blaster. If you get the truck up on four ramps it will be level and you can sit cross legged under the truck, makes like much easier when you're pumping the fluid into the fill hole.

 

if your doing just the rear and transfer case get 2 new gaskets for the rear diff. you can reuse the transfer case gaskets. 2 of these Toyota #

$22 12157-10010 Toyota Oil Drain Plug Crushable Steel Gaskets Set of 10 OEM 12157-10010

12157-10010 crush washers, and a 24mm socket to remove the bolts

 

Do yourself a favor and spend the extra money on new drain and fill plug gaskets i didn't replace mine when i changed my front fluid and about a year later it had a slight seep from it. Adding insult too injury the old gasket corroded to the differential and made it a pita too get off when i had to redo it.

 

I just completed this service. 6 qts of Valvoline 75w90 with LSD in both diffs and the Xfer case.

Get all the gaskets for the fill and drain plugs. You may also want to get a front diff drain plug, it can be a bugger to remove. You will also want a hand pump.

Please do yourself a favor for the next service interval, use a little anti-seize on the plug threads and DO NOT OVER TIGHTEN.

 

Also dropping the spare (cus it should be cycled anyways) helps with the rear diff and you wont need a pump.

 

I use Amsoil Severe Gear 75w90 in front, rear diffs and transfer case. No issues
