Differential & Transfer case Gear Oil

Unfortunately no longer in PR. Now in Miami.

Yes. Replacing them is very easy...

 

Replaced all three, both differentials and transfer oil. 45k miles. For how the oil looks, rear diff shall be replaced at 30k, front was ok, but transfer case oil was like new.

Truck use, couple of moderate off roading, the rest normal road and highway use.

 

"Do" the TB and MAF? What do you mean? Replace them? Clean them? Buy them candle-lit dinner?



Thanks,

Clean them.

Then light a candle, grill a steak, crack a beer and enjoy it on your tailgate

 

Just changed my 2015 Toyota Tacoma TRD Sport 4X4 front differential, rear differential and transfer case gear oil with Mobile 1

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

75W-90 in the link: t.ly/J3kWv along with replacing the crush-washers found here: t.ly/dN2YD

Truck has 44518 miles on it. Was an easy project to complete and no issues to report. Plenty of videos on YouTube to follow or follow information provided here.

Love saving money and knowing the fluid change was done correctly.

 

I thought only TRD off road had rear LSD. So TRD sports have them too?

 

Yes, the sports have the LSD as well but the 09+ models have the auto LSD where the pre 09 had the mechanical LSD.

 

I used Redline 75w90ns in both front and rear diffs and the transfer case.

 

I have an 07 with the mechanical LSD. From what I've read, it's best to use conventional 75W90 because of the mechanical LSD. After doing some research, I still have two questions:
If the 75W90 already has the LSD additive do I need to add more?
Can I use the same conventional 75W90 for the rear diff, front diff, and transfer case?

Thanks for the help.

 

Doesn't matter if it's conv or syn just make sure it's 75w90 or better.

Doesn't matter if it has the additive or not add an 8oz bottle of friction modifier to the rear and when done find a lot and do some figure 8's to work it into the clutches.

Doesn't matter if it has the additive or not it's ok to use in the front and transfer.

 

I ended up taking mine to the dealer for this service. The mechanic said I do not have the mechanical LSD and that he used the same

$30 Mobil 1 75W90 Mobil 1 104361 75W-90 Synthetic Gear Lube - 1 Quart (Pack of 2)

Mobil 1 75W90 for the transfer case and both differentials. That was 9 months ago and I haven't had any issues with the fully synthetic Mobil 1 75W90.

 

30K on sparkplugs is overkill. I've done them at 50K and they've still looked pretty good.
On the brake fluid thing, I bleed mine every couple of years and dump in some new fluid. I don't do a complete flush, but a good bleeding (use fresh leeches), until the fluid comes out looking cleaner, should be sufficient to extend the life of the system.
I'm at 143,000 on stock coolant with no problems. I checked the conductivity a couple of weeks ago and I'm still really low. I'm skeptical on this one so I'd get various opinions and make your own decision. I think changing coolant at 45K is crazy and a waste of money.

 

Can I use this stuff in the t case and diffs of my 2015? I had it leftover from my first gen. It's gl4.

 

Absolutely, but in my opinion it's overkill for the diffs. I'd use it in the transfer case and buy something a little less expensive for the diffs.
It will work just fine.
