What kind of lube do you use? :moon:

[zerowkul98]

It's time for my V8 Sport Edition 4Runner to have the diff's and transfer case's lubes replaced. Dealer wants $100 per unit, and call me crazy, but $300 for that job is a bit...umm....ridiculous. :redbrick:

Can someone on here tell me which is the best brand and weight I should purchase?

Oh, and how much for each unit?

Thanks in advance!

I like Amsoil?

AMSOIL Synthetic 80W-90 Gear Lube

Great! Thanks!

Any idea how many quarts for the entire job? Both diff's and the transfer case?

It's in the manual:


I think 75W-90 is only available in synthetic or synthetic blend.

I don't think 90W or 80W are available any more, but 80W-90 should be fine. 75W-90 might work too?

I read somewhere that it's bad to use synthetic in a differential that calls for conventional because it will cause it to leak, but I can't imagine how that would be true?

Lighter oil like 75W-90 might improve gas mileage slightly and should work better in cold weather.

The transfer case has a Torsen differential, so I would stick with what it calls for. I don't think any friction modifiers are necessary since it doesn't really use friction, but I guess it doesn't hurt if it's in there? Or so they say.

For the front and rear I can't imagine it matters much. It's weird that the V6 front calls for 75W-90, but the V8 front calls for 90W and has a slightly lower capacity. Are they different?

^^^^Yep, only Amsoil for fluids in my runner. . . . well, the coolant is Toyota.

I use Royal Purple for everything. F/R diff., trans. case, engine and coolant. I also only use a RP or K&N oil filter. I wouldn't recommend it if you have high mileage. And if you decide to use it make sure it has Synerlec.

Last time I changed them out I put Mobil 1 75W-90 in all three.

Valvoline 75W-90 Synthetic and I'll do it for $275 :biggrin2:

If you watch for Advance Auto coupons you can buy Royal Purple online and pick up in store at a deep discount.

At the time there online system even let me place multiple orders for pickup so you can maximize your discount. I did 2-3 orders getting me 40% the original price of gear oil.

That discount is great. I'll get some Mobil 1 with it.

I guess Dealerships are not consistant, I asked in Southern Oregon and it is $60 per unit.

It's NOT...urban legends never die.
