Diff plugs torque

[Leandro]

Hi all
I have a 99 LX and this weekend I'm embarking on the TX & diff oil change.
My truck has LSD in the back and the plugs are not allen, they are Hex.
The FSM i have is for 2004 LC, which doesn't have the same diffs I do (cover is probably the same, but i prefer to err on the safe side). I've been also looking around and cannot find the right torque for those plugs.
Does anybody know the proper torque?

thanks in advance

I believe it's 35 ft lbs. I'm also pretty sure that the stock drain and fill plugs are all the large, shallow hex heads. The round Allen bolts are from another Toyota application that are often used to replace the factory plugs.

@Leandro - main page of 100 series, there is a thread titled 100-series FAQ. Many many sections there, 3 of those being front, center, rear fluid change, fluid capacities, and torque specifications.

That FAQ thread has a wealth of knowledge, worth doing a once over in my opinion. Teach a man how to fish

I read the faq several times. it's based the allen type plugs, which I don't have. Actually bought a 10mm allen based on that thread, my fault for not checking first.
i prefer to ask twice and not crack a diff cover.

I found 39 ft-lb

Differential drain & fill plugs 36ft-lbf torque.
Transfer case drain & fill plugs 27ft-lbf torque.

Notes:
Washers (gaskets) are not reusable.
Front differential use allen-wrench (hex) on plugs, make sure to get allen-wrench in deep and tight!
When filling case(s) let gear lube settle for 5 minutes, then recheck level. If more lube is added repeat.
I like M1 75-90 synthetic gear lube LS.

Any reason to use the 75W-90 in the front/rear diffs instead of the 80W-90 in the manual?

I noticed when I was filling mine that I would end up getting a little bit less than the stated volume of fluid. I stopped if it started to flow out the fill hole. I suppose that's from residual fluid on the gears and whatever doesn't drain from the very bottom of the carrier?

KiISS. Also when using synthetic you've more wiggle room on viscosity (low & high numbers). FSM & OM viscosity are based on conventional oils & gear lubes.

Thank you all

Due to the amount of fluid in the rear, I would pour the fluid in vs pump the fluid in. The pump comes in handy for the front/center fills.

Maybe you missed this part in the thread?

Notes:

1. Verify plugs are 24mm hex head; could be 10mm Allen head (requires Allen socket to use torque wrench) or other size

the hex is a 10mm for the front diff, 24 mm hex for the other drain and fill plugs. before you crack the drain plugs loose make sure that the fill plugs will come loose as well, don't drain it if you cant fill it. I only made that mistake once.
