Toyota Tundra front differential

[oldman]

I am going to change the gear oil in my 2003 Tundra. The Transfer case and rear differential use a 24 mm socket. Does anyone know what size allen socket for the front differential?
Thanks

I have a 4x4 tacoma and the front diff used a 10 mm allen. i used a standard allen wrench.

Thanks JCAL, just waiting on the oil to arrive.

oldman,

what kind and weight oil are you going to use?

Hi Par, Both Amsoil, the rear will be 2000 75-140 and the transfer and front 75-90.

I don't think you will be happy with the fuel economy drop with the 75w140 in the rear diff. Expect to lose some.

Don't know, that is what it called for in the manual. I suppose that is what is in now.

In that case maybe you will pick up a slight increase in fuel economy by putting synthetic in. Or no change at all.

Thanks JCAL, worked great. With 10k on my truck the only thing was some small metal bits on the large magnetic plug in the front diff. Other than that went smooth.
