I tried using the search for this but I'm on my phone and the forum doesn't display correctly on it.
I have a 2006 SR5 V6 4x2 and I going to be draining and replacing the diff fluid as I don't think the previous owner has done it in a long time...if ever.
After some research here and looking at various you tube videos, I ordered 4x 1 quart of these:
Mobil 1 104361-UNIT 1 Quart (32 Ounces) 75W-90 Synthetic Gear Lube

I noticed it says LS for limited slip applications. Does that matter? Just checking to be sure!
