Rear diff oil change question

[Diocletian]

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 https://www.amazon.com/dp/B000ONZXPK/ref=cm_sw_r_cp_apa_i_0VLGDbWWXDS0M

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

Many on this forum (myself included) have used it with great success. No issues.

EDIT: remember to take out the fill plug first, then the drain. Don’t want to be stuck with an empty diff and a frozen fill plug!

no worries. i had the same question and researched it thoroughly. LS wont hurt a thing.

It doesn't matter in an open diff like in your truck; you unnecessarily overpaid for a gear oil, though.

Ive used that several times and it appears to work well. The most recent change I decided to try REDLINE synthetic Heavy Shock proof 75w90... but only because I felt like it..
