    Correct, but the "LS" on the Mobil 1 gear lube denotes that it is safe for use in LS diffs...It doesnt have any LS addatives in it.

    Well, that clears that up ! I used Mobil 1 LS. They told me it was OK but I didn't know it didn't have LS additive. Thanks.

    Thanks for the great write up of changing the rear diff oil! I used to do all my own work but lately gotten a bit lazy, this inspired me to DIY!

    BTW dlr wants $59 to do this. I did it for ~$20 and 20 min, and I'm sure they don't use Synthetic.

    I used 2 qts Mobil 1 Synthetic Gear Lube LS 75W-90 ('00 2WD non-LS).

    This oil went in very easy, I warmed it for 10 minutes in a pail of hot water, just passing that old trick along if anyone does it while it's cold (not that it is cold now).

    Hey Chris! Thanks for the write up! I did mine today and it was so easy:D! $23 later and it sounds way more quite and more pick up and go!

    It was as easy as you said it would be!


    Thank you very Much!:D:D:D:D

    WOW!!!

    I just read 32 pages of this DIY...and it reads part like a service manual...part like a novel...and part like a reality show. LOL

    I only have 2100 miles on my SR5 Tacoma...and I can't wait to tackle these gear oil changes.

    I also have 2 years/25K miles maintenance included with the truck...but I'm still gonna do this myself. I love it! I've already changed the motor oil with Mobile-1 and a new YZZD3.

    Thanks Chris...this forum rocks...is addicting...and I have not been this motivated to wrench on a truck in years.


    :cheers:

    OK...I'm somewhat confused...

    I checked and my rear-end has a C3 sticker and no LSD sticker.

    However my window sticker says I have "Auto LSD"

    Can someone clarify???

    The "Auto LSD" uses the brakes to give traction to a tire needing it. You do not need an LS addative in your rear diff.

    Sure. Mobil 1 is a good gear lube, and readilly availible.

    I just soaked both the fill plug and drain plug with a little wd-40 a day before I removed them and they came out with little effort.:)

    I need a quick answer here guys .. hopefully someone is online that can answer this. For the rear diff I filled it till I saw gear oil coming out the fill cap then put the cap on .. waited and came back and filled it till it came out again.

    My question is.... Do I use the same fill method for the front diff and transfer case????
