    I'm guessing it's pretty much the same steps for a 1st gen? I don't feel like crawling under my truck.:p

    I put in 1 quart of fluid first, then the 4oz. of additive, then filled until it started comming out. I capped it off, drove the truck about 40 feet, then topped off the diff with the rest of the oil. It held exactly 3 quarts 4 oz. :)

    First gen uses the same diff, just a little narrower. I think the specs call for just under 3 quarts for th efirst gens.

    Our Wal Mart here said they will take the oil for no charge. but have not taken it there yet to see. Our Garbage dump takes it for no charge and since Im at the dump once in awhile it works for me.

    OOPS, I forgot something. I'm not sure where Chris was going to do with the old (I guess maybe I should have taken it).

    When I change my oil, I take it to the local Checker/Kragen store.

    Right on guys!

    I'm a little reluctant to changing anything other than the engine oil, but now I'll give this a shot.:D

    Did you guys use the Genuine Toyota LSD Additive? If not what brand did you use?

    Sorry to bring back an old thread but yesterday I bought Mobile 1 synthetic gear oil to change my LSD rearend this weekend. I also bought a tube of additive. I stumbled across this thread this morning and am now concerned about using it since it seems Chris had a bad experience. Has anyone come up with new results? Should I use Royal Purple synthetic or go with conventional gear oil? Thanks

    As you see in our wrtie-up, I/we chose to go with conventional 75-80/75-90 "Dino" oil.

    I have read on other forums guys having problems in the LSDs' using synthetic Mobil 1, and guys having good luck with RP. Maybe it has somehting to do with the LSD additive...:confused:

    Not having the first hand experiance from using those, Chris4x4 should be able to answer better.

    I used different combos of Mobil 1 and the Addative. I tried it with no addative, 2oz., 4oz, 8oz. Enev tried the Mobil 1 LS, which is supposed to have the addative in it or something. No luck. After a few days, the rear chirped and howled.
    Personally, If you do any towing, or get your diffs underwater, use dino oil in the diffs.You gotta change them more frequently anyway, so why spend the money. :)

    Thanks Chris. I will use the dino oil for the rear. One more reason this is such a great, informative site.
