    just read like 10 pages of changing rear end fluid in my 2009 tacoma sport,dealer wants 70 bucsk a quart(takes2.5 quarts)theirs has the lsd additive already added,after reading posts several different weights and oil types being used. What is a good gear fluid to use but more important because they don't sell the lsd additive where can I get it?

    Wait for others to chime in, but I don't think you have the mechanical LSD in yours. The 2005 to 2008 have a mechanical LSD, 2009+ use the brakes to mimic LSD. Does your Owner's manual, or the sticker on your rear differential say that you need the LSD additive?

    Regardless, you should be able to pick it up at an auto parts store. Any quality, name brand oil with the proper weight will do, just confirm on the LSD additive.

    You don't have a mechanical LSD unless it was added after you (or original owner) bought it. The factory mechanical LSD was discontinued after the 2008 model year.

    no LSD additive needed after the 08's since as others have said, the truck has a computer mimic LSD using the brakes. Just standard gear oil is fine.

    ^^^This. I have one of the earliest model 2009, bought Sept 2008. There is no way I have a mechanical LSD. The factory didn't screw up an put mechanical LSD in +09 Tacoma's even in the first models of '09.

    If some how you go royally screwed over on the year of your truck, as in you were sold an '08 as an '09, then you're gonna need LSD additive. 09+ doesn't need it b/c of the traction control system uses the brakes to mimic the function of a mechanical LSD.

    If your 09 has traction control, you have an electronic LSD so therefore no need for additive. Also, it is perfectly fine to run a gear oil with LSD additive already mixed in even though you do not have a mechanical LSD.

    Also, don't listen to the dealership. This site is much more informative, honest, and usually, RIGHT. The dealership tried telling me that my weather techs go on top of my carpet floor matts, that the colored headlight bulbs they sell in the parts dept. are H.I.D., and I needed new brakes at 55,000 miles b/c the fluid in the reservoir was a tad low, even though at 50,000 miles, my personal inspection showed I had 60% pads left up front.
