    If it is stock, then you have an open differential.

    :( does that mean that only one tire has power all the time it or does it switch back and forth.

    sorry for reviving an OLD thread (and also for thread-jacking) but I have the same Taco as the OP and am about to buy a LSD to help me out on them dusty trails.

    Some people run TRD LSD's, while others prefer TrueTrac. Is this purely personal preference, or is there more at play?

    Thanks.

    The Eaton / Kazuma / TRD LSD uses clutch plates, which can eventually wear out and need replacement. It's also advisable to add friction modifier to the differential lubrication to help with clutch engagement.

    The TrueTrac uses helical gears (no clutches). In theory, they don't wear out and don't require any additional special lube products.

    Thanks! That's exactly what I needed to know.
    Looks like TrueTrac is the one for me!

    This video is outstanding. I always kinda-sorta knew how the differential did its thing but this video makes it completely clear.

    So my question: I want to order a BAMF diff skid and he's got 8" and 8.4".

    My '02 3.4 4x4 SR5 has the 8" correct... ? (no locker, 4.10 gears)

    Thanks all!

    No

    8'' is the Elocker

    8.4'' is the open.


    technically both are still 8'' rings..but the 8.4'' is SLIGHTLY bigger. The pinion is supposed to be stronger too or something..

    either way. You want the 8.4''

    So when we talk about an 8" vs an 8.4" diff, where exactly is that measurement made ?
