    I was talking to a service Tec at Toyota in a big city and he told me that the drain and fill plugs were "pressed on" and I would have to take it to a machine shop to remove???

    I have a 99 rear drive only SR5 PreRunner

    On one of rear wheels the diff fluid is leeking on the rim of the wheel.
    Can I add some as I have to drive 600mi next day.

    None yet.....
    So just so I get this right, if I have the TRD Off-Road package and not the Sport Package, do I still need to add LSD additive to the rear diff when I change the fluid?

    Also, is it GL-4 or GL-5 fluid that should be used in the diffs/t-case/manual tranny? I've seen both listed in different places.

    I just tried this service for the first time, following the thread exactly. My rear diff took about another 1/2 quart more than the stated 3 before it started to leak out the fill hole. Is there any reason for this? Is there such a thing as adding too much fluid?

    Sorry to repeat the question. I just saw this. What is the harm in putting too much? I just added a little more before reading this.

    Should I drain off the extra 1/2 qt. before driving?

    Too much oil can cause the oil to cavitate in the differential which could lead to overheating and burning up the gears.

    I drained off the extra that I put in, but then driving today, i swear that the truck feels sluggish and heavy. Is it possible that this is related? Or am i being paranoid?

    x2, but I believe I read where someone stated for the '09 and up don't need the LSD additive b/c the brakes are used as the LSD instead of the clutches

    I just did all my fluids this weekend at 30k. The fluid itself looked half decent but it sure smelled like ass. And the drain plugs magnets had a lot of sludge caked on to them. I noticed the transfer case didn't have a magnet though, I wonder why. I also noticed of all the fluids drained that the tcase and the tranny fluid looked the cleanest.

    Obviously keeping up on the fluids is a good thing. But if you have not changed the fluid in a very long time.. Ahem!.. about 75,000 miles. Would you notice any change in the drivability?

    When I changed mine out at 50,000, I noticed a pretty big difference. But I also had a 6 speed so the biggest thing I noticed was easier shifts lol. Can't hurt to change it.

    You only have the LS Diff if you have the LS Diff sticker on the back of the diff.
