Anyone flush their diffs? I know a lot of people say theirs weren’t even full or had a ridiculous amount of shavings in there.

Have you looked at your diff? There is a recall for seepage on the rear diff. You can find the Technical Service Bulletin. My diff has seepage. Taking mine into the dealer next week. ugh...

That sucks. But yes I’ve looked and no I haven’t seen mine leak.

I plan on doing it soon I’m at 40 K miles. I went to Toyota and quoted the fill bolt and Magnetic drain bolt and special Toyota sauce differential oil for 60 or something. I’ll try to find a printout it sitting somewhere in my truck so for right now it’s 60 is just a ballpark estimate

I took my truck within the first 5k and dropped it at two separate dealers to have them document that they inspected, flushed/filled, the diff. If I ever have any diff issues I've got it documented. Not to say the mods I now have won't make a warranty claim difficult. I had the first dealer fully drain and refill the diff, and the second confirmed it was topped off.

Did they look at you like you were stupid and try to say you don’t need to be doing that?

Yep. The first dealer I told them exactly what I wanted with the flush and fill and I had to leave it overnight so the truck was cold when they did it etc. The second dealer could see that I had a history where I had already had the diff checked. They looked at me like "why do you need to do this again when you already did it?" I just asked them to confirm the fluid was at the correct level and have it documented. They did and I have the paperwork from two dealers showing my fluid was good from early on in the trucks life. This may be overkill for some, but it wasn't to hard for me to do and gives me piece of mind as I plan to keep the truck for a long tome.

I did cause i have 4.88’s and yes a ridulous amount of shavings. Very easy to do and rear is worse cause you use it 24/7. Id highly recommend a pump for fluid though i will definitly use one next time

I’m surprised it’s not part of the free maintenance to do this.

Did you put anything special in or just basic gear oil?
