Fluid flush

New to the forum, have a 2019 tundra about to hit 40k miles, regular oil changes around 5-7k mile. Recently change the rear diff and brake fluid. Wondering when to change rest of the fluids ?

Jump to page 38 and there's an entire schedule laid out for ya. This is Toyota recommended so going sooner wont hurt.

 

30K on the front differential. I was going to wait until 50K but I'm at 30K now, so I guess it's time.

 

30,000 intervals on Front, Rear, and Transfer. However, if you don’t regularly use it, then you can stretch it a bit.

I just recently changed mine and it was still very clean. Didn’t use it that much this past Winter in CT.
