Correct me if i am wrong. At 30K the F/R diffs and TC should be changed. How about the AT fluid? Already at 30K or could you let this go till 60K? Is anyone really changing their brake fluid every 15K?

I want to keep up with these things, just not overthink them. lol. I am currently at 18,500K
Replaced the cabin filters monday. They were not too bad. I think they could go every 30K.

Should the fluids be changed at 30k? Probably. Do they need to be? <shrugs>. With an AT, do the fluid changes now, or you may have problems doing a change later. My rear diff probably went 150k without being changed, but it was never submerged either. Oh, and the diff fluid still looked like new.

Changing the brake at 15? Brake fluid is hygroscopic, meaning it will absorb water. Since water turns to steam at around 150* lower than brake fluid, should you do a lot of hard braking, you may reach a point where your pedal softens up or you flat out loose your brakes. Now, I believe that if you keep your fluid topped off, and bleed out the fluid from the caliper instead of returning it to the master resivoir when you change your pads, you'll be fine.

Am I wrong? Maybe. In the end its your vehicle, so maintain it as you see fit. There are thousands of cars in the road that only get engine oil changes and that's all. And I bet they only get that done because the sticker on the window or the computer tells them to.

i changed my front and rear diff fluid and xfer case fluid at 40k.
the front diff was pointless. still pink and perfect. rear diff was still brand new looking but the drain plug is a magnet that attracts all of your differential shavings, so i am kinda glad i did that so i can get all the shavings off. the t case was pointless as well as it was brand new looking.

i DO want to do my tranny fluid though. it feels like it could shift better.

I think you can never be to careful with changing ATF. Especially with the problems earlier 2nd gen Xs had. On my 09 I had the diffs, xfer case, and trans changed at 30k. I'll be doing all of those at 30k again on my 2012.
