What service to perform at 37k?

I have a 2014 with 37k miles. It needs an oil change. I should do it myself, but am also thinking about doing the diffs. However, I’ve been so busy with work and the kids sports, that I’ll likely get the dealer to do the work. We tow a travel trailer so i’m Erring on the safe side. Question is what work to have them do?

Front and rear diffs?
Transfer case?

Anything else?

 

I do my engine oil every 5k, diffs around 30k. I did my transfer case at 47k along with the diffs again and the transfer case oil was pretty dirty. I guess it depends on how you use your truck.

 

I would have them perform whatever is due at 40K miles.

 

The rear diff. I just did mine. It does a lot of work. My oil is due and i am going to change it and the front diff at the same time. I have a 2014 with 37000 too. They say the transmission too. Mine had a leak that was fixed. They replaced a good bit of oil then. I am going to let it ride till next time. I am saving up for the transfer case oil. It is $$$$$.

 

the transmission fluid is rated at 100k for "severe duty", lifetime for "normal duty" - on my last Tundra I had it done at 50k, at around 110k when I bought my new Tundra, there wasn't a noticeable difference in the actual gear changes (the transmission software seems to have gotten much better from 2nd to 3rd gen though) - that leads me to believe the 100k interval for "regular driving" may be good

 

Diffs, transfer case and Brake fuid believe it or not, Toyota recommends flush at 30k

 

Thanks all.

 

I use full synthetic German Ravenol.

*HINT: On the oil guide you must select "car" to get you to select the Tundra model.

This will tell you all your fluid change scheme.

 

I changed transfer case at 50k on my Tacoma and it looked brand new. I see no sense in changing transfer gas at 37k unless you use 4wd a whole lot.

 

I agree with this, my Tacoma was the same way. But the Tundra could be different I guess, now rear differential is a different story. The rear diff fluid looks pretty dirty at 30k from my experience.
