150k maintenance

Hi all. First post here.

I drive a 2013 dclb Sport.
I bought it with 70k and now have 156k miles.
I have been diligent about oil changes/ cleaning air filter/ tire rotation etc. but have never touched anything involving the differentials or tranny.

I recently lost a U-joint so replaced them myself.
Also did the Plugs. (Which I learned should have been done at 30-50k interval )

I’m just wondering what people are doing for major maintenance and what everyone recommends. I’ve heard some people say to never touch the tranny fluid but I am curious. The truck runs great still... not having any notable issues... but I’d like the keep it that way as long as possible! Love this truck!

 

Hi, friend! I drive a 2012 DCSB Sport Taco that I bought new with less than 10mi, currently at 92k and change. I don't off-road other than very casual dirt roads. I do like to redline the bad broad occasionally cause why not but I mostly drive like an old lady. I live in New England and feel like our roads are basically goat paths with the potholes!!! It lived out west in Utah for 4 of her years. I have performed the following in its life thats relevant to your post minus oil and air dummy stuff (that I can remember), so you probably need the same at minimum, please take this very anecdotally as I'm sure others will have better info:

- front and rear diffs and transfer case changed twice, ~30k and 70k. I may do again at ~110k interval just because I only use in the snow and occasionally in yard to prevent problems in between use. I used regular recommended weight dino oil not synthetic
- tranny just drained and filled, no flush at 70k
- plugs all densos at ~30, ~70, ~90k. I just changed them at 90k and they looked brand new honestly
- I 100% grease my nips. Lube up that shaft. Search on here for DCLB zerks and you'll find what you need to know. I do it every oil change who knows if it helps or not but I'm trying
- new serp belt at ~85k because I had a squeak upon start up. Was nervous it was a pulley but pulleys were fine and new belt cured it. No problems since. Old belt didn't look too bad but did have normal cracking and wear and tear. I do have tow package so was concerned about new alt etc. Seems fine now haven't heard a squeak!
- new battery in April 2018, lag on startup, I drive a lot for work and didn't wanna mess with it. Autozone said I had diminished cold-cranks so went OEM battery for $100 no biggie and peace of mind. I feel like 6-7yrs on original battery is pretty good...
- had AC recharged like 3 weeks ago since it was inop
- I just ordered 5100 Bilsteins all around for new shocks. No lift, stock setting. My rubber bushing mounts are severely dry-rotted so figured might as well replace the whole deal. Like I said, I drive a lot for work so lifting looks cool but diminishing returns.
- I'll probs do a coolant flush (should I just do drain and fill???) at 100k. My brake and power steering fluid still looks great color-wise.

I think that's it. This truck has been very good to me. It is completely stock minus new wheels/tires 'cause I'm a wimp.


Wow sorry for the word vomit, hope this is any way helpful!!! Cheers!

 

Either have dealer do a true trans fluid flush or you can just drop the pan install a new filter and topped off the fluid, I think thats about 1/3 of the fluid.
Change differential oils, easy to do, fronts a little bit harder but not by much.
Transfer case, harder then rear diff due to location but easier then front diff.
Coolant drain and refill.
Power steering fluid flush.
If you already did spark plugs you may need them again depending on what type you used at what mileage. I use Iridium NGK's and change them at 100K, never had a problem, Denso spark plugs are good too.
Drive belt not bad to change, OEM is good, Bando not bad either.
