100k mile maintenance - what should I do?

Nbarr7655 · July 25, 2023

My truck is currently at just over 95,000 miles and I am gearing up to do a tune up. My question is, what is recommended? Here is what I had in mind. Is all of this needed or is some of it "optional" as opposed to recommended.

Inspect brakes (should be good - I did them about 10,000 miles ago)

Drain and replace both differentials fluids

Spark plugs (do I do the wires as well?)

Transfer case fluid

Inspect power steering fluid

Inspect brake fluid

Transmission fluid and filter

Drain and replace coolant

Inspect air filter

Oil change was just done about 2000 miles ago

Inspect tie rods (did inner and outer in the last 20k miles or so)

So again, is all of that recommended, or is there some stuff that I can gloss over? I am open to all answers.

Truck is a 2014, 5.3 4x4. Everything runs fine, no issues or hiccups

Other modifications in case it matters:

High flow air filter

Borla exhaust with 3rd cat and resonator deleted

2.5 inch front, 2 inch rear leveling kit

Doing the maintenance is the key to it lasting. Being able to do it yourself is an advantage. Cheaper and you choose the products to use.

Do it and do it more often, especially fluid changes.

I started making a list then thought. Get into your manual and find the "Severe Service" schedule. You're going to find several services are WAY past due. If you've never done the transmission, I'd bet the fluid looks like mud. Ditto diff's n transfer case. I'll leave the air filter to someone else. I'm not on the menu tonight. :crackup:

Stick to your list and add a differential service, change the brake fluid, don’t bother inspecting it, it will be dark and dirty.

I have a 2014 w 86k miles on it.

im very happy with this truck, only planned on keeping it a few years but it’s been such a solid truck, I’m keeping it a while longer.

I replaced the spark plugs and did the trans service (along w changing a couple of seeping trans cooler lines at 82k

Just changed the coolant (lots of horror stories about aging Dex Cool out there) and added. A bottle of Water Wetter because of the climate I live in.

Air filter gets changed annually as well as the AC cabin filter.

Noticed the plastic portions at the connectors near the fire wall on the 2 heater hoses are starting to turn brownish which means they are starting to deteriorate.

They will be replaced shortly.

Don't overthink it, just get it taken care of.

Thanks everyone! I bought the truck used with ~45k miles on it and from what I can tell by service records, only basic maintenance was done. (Oil changes, brakes, wipers, etc.)

I will plan to knock out that list - I plan to do it all myself. I don't think any of it is too bad, is it? I have done diffs on my older truck (04 Silverado 1500) but never done the trans fluid/filter.
