30 K service

I have 2021 4 Runner with 30k at this most recent service ( oil change and tires rotation) the dealership gave me a huge list of recommendations. I’m wondering what other owners recommend at 30k? Thanks
They are telling me brake flush, steering flush, mass air flow cleaning and fuel induction service.

 

I would follow recommendations from vehicle manual or from Toyota website.

 

No, No, No, No and No.

 

This Toyota dealership:

 

This was a somewhat comprehensive maintenance map from a post (I forget if it was here or another forum)

 

What does your manual say?

 

Depending on how you use your 4runner, I would do a front and rear diff oil change. If a pavement queen you could probably wait til 60K. But just by age, I would change it now if it were me. Dealers just trying to make money off of you. In 40 years of owning Toyotas, I've never used those "needed" services.

 

Toyota 2022 Warranty and Maintenance Guide:

 

Those (other than fuel induction, MAF) aren't bad to do but might not be a good value.

If it hasn't been touched before, I'd do the front differential, transfer case and rear differential, brake fluid.

I did power steering and coolant too but that's a little above-and-beyond.

 

This is not an Honda SUV.
Maybe an overkill for a street vehicle

 

So the dealership is so expensive and I’m not mechanically inclined. I contacted a local reputable transmission shop and they use Valvoline Max and Full synthetic gear line.for transmission , differential and transfer case. Do you need to use OEM fluids? I’ve seen YouTubers stating you should. I don’t want to wreak anything. Thanks again

 

If it meets spec, and sounds like they do, I would not worry.

 

Valvoline gear oil of the correct viscosity is fine for front and rear differentials.

The transfer case has a synchro that can be damaged by the incorrect oil, so buying the expensive transfer fluid from toyota is the only worry-free option.

The transmission costs a ton of money to replace. It can be damaged by the wrong fluid. Toyota transmission fluid is not that expensive; so there is no need to use anything different.

That said, I wouldn’t do any of these at your mileage; especially if you’re paying to have this done.

 

OEM for transmission is the best route.

 

Do not forget the drive shaft u-joint zerks and slip joint zerk.
Very few vehicles on the road have grease zerks.
Maybe your dealer technicians have never been shown how to properly grease a drive shaft on a 4runner. It is possible to damage the u-joint grease seals and overfill the slip joint with a powered grease gun. Most shops only have powered grease guns. A pistol type hand grease gun can easily do the job.
Find a mechanic that knows how to lube a drive/propeller shaft.
Note: front wheel drive vehicles (almost all cars on the road) do not have grease zerks.

 

My 2020 4R just hit 50K and after considerable research, I decided to change fluids as follows:

Transmission drain and fill. Toyota ATF-WS ONLY! Transmissions are picky.
Transfer case… same story… Toyota 75W transfer case fluid.

Front and rear differentials… Amsoil 75W-85 (I just like Amsoil products)

And, of course, engine and cabin air filters, engine oil and filter.

 

At 30k I’d change the engine oil and the filters. Lubricant the propeller shaft. That’s it. Maybe the diffs and transfer case fluid. I did use Toyota’s liquid gold for that.

 

They advised you of the least important stuff. (except maybe the brake flush)
)brake flush goes by mileage and age as it absorbs water (about 3-4 years_

more important at 30K
1- change rear, front diff fluid and tarsnfer case
2- grease all zerks of drive shaft (do these every 15K-30K if you can)
3- air filter and cabin air filter.

at 50K , I would do transmission drain and refill, coolant flush.

drive it for another 50K

power steering flush is really low priority, do not touch MAF ... great thread...
