150K Service Essentials

Depends upon what has been done up to now. At 125K, I changed out the serpentine belt (2nd change), idlers, water pump, t-stat, radiator, all hoses, transmission flush and fill, transmission filter, oil and oil filter, plugs (2nd change), differentials and transfer case fluids and some other more minor maintenance items. This is an 03 that I've owned since new with regular maintenance. Everyone picks a mileage at which to do all these things, hopefully not waiting for a water pump to fail, overheat the engine and blow the head gaskets. I fear losing the all too common #6 cylinder so try and keep everything as current as humanly possible.

Done at 100K. Was told transmission fluid is lifetime?
Brakes done at 94K replaced at 117K *****ed at dealer about that now at 150K brakes are fluttering again....granted pulled a trailer from San Diego last year and Seattle is a pretty hilly city....originals lasted 90K miles....pretty terrible the replacement OEM pads that Toyota put out.
They will inspect hoses, belts battery was replaced at 120K on original.

How may miles do you have now?....did you elect to replace the water pump?
Now at 130K and yes replaced the water pump since removing the radiator and its shield opens everything up and makes it all easy to get to. Ditto for hoses and transmission lines as well.

Technically a true statement. If you run the fluid to failure, that defines the lifetime of the transmission.
When I flushed mine at 165K it was brown, and the transmission shifting was harsh. After a ~14qt flush with WS the shifting was smooth and positive. Unlikely that brown fluid full of contaminants was doing the solenoids and bearings any favors.
Knock wood, I've never had an automatic transmission fail on me. They get flushed every 40-50K miles. When I bought the 4Runner at 164K very neglected miles, flushing the trans was a priority. That was 20K miles ago, best PM yet.

This has been debated here ad nauseam. Bottom line is that Toyota's definition of "lifetime" is 100,000 miles because that's when their responsibility for the drivetrain ends. Our definition is the real meaning of "lifetime" - until the truck falls apart to the extent it can't be driven anymore.
Think about what's going on inside your transmission. No fluid, regardless of what it's made of, is going to last 20 years and 500K miles, which is easily the "lifetime" of some 4Runners. Plus there's nothing to indicate WS fluid is fundamentally different than any other transmission fluid.
For an unbiased 3rd party opinion, I recommend the always entertaining Scotty Kilmer's take.
If you do change it out, get a full exchange but not a pressurized flush. The pressurized type is what can dislodge stuff you don't want floating around in there.

Appreciate the responses. At the dealer now.
He found that spark plugs were done 126k so not needed however serpentine belt was not done at 90k so we are doing that, power steering and brake flush, and complete inspection. Will probably do brakes next visit and as the Toyota brake special is essentially worthless pads AND calipers will need to be done. Wish I had a great brake shop here in the PNW.
Will ask him about the tranny exchange.

Hello Alaskaman, I just wanted to chime in and state that for severe use Toyota recommends 60k on the driveline fluids (tranny, diffs, t-case). A lot of the users here would agree that is a safe interval if you are offroading or towing. I have a thread here that discusses tranny oil lab analysis, among others that would pop up in a search. I would ad that you should get your drive shaft greased and torqued, an often forgotten part of regular service.
other questions that come to mind:
Last time you had an alignment and tire rotations?
Battery age and discharge test?
Cheers,
Tim

Thanks Tim. Diff and transfer at 94k, will most likely do transmission when I do brakes next visit. Alignment done 140K and need to rotate and will ask about the grease on the drive shaft. I think that is part of the 150k service but will check. New battery in the last year.

Brake flush gave more push to the brake pressure brakes are at 7 front and 4 rear. They suggested doing the radiator hoses upper and lower a little soft but not urgent (quoted $600.00) which is very high but I don't work on cars I repair people...
He liked the Beast. The Beast liked him...

Called around replacement upper and lower with new anti freeze is $289.00 . He must have been confused.

That is crazy high. The radiator swap is quite simple. I think they are charging at least double what it should be.
