Maintenance parts washers etc

I'm having a hard time finding all the gaskets/crush washers for maint on toyota website for our 2021 4 runner 4x4.
I want to stock up on oil pan gaskets, rear and front diff drain and refill gaskets, transfer case drain and refill and transmission drain and refill gaskets.
I found generic ones on Amazon that may be all the correct ones but unsure if I would have leaks.
Do most you run the cheap toyota oil filters ?
For power steering Dex 111 is obsolete replaced with Dex v1 what to use ?

 

Why not just go to your local auto parts store and get?

I agree with OEM for most parts but washers I don't. I just go to my O Riley and buy a 10 pack.

Dex/Merc , Dex IV, Dex V
But if you need to carry fluid you got a leak somewhere.

 

No leak, I like to exchange a certain amount of fluid by sucking some out with a turkey baster and refilling with some new stuff every so often

 

There is regular maintenance and overkill. But up to you.

 

Sure, Toyota engineers recommends to run the cheapest oil filter you can find, sometimes they recommend not running any just so you can destroy your engine even faster.
Read it it's in your manual!

I responded this way because you are obviously joking......RIGHT?

 

umm, how do you “suck” fluid out of any of the things you mentioned with a turkey bastet?

 

You suck it out of the power steering reservoir and replace with new which is completely over kill to do on a normal basis. Kinda like doing the same with brake fluid and coolant. Just wait til its time and flush the whole damn thing.

Some that don't flush the whole system will do it this way. Suck some out replace with fresh fluid. Turn the wheel a bunch of times and repeat.

 

I bought a syringe to do just this lol. Still havent done it yet, but soon. Bleeding out brakes is a messy pain in the ass, and it seems to carry some risk of causing problems if you screw it up and suck air. And lately, it seems like I’m prone to screw things up a bit more than back in the day. Seems like a convenient way to at least keep the water content of brake fluid under control.

Regarding washers, I’m incredibly lazy on that particular item, mostly because I’ve gotten away with using the same washers for oil changes since forever. I’ve never gotten a leak, ever. Drained the diffs and TC about a month ago, used the same washers. No leaks either. I’m not too hard on them since I’m easy on the torque, and because I sort of lap the washers onto the surface every time, just to make sure I get a good seal.

 

I’ve done this with the power steering pump and brake reservoir and on vehicles.

 

T4R5th-4WD use hydraulic brake booster pump, not vacuum, like most and like T4R5th-2WD. every time engine started, pump building pressure in a system. if pressure achieved in a system - no red light on dash. if leak - pump will run continually until all liquid are gone. this is how brake bleeding done. most "screw it up and suck air" happened when bleeding screw unscrewed and air seeps in along threads. new bleeders screws have some kind of thread sealer from factory, that work only once. but Toyota's pink grease for caliper pistons (every 50k miles, in a rust belt or off road every 30k miles) works ok for that and do not contaminate liquid, as it is soap based, not petroleum based.
and it is not smart to use non-Toyota OEM maintenance liquids and parts.

 

and your transfer case? Your diff cases?

 

No, I completely drain and fill the gear boxes with new oil.
