30k recommended service

Taking my 2021 SR5 4WD in for 30k service in the morning. What can I do myself or bypass? I'm not the most mechanically inclined. I don't tow or have heavy loads and I don't drive dirt or dusty roads. Here are the ones I need help with if I should let the dealership do them or not.
-Preform fuel injection service
-Replace brake fluid
-Replace front differential fluid
-Replace rear differential fluid (including limited slip)
-Replace transfer case oil

 

1: pour bottle seafoam in gas tank
2: suck the brake fluid from master reservoir and pour some new brake fluid in
3:&4: buy some

$39 75w-90 GL-5 Limited Slip, Ultra Long Drain 500k Miles, Manual Transmission, Gear/Differential Lubricant (1 Gallon)

75w-90 and change those diff, it's only drain and fill
5: buy transfer case oil, same drain and fill

 

Fuel injection service is a scam(if it’s running fine, don’t mess with it)
The rest is pretty easy, tons of content on YouTube

 

The basic 30k service per the maintenance manual is just oil/filter, tire rotation, air filter and cabin filter. You could certainly do the filters using OEM parts and save the money on labor.

The keeping truck forever 30k service would be the above plus front/rear differential fluid, transfer case fluid, trans fluid drain/fill, brake fluid, lubricate brake pins/slides.

 

don't know what diff fluid dealer use, but if you get some synthetic diff fluid you could see mpg gain.

 

I ended up letting the dealership do all the service besides the fuel injection service. I plan on keeping the truck forever. Please provide more details for how I complete the fuel injection service on my own or direct me to some videos if that service is necessary. I don't know if it's coincidence but I normally get 13.9-14.0 mpg but after the service I am getting 15.5 mpg.

Thanks for all the feedback!

 

some ppl gain mpg after diff fluid change, don't know why.

 

Heres a demonstration how the dealer is supposed to clean the injectors

 

If you don’t mind…how much did your dealer charge?

 

~$576

 

So if they do it that way it's worth the money?

 

I add Amsoil P.I. to the gas tank every oil change and do some full throttle fun intermittently through that tank of gas.....fuel injection treatment complete.

 

U don't need the so called fuel injection service, ever. Just gun it on a freeway on ramp once a month to clean the carbon on your valves.

I'll be doing 30k maintenance with a tranny drain and fill as well.

 

The injector cleaning seems questionable.

Id think a fuel filter is more important
