Now to some details
1. Brake fluid looks good. And tester doesn't show any moisture. So, no brake bleeding for now.
2. Transfer case fluid - used e$$$pensive Toyota fluid, got it on sale. I feel like it was needed. Was dark-ish. I want to shake hand to the guy who designed protection contraption, 13 bolts???!! LOL
3. Rear diff fluid - actually looked good. There was amount of metal dust on plug, but nothing bad considering it's from new. So that one - I'd say it can go longer.
4. Front diff fluid - Don't know. It looked worn. Not whole lot of shavings, but replacement was needed. Also, I felt like it was different viscosity from rear. I used same M1 75W-90 on both front/rear so I am not sure about this...
5. Engine oil - switched to regular Toyota filters. I change oil every 5-6k so it will be totally fine. I still have 2 new TRD filters, but after seeing they are NLA and like $90 on
eBay I didn't feel like using them. Might just sell it for profit

6. Lubed driveshaft (one). And then my stupid grease gun quit. And it's messy. Any suggestion on "buy once cry once" grease gun?. Also, I am used to 100 series where you just take it off parking and can rotate by driveshaft to get to zirks. Here I had to take off electronic parking (pain). Then Put in neutral. And then listen to all this beeping while I was trying to get under.
