30k Maintenance

Gonna be coming up on the 30k maintenance here within the next couple of months and figured I would start buying everything I needed now since the 75w Toyota transfer case oil is so damn expensive as well the toyota 75w-85 diff fluid. Since I need 2 L of the transfer case oil and 7 L of the diff fluid.

Do I need anything else to get the job done, gaskets/crush washers etc?
I know i'm gonna need to buy some type of pump for the refill.

I see that the blauparts has ravenol for seriously a fraction of the price of the OEM fluids. In my cart right now the total is $145 for the 2 L of trasfer case fluid and 7 L of diff fluid and when looking at OEM fluids almost $300. Is this stuff just garbage or is the OEM fluid severely overpriced? And if anyone has used both is there a noticeable difference in fluid longevity and/or performance?

 

OEM is much more than non-OEM. I used Redline in the rear and front differentials. Ravenol in the transfer case.

 

you need the crush washer kits

 

No need to change t-case fluid at 30k IMO. I’m waiting for 75k. As mentioned, you’ll need washers for the drain and fill bolts for both diffs. 3 of the 4 are the same - one on the front is copper.

 

Did my first front and rear diff's fluid change last weekend at 48,500 miles. I used RedLine 75w-85 fluid, got it of Amazon along with the crush washer kit. Both fluids were still very clean and found very little metal shavings on the magnets. I'm not gonna touch the transfer case till 70 or so thousand miles. Needed a 24mm socket for the rear diff and I believe a 10mm allen socket for front diff plugs.
