Differential Fluid Change DIY Guide (Front & Rear Diff) - for 2025+ 4Runner 6th gen

Very detailed procedure, thank you. I wonder what a dealer would charge to change front and rear? I am getting to the point of not wanting to do my own vehicle maintenance

I asked my dealership here in Florida yesterday. It was $199 per differential. They also said they use 75w90 , so we know it isn’t Toyota branded.

great write up!

It's strange that Amsoil's website doesn't list any fluids for the Transfer Case and Differential.

Anyone ever check the levels when you first get the vehicle? This is my 4th 4Runner and I always make it a habit to double check the diff's and transfer case. Just got done and the rear was pretty light I think I put about a 1/3rd of a quart in, front was a little better. Transfer case was almost up the top but still took a pretty good pump to get it to the fill plug. I used Redline 75/85 for the diffs and MT-LV for the transfer case. I'll double check the trans fluid probably on the weekend if my OBDII reader will pick up the temp. I only use factory WS for that one. Not that I don't trust Toyota, but I don't trust anyone.
