4runner transfer case. A topic beaten to death. I just need to know one thing

[RodneyM]

Does the transfer case on the 5th gen 4runner contain any brass, copper or soft metals? I know many people are using gl-5 in theirs and I would like to do the same but I’ve been obsessed with the idea of gl5 eating up the soft metals.

Obsess owner what the owners manual recommended specs are.

2019 Tacoma drained the factory 75w out about a week after it was new

Lucas 75w90 changed it again at 50k with same was as clean as new and zero metals visual

Now at 91k no issues ever freezing cold or blistering hot with a few Colorado off road mountain passes in 4 wheel

As for soft metals I do believe there is a internal part or two that are "soft" metal

Toyota 75w works for many.

I've had Supertech Synthetic 75w90(changed twice) in mine for about 150k. No issues.

Cool. Thanks for the reply, man. Another good mark for gl-5. Anyone else?

I got HPL to make me some 75w for my tundra. You could reach out to Dave and he can hook you up.
