much appreciated!

Another vote for Redline MT90, it just works. I'm sure any gear oil of correct viscosity would work. GL4 is better for transmissions (supposedly).

I put GL5 in my transfer case and had no problems. If you do all the diffs and TC fluids at once, get the giant bottle of gear oil. For the differential get the cheapest GL5 oil, it makes no difference.

One of the first things I did when I bought my '98 was change the diffs/trans fluid. I put Redline MT-90 in, and I did find shifting was a bit easier/less clunky but this is hardly scientific. I had only driven the thing for a few weeks before I changed it out. I would definitely be interested in seeing some sort of comparison, but that hard to come by.

To the OP, 4runner.org has gone up and down like a yo-yo over the past few years. I assume it's cause people like me read the site and don't donate to the hosting costs... But after the first time I noticed it went down I ripped the entire site. I attached a PDF print out of the write up your looking for.

Made a profile specifically to say thank you for this! This was exactly what I was looking for. I was terrified that I was going to ruin my car but I'm feeling much better about going into this project now. Thank you!
