That sucks about your eye. I wear sunglasses almost all the time but under the car I didn't , so i could see better. When I was younger I'd do most anything without eye protection. Now that I'm getting older.... For some reason I think about those things.
I was told by a knowledgeable guy, and followed it up with some reading, that redline is far superior gear oil than most. Just like royal purple is for motor oil.
I did all my stuff in redline and it was cheaper. I couldnt believe how much that RP was.
I wish I would have gotten the high temp DT4 for the transfer case, but I just grabbed the regular.
