I still haven't done this to my GS4...I need to get off my A**. How long between changes? If I had problems, how would I know? All seems ok now.

I think I saw BananaGS has DIY help.

 

The fluid from my stock differential, with 65,000 miles on the clock, was pristine. Like new. The previous owner was a middle-aged Japanese couple. I'm fairly certain they never had the rear end fluid changed.

This ain't your father's Chevrolet...
