Re: Black differential fluid

[Bush4brits@aol.com]

Mike,
I know it's one of the most overlooked maintenance items, but I change my
differential fluid every 2 or 3 years.
Like any lubricating fluid, it is subjected to heat and stress under load and
will eventually break down. 
Look for metal chips while you've got you're fingers in the oil........that
should tell you something about the condition of the diff.
