Rear Differential

[ricklee4570]

How often does Ford reccomend changing the rear differential fluid?

I have a 1994 model.

Thanks!

Every 75-100 K should be good. I can't remember what they recommend though.

For my 1993, 100K is the recomendation per Owner's Manual. Be sure to add the Friction Modifier if you have a limited slip differential.
