I changed the rear differential fluid in my 2005 E450 cutaway chassis motorhome with a Dana 80HD rear using fords 75w-140 fluid and added the required amount of friction modifier. However, I was wrong about having a limited slip differential. Will the addition of the friction modifier in a non limited slip differential have any negative consequence? Thanks in advance for your responses.

 

No it won't.

 

Nope, won't do a thing.
