i recently changed my front and rrear diff. fluids. my when i asked my dealer how much to add he told me to fill until full. now i am leaking differential fluid. between the two of them they took almost a full quart. did i overfill them. i don't have an owners manual, how much does it say to put in. should i worry about the leaking or will it stop leaking when the excess fluid is all out, or will it continue to leak until empty. got a trip planned this weekend so i have to figure something out. any help would be appreciated.

 

Yes you did over fill them. Fill them to 1 inch BELOW the fill plug. bend a wire at a 90, with one leg exactly 1" long as you fill the diff check the level until the wire with the 1" leg touches the oil.

 

yort is correct.
