im gonna change the differential oil in my car is it difficult to do that

 

Nope. Just remove the diff cover and old fluid will run out. (warning it stinks) Then clean the gasket surfaces, replace the diff cover with new gasket or RTV. Next, remove the fill plug and fill until the oil come back out. Finally, replace the fill plug.

 

thanks mdenz3

 

I dont think it stinks

 

well don't drink it if it smells good to you. Prob. lose about 10 pounds of crap.
