Q: I was just told my rear differential pinion seal was leaking when I got an oil change.

asked by on August 13, 2016

Is this something that requires immediate attention? I just had the whole real differential replaced a year ago. What needs to actually be done to fix this? There is nothing noticeable when it's driving. How long can it be driven like this.

My car has 185000 miles.
My car has an automatic transmission.
