on our 1995 c220 we were just informed that the rear differential is leaking and would need to be repaired in the next 6 months or so for about 700. Does that seem correct? Are there lesser expensive ways around this? There are no current drivability issues

Thanks for helping.

 

sounds about right.. All depends on whats leaking on the rear diff.. Pinion seal, side seals and/or rear cover seal... They usually remove the rear diff. from the car to reseal it...
