The differential on your Mercedes-Benz is filled with gear lubricant in order to keep all of the gears and bearings working properly and to keep the differential quiet and cool. This gear lubricant is kept inside of the differential by seals.
One such seal is the differential pinion seal. This seal is pressed into the differential housing around the pinion gear input shaft bore, and prevents gear lubricant from leaking out around the input shaft. Over the years however, this seal is know to become brittle, shrink and start leaking fluid from the differential.
If you have noticed drips of oil on your garage floor from the rear of your car, your differential pinion seal may be to blame. If so, replace it today with a quality part from ECS Tuning, and while you are there, now is a great time to change the gear lubricant inside of the differential. ECS Tuning carries a full line of gear lubricant for your Mercedes-Benz so that you can keep it on the road, performing well for years to come.
