GM Front Drive Axle Inner Shaft Seal, Duramax | 2011 - 2019

The genuine GM 23196678 front drive axle inner shaft seal seals the front differential where the inner axle shaft exits the carrier on 2011-2019 Chevrolet Silverado and GMC Sierra 2500HD and 3500HD 4WD trucks. A worn seal lets gear oil seep out at the axle tube or the disconnect housing, which leaves the differential low on fluid and puts the bearings and gears at risk. This is the factory GM seal, and it replaces earlier part numbers 22935647 and 20768559.

Benefits

Using the factory seal gives you the original lip design and fit, so it seals right the first time and keeps gear oil where it belongs. It is worth replacing whenever the axle shaft or the Front Axle Actuator is out of the truck. If you are servicing the rear axle too, see our ACDelco Rear Axle Seal. For 2001-2010 trucks, use the 2001-2010 Front Drive Axle Inner Shaft Seal.
