A slack adjuster assembly (280) for heavy-duty vehicles, the slack adjuster assembly (280) comprising a slack adjuster (282) and an inboard sealing assembly (380). The slack adjuster (282) is disposed about and has an internal spline (302) for receiving an external spline (288) of an inboard end (284) of a camshaft (286) of a camshaft assembly of the heavy-duty vehicle. The internal spline (302) has a radial clearance (R) from the external spline (288). The inboard sealing assembly (380) includes mechanical components that cooperate with the radial clearance (R) to increase grease flow and distribution. The inboard sealing assembly (380) is disposed over the inboard end (284) of the camshaft (286) and engages an inboard side of the slack adjuster (282) to form a 360-degree seal about the inboard side.
