A dynamic radial shaft seal assembly (10) includes an inner wear sleeve (16) having a cylindrical inner wall (18) with a bore sized for receipt about a shaft and an outer running surface (24). The inner wear sleeve (16) has a flange (26) extending radially outwardly from the running surface (24). The assembly further includes an outer case (28) having cylindrical outer wall (30) configured for receipt in a housing and a rim (36) extending radially inwardly from the outer wall (30). An elastomeric body (38) is attached to the rim (36) The elastomeric body (38) includes a main seal lip (40) configured to engage the outer running surface (24) of the inner wear sleeve (16) and a plurality of thrust pads (42) extending axially from the rim (36) for engagement with the flange (26). The thrust pads (42) are spaced circumferentially from one another by gaps (44). The elastomeric body (38) further includes a first dust exclusion lip (46) extending axially from the rim (36) and bridging the gaps (44) between the thrust pads (42).
