A seal assembly includes a first member and a second member. The first member defines a first central passage, and the second member defines a second central passage, both of which extend along a central axis. An input shaft of a steering gear extends through the first and second central passages. The second member is attached to the input shaft, and is rotatable with the input shaft about the central axis relative to the first member. An outer seal is disposed between and in sealing engagement with the first member and the second member. An inner seal is supported by and moveable with the second member. The inner seal is disposed in sealing engagement with second member and the input shaft of the steering gear. The second member is PTFE fiber filled acetal, and the outer seal is glass filled PTFE to reduce noise generated by relative movement therebetween.
