A tractor or trailer axle replacement spindle and seal ring assembly includes a spindle with an elongate cylindrical body having bearing surfaces and threads. The seal ring is a shorter annular component having a circular opening sized to achieve an interference fit with the spindle. A portion of the exterior surface of the spindle and the interior surface of the ring seal includes complementary regions having a small, constant and equal taper. Preferably, at each end of the tapered regions of the spindle and the seal ring resides an annulus or cylindrical region of constant diameter. The spindle may also include a shoulder or flange at or adjacent its end opposite the threads which positively axially locates the seal ring thereon. When the two components are to be assembled, the seal ring is heated to several hundred degrees Fahrenheit and slid onto the spindle until the complementary tapered regions align.
