Yes, but since the inner tie rod ends are inside the boots and ship as part of the rack, he's likely referring to the rack and inner rod ends as a unit. Of course, they're replaceable independently from the rest of the rack. The innards of the rack are a gear that meshes with a toothed rod and both are immersed in power steering fluid, so it's very unlikely for play to develop internally. The failure modes are usually leaky seals, a loose tie rod end ball/socket, torn dust boot, or loose/worn rack mount bushings, but not the geared parts.
So, if it were my rig, I would want to know exactly what's loose because it's a lot easier to replace a worn tie rod end than the rack.
