Hi,
Here is a good page on the actual movement of the axis. It claimsthat the center of the Chandler Wobble is drifting. From what I can gather, it is a matter of a few meters.

The Earth's axis of rotation – and hence the position of the North Pole – was commonly believed to be fixed until, in the 18th century, the mathematician Leonhard Euler predicted that the axis might "wobble" slightly. Around the beginning of the 20th century astronomers noticed a small apparent "variation of latitude", as determined for a fixed point on Earth from the observation of stars. Part of this variation could be attributed to a wandering of the Pole, by a range of a few meters. The wandering has several periodic components and an irregular component. The component with a period of about 435 days is identified with the 8 month wandering predicted by Euler and is now called the Chandler wobble after its discoverer. This "wobble" means that a definition of the Pole based on the axis of rotation is not useful when more than about 1'' precision is required.
