Wobble in the steering

When my steering shaft, from the firewall to the steering box was going bad, it would get jumpy, or a jumpy feeling in the steering/front end when I would hit bumps at certain speeds. The steering shaft itself looked fine, it did not have any excessive play or visually bad u-joints. I replaced that shaft and that occasional front end issue went away. Is it the original shaft on there? They are only good for so many miles and do need to be replaced. With an 871, and if the original shaft, it is probably time to replace anyways.
