My standard 1998 Subaru Legacy Outback just started shuddering between 40-50 mpr on 1998 Subaru Legacy Outback

It shudders and make a knock sound by steering wheel. This lasts for 1-2 minutes then drives fine like nothing happened. Any ideas of what might be causing this?

Check the steering linkage and the tires.
