when traveling about 35 to 40 mph..if i hit a bump or uneven surface.i recieve a floating or play in my steering..it continues until i break or slow down..it seems like a caliper or something is loose..just over 100,000 miles.

have the front suspension checked. it sounds like you have some worn out parts.
Agree with Roy, also check the steering damper!
