CHEVROLET ASTRO BUMP PROBLEM

2005 Chevrolet Astro • 142,000 miles

My Chevy Astro Van seemed to 'buck' as I was driving 40mph. I thought maybe it was just a large bump on the road, until it happened 3 more times (60mph). Luckily I was only 8 miles from home and arrived safely. Any suggestions on what is happening? I am afraid to drive it to the mechanic.
