1998 Dodge Caravan Ticking noise that became louder

Noises problem
1998 Dodge Caravan Front Wheel Drive Automatic 120000 miles

Yesterday I was driving home, about 150 miles, when with about 50 miles to go, I noticed a ticking noise coming from the front left of the vehicle. Having just replaced a flat a few weeks ago, I stopped to make sure the lugs were tight, which they were, and continued on my way. Eventually, the ticking got louder and louder, turning into a popping noise whose frequency kept up with my speed. By the time I got home, the popping got so loud that the entire van started to shake. However, the noise would go away when stepping on the accelerator. It wouldn't go away until I came to a complete stop, and would start back up again when I reached 25-30 mph. After doing some research, I'm most likely sure it is a problem with a CV joint, although when I turned, the noise didn't get any worse or better.
