After starting out going five or six miles the rear end starts making a noise and starts vibrating then gets worse like thumping. If I stop at a stop sign and start up again it goes away, but comes back. I replaced the rear driveshaft with a new one.

You will have to check that you do not have a tire out of round, a buckled rim, all rear suspension components are tight and the replaced drive shaft is installed correctly. I would be leaning towards a tire as sometimes as they heat up they can deform and cause a thumping noise.

Rotated tires and still vibrating. Checked driveshaft, it is okay.

Check for worn rear suspension components and check rear tail shaft and differential support bushes, if all looks good get a four wheel alignment.
