If the doughnut mounting holes have worn in an eccentic pattern with elongated holes, then at lower speeds or when the propshaft is unloaded, it can reciprocate around the logitudinal axis causing the side-to-side "feeling". At higher speeds or under load, the spinning smooths the imbalance gyroscopically. The only real way of telling is disassembly.
