I will go with the ujoints, if the needle bearings have worked there way out or even partialy out of the housing it will sound exactly like you are discribing. You can easily do them yourself, you just need to melt the plastic injected retainers first, you will need a little propane torch to get them hot enough. Also make sure you raise the rear end to keep any fluid in the transmission were it belongs when you take the driveshaft out.
