Only one way to find out. Take the old girl out for a spin. Let me know how you get on.

Take the disco for a spin, get some speed up & get it all up to temp. When you get back, touch each individual wheel hub for any signs of excessive heat displacement. They should be cool to the touch. If you can't keep your fingers on the hub from excessive heat, then there's your problem. (Probably bearing)
