Vibration from front wheel that comes & goes--'92 Corolla

1992 Toyota Corolla wagon:

Intense vibration like wheel is a rubber ball bouncing on the road, feels like coming from front passenger wheel. Manual transmission.



Starts at about 30mph–but it doesn’t always happen. On some drives get no vibration, & sometimes slight vibration. Seems to be associated with acceleration as it lessons/goes away when ease off gas (but comes right back).–mechanic said bearings are fine. Any ideas on what to have inspected?

Everything in the front end; tires, shocks/struts, steering, suspension, CV joints.
