1990 Toyota Corolla Question: passenger wheel locks up

Was going up north to make a visit.Suddenly a clanking went in the front end and the wheels would lock up. I bought and replaced a new cv half shaft wheel bearing and wheel seal for the driver side.took it for a test drive made it about 15 feet then the passenger side did it. had a guy come look and he said the axle that connects to the transmission is wobbely and loose.. any suggestions before i go buy alot more partsw
