Re fused joint , an old trick I was taught years ago . Get a decent size lump of metal , some thing like a club hammer head pressed to one side of the eye. Give a good hard tap with a decent size hammer to the opposite side of the eye. If you catch it right the tiny vibration you set up will release the taper. If the ball joints are sound but the rubber boot is shot then you can also get the seals as a separate item on eBay [-/
