1987 Ranger 4x4 clutch problems

[Supercrewzer76]

I have a 1987 Ford Ranger 4x4. I am having clutch issues. I have not owned it long the old man I bought it from said the clutch had been replaced. He had stopped driving it due to wiring issues. I was wondering if the pilot bearing is sticking from setting to much. When driving it sometimes slips and also will sometimes not engage at all. Any quick fixes or I am going to have to drop the trans and replace the clutch or pilot bearing
