Nicklaus had hip trouble fairly early in his career, starting with bursitis in his left hip. During the late 1960s, he deemphasized his legendary fade preference in favor of the draw - the draw caused less stress on his hip. (See Golf My Way, 1974, p. 30).
Also in the book, Nicklaus emphasized that the hips needed to turn/rotate during the backswing. The book even shows a series of full-page pictures of different points of his swing - if you flip through the pages, you get a slow-motion rendering of his swing.
Palmer also had hip trouble. A scattering of golf stories circa 2000 talk about Palmer and Nicklaus either entering or skipping a Champions Tour event depending on their hip status.
As for Player, he had back trouble later in his career. For many years, he has promoted the draw as the standard shot - in part, because he says it's less stressful on the back than a fade. I saw an early "draw" article he did when I was age 40, and having a bit of back trouble myself.
As far as X Factor problems, Cigar Aficionado magazine had an article on tour golf pro injuries in its early summer issue. The author talked to physiologists and physical therapy people about the injury pathologies of golfers who use the modern golf swing with minimal hip action on the backswing.
