!!!READ THIS CAREFULLY!!!! You can NOT "check" U joints by looking, by shaking, or by guessing. There is ONLY ONE WAY. That is to REMOVE the shaft. You remove the two rear caps and inspect, and you move the rear joint through it's movement, feeling for "dryness" and roughness in the needles
You take the yoke in hand and move both sets of caps the same way. You will feel looseness, "over" tightness" caused by dry needles, and so on.............
