This morning, the Rubi suddenly developed a knocking vibration. Thought it was a flat tire. It is something rotating causing the vibration. When I applied the brakes, tho' to slow down and pull over, the knocking vibe stopped went away. The knocking started and sounded just like a rock in the tire tread. But then increased. Tires were fine. Suspension pieces all seemed in place and tight. Got back in and drove ahead slowly and got the knocking again, increased as I went faster. But when I turn very sharply to the right, no knocking. Very sharply to the left, no knocking. Just driving straight ahead.
Feels like its coming from the rear end, but can't be sure. I have a 4" lift with the transfer case lowered to reduce driveshaft angles. Has run butter smooth without any vibes at all. Until now. Got about 54K miles. Went into and out of 4WD ok, didn't seem to affect anything with the knocking.
Bad U-joint here?? Something is amiss with a rotating part. ANY ADVICE GREATLY APPRECIATED
