Check your u joints first.

I'd get under and with flashlight, all u joints , inspect, touch , wiggle, how much movement? Include the rear diff pinion slack, play also .

I checked all my ujoints all the way back and I tried to move and wiggle them but everything was tight

You can continue with the same thread, posting. Multiple postings on same issue are not cool.
And front shaft and both half shafts? Does vibration follow eng RPM or does it increase with decrease with wheel speed? Vibration in steering wheel, or seat of pants thing? Two different animals. Check front wheels bearings? Front suspension?

If you aren't removing the caps, you're not REALLY checking them. Of course, nobody removes caps to check joints except for those caps that slide off when the driveshaft is removed from the vehicle. Point is, even the minimal extra labor to remove the shaft--while helpful--doesn't guarantee that the joints can be properly inspected.

Trying to verify the condition of U-joints without removing the driveshaft is hopeless. Unless the joints are ready to break, you're not likely to find problems with them.

Yup. I've had more u-joints fail by tightening up and getting notchy than loosening up. Just yesterday my wife's Chrysler started humming at speed on the throttle, and I'm pretty sure when I take the driveshaft loose I'm going to have a stiff u-joint.

This is quite helpful. And here I thought I‘d checked mine. Evidently not.

Since reading the above, and two days after my starter unexpectedly went kaput, I’ve been thinking about U-joints in a ‘wondering what else is lurking, ready to break‘ kind of way.

I’ll not be towing any more until April. Properly inspecting the U-joints is now on the list for this winter.
