Boppa's old yeller truck

I'm not a professional or qualified shade tree mechanic but, I was having the same issues with my 67 gmc when I lowered it 4/6.

Yoke has proper clearance, about 5/8 back from bottomed. Angle is getting rechecked this weekend. No clunk. We pulled the shaft and shut the motor off and pulled it 65 mph on a strap, still throb. Been on the horn with Oreilly about swapping us out for new. Well see.
