Since everyone's hanging in for the next exciting detail of my saga... Diagnosis: A bad U-joint. Will have part tomorrow and will replace then. Don't think he (Asst Mgr) said which one (and what do I know--my only image of d-shaft/u-joint is from long ago: one-piece, with I thought ONE u-joint). He did confirm my truck has 2-piece drive shaft. Work is under warranty. He said first we need to take care of this and see what truck is like with new u-joint. I buy that, and said so. Still, I inserted question: did guy check shaft angle? No. But I think that was likely pointless since he'll be disconnecting it... Insofar as I understand these things. Sorry I ramble. First visit to ANY dealership since 7/2015, when this one became dead to me. Still recovering from this AM. >>Not that I'm cynical... but might any of you advise that i take pics of joint/s now... to be sure that one actually gets changed? I've seen pics of modern u-joints, but not entirely sure of what I'm looking for under this (2wd) animal. (This would make sense if you really knew me: I've seen a fair amount of the underbelly when changing rear wheels twice a year. Never noticed much more than the axle and wheels. That's like going to college and graduating with the ability to pronounce my name correctly.) >>And after changing a u-joint, wouldn't the tech check shaft to make sure it's level? Going back early AM (EST) Would hugely appreciate it if any of you has a minute to set me straight on those >>2 questions. Thank you!
