Look if you want to believe what a Ford engineer tells you go right ahead. You can live your life from internet experiences all you want. I prefer to use real experience. You show your ignorance when you say foolish stuff like "You haven't done any of that. Your 1 piece is not part of that system. You just went to the store, bought something, and bolted it in. And now are going crazy because engineer's countered your false story about the 2 piece being faulty." First it just shows you know nothing about how these drive shafts are manufactured, measured or tested. Since you love to believe everything you read off the net educate yourself by visiting a couple of these drive shafts companies websites and actually do some research not just regurgitate things you read that support your opinion. it is called being objective. Second I said my drive shaft went bad at the bearing in 08' after 38K miles of easy driving. When the dealer wanted to replace it for $1200 I looked into it and found out about the one piece units. Now not all are created equal but there are some VERY high quality units out there that have taken what Ford originally did and improved upon it with lighter weight, better materials and smoother operation. Which in turn resulted in quicker acceleration and reduced weight. Since 2008 I have not had one single issue with my drive shaft. So let us count 2008 to 2013 is 5 years and 62K trouble free miles. That means it has lasted LONGER and served my purposes BETTER then the OE unit did. Now the clunk you refuse to acknowledge and keep saying it isn't the 2 piece shaft causing is in MANY of these cars. Most if not all report reduced or ELIMINATED clunking noise when they go from the OE unit to one of the high quality 1 piece units. So how does this happen if the 2 piece DOESN'T PLAY SOME ROLE IN THIS AND IF THE ONLY CHANGE THE OWNERS MAKE IS THE DRIVE SHAFT? We all can't be telling the same lie. Not to mention you still haven't answered my question as to have you ever actually compared the two and tried one for yourself or are just repeating what someone else said? You are like that state farm commercial where that young lady believes everything she has seen on the internet. Enjoy your french model sir.
