I am not sure whats going on or it could be just be me, but virtually every time I shift I feel a thud in the back, is this the two piece drive shaft kicking around?

If it is, is there anyway to solve it besides switching over to a solid drive shaft?

Please let me know - thanks!

 

Please anyone?

 

Mine does it too, sometimes. I think as the two piece driveshaft gets some miles on it, it loosens up and starts making a little noise. If it's real pronounced you might want to drop it and check the u joints. I looked at them and they look like they have to be machined in...thanks Ford

 

I have around 1500 mi though :/ so I dunno

 

Smooth J,

I have the same problem on my V6. I an going to get an aluminum shaft before summer. to me this is just poor design on Ford's part.

 

Time for a 1 piece driveline...AND DONT CHEAP OUT ON IT!!
I put a Dynotech 3.5 aluminum on (from Brenspeed)I cant even begin to describe how much better it is then the stock 2 piece boat anchor!!

 

Hmm, don't I have to worry about vibrations and etc though?

 

yup probably the two piece thunk

 

I discussed the issue in depth with Seth at Brenspeed. The vibration problems are ALWAYS with the less expensive drivelines. They have never had a problem with any Dynotech, (rated to 900 HP) No screwing around with installation, direct bolt on. I could not be happier, as I said it made my car TOTALLY different, smooth,tight, positive shifts. (manual trans.)

 

Are you talking about this one?:

Also, is a loop required or no?
