Just traded in my `04 5.4 XLT for an `07 4.6 XLT and decided to take a peek under the truck. I was only partly surprised to see that Ford had switched to aluminum, and is now a 1 piece design instead of a 2 piece with a center bearing. At least I assume it`s aluminum - either that or I got the only Ford driveshaft with not a spot of rust. (actually took a magnet to it to check)

Anyone else out there with an `07 notice this?

BTW, the throttle response of my new `07 is better than my `04. It's especially noticeable from a start. In general the throttle lag seems greatly reduced.

no but i hope to tell you soon when i get rid of my 04 150 5.4 and get my new xlt 150 5.4, i will let ya know. Im hoping their gonna up the 07 rebate, hehehe

 

can you post pics?

 

I'll try to take some tomorrow, but may not be able to. The truck goes back to the dealer for a Katzkinz leather interior.

BTW, both trucks were/are supercrews.

 

Thats pretty cool when i test drove a 06 Supercab XLT 5.4 3.55LS gears i was impressed it was real preppy didnt even have to push down that much and you where gone good power also noticed the exhaust was really pretty throaty too i liked it all truck manufacturs these days are going with stainless steel exhaust systems...

I figured it probably had been covered ... wanted to post just in case.

I too am more impressed with the 4.6's exhaust note on my `07. The `04 5.4 was quieter, but wimpy sounding. The `07 has a nice growl to it.

 

this is a clip of the factory exhaust on my '05 4.6L...
