Other than the obvious sheetmetal and interior differences, what all was changed on the 08 redesign? I mean, is it an all new frame, is the structural stuff under the skin new also?

 

Motor went to a twin sequential turbo setup. I think the front axle changed again. And the frame may have become a little more boxed?

Other than that really can't help ya. Had a DVD talking about all the changed but haven't seen it for awhile.

 

longer leaf springs in the rear,

 

What changed on/in/around it?

 

The 08s use the 'Quiet Steel' in the cab construction. I know my 08 is worlds better than the 04 it replaced, in my opinion.

 

08 got the better mirrors as well and the grill comes up with the hood

 

Something in my head keeps sayin they switched to CV shafts... but that just doesn't make sense...

 

I recall there was more changes than a person could list. One of the guys on the forum from Ford said even though they look more or less the same the 08 was close to a complete redesign not just a facelift. It has hundreds of new parts.

 

Why would you need a constant velocity joint in a solid front axle?

 

they last longer and deal with extreme tight turns better..

same reason why a CV joint on drive shafts are the ultimate upgrade for ur driveline..

 

So is there a CV joint behind the knuckle or not? Someone who actually owns an 08 should go look.
