2nd Gen Non-Engine/Transmission Any major differences between 2001.5 and 2003 CTD?

[DaveN]

I was able to pick up a 2003 manual CHEAP, but I have a 2001. 5 - are there any major drivetrain or engine changes from 2001 to 2003? I'm thinking no, but.....

 

[Joseph Donnelly]

Yes. Virtually everything is different--frame, body, differentials, brakes, fuel injection system, etc.

What Joe said. But the bottom line is that you would have to have one AMAZING deal in order to be better off with the '03.



Brakes: '03 is much larger and more powerful. This is why they now have 17" wheels.



Frame: "03 is made of thinner metal, but hydroformed to be stronger. It relies more on shape and design for strength. It is stiffer than the '01.



Injection system: '03 is common rail- the wave of the future. LOTS of power potential here, and should be almost p-pump reliable.



Axles: '03 Switched from Dana/Spicer to American Axles. These are both heavier and stronger, but have fewer aftermarket options.



Engine: aside from injection system, the oiling on the newer engines is a little better-- ESPECIALLY on the HO engines.



Steering: '03 has a much quicker steering ratio, and I think they now use rack-and-pinion.



Track bar: properly designed on the '03s, so you shouldn't have the premature wear of the 2nd Gens.





These are the differences that aren't immediately noticeable-- there are a lot more.

Good summary, Justin. Rack and pinion is for 2WD only.

Dave, from what I've seen your '03 manual will be almost useless on a an '01, better buy a new truck.
