Dynatrac should know this. ??????? Jack up your front end and remove your tires, you'll see what I'm talking about. If you do indeed have a C&C you'll see the splines where the axle splines would slip into, in fact all you need to do is remove your hubcaps and see it. Dynatrac should be aware of this, and have the supplier put it in writing, if your getting them direct from Dynatrac have an email trail about this subject. As I noted, the newer 2WD's 2500/3500 have the solid axle in front, they just deleted the pumpkin and axles. But it will be the same front ends as the 4WD. If you want, I'm close to rotating my tires, and I'll email you pictures of the ball joints from my 07 C&C and you can compare. The dealer parts guy should just have to input your VIN, and print the part numbers.
