CAD Axle
hi i was lookin at a 99 dodge 3/4 ton with a buddy and he said he put in a new CAD front axle with an outer shaft :humm:and i aint sure what it is never heard about it and the outer shaft makes me think of lock out hubs thanks in advance

on that vintage dodge, the front axle uses a central axle disconnect (CAD). the passenger side axle is split in 2 pieces. there is a vacuum operated shift motor that moves a collar internally to lock the 2 halves of the axle together, giving you 4x4.
the CAD probably came about for fuel economy reasons, the less parts that are spinning and all that. but they built in more parts to break or wear out! the outer shaft refers to the shaft that is in the hub. inner shaft is the shaft immediately inbord of the outer shaft. these to are connected by the u-joint. intermediate shaft is that passenger axle between the side gear and CAD. |
What's sad is the CAD axle doesn't help that much, if any, in the fuel milage area and has more parts to wear out and fail! Just one more brilliant idea of some engineer!!!:argh:

like a pair of lockout hubs is fewer parts to wear out and fail?

They seem to have less trouble and they are easy to fix when they do have problems!:tu: |
yeah you just buy new ones for 200 bucks a pair.

I'll just stick with my noncad axle and not worry about it. Truly fewer parts to wear out and have to replace.

nah. all you have to do is drop the front driveshaft. Its only like 8 bolts? :tttt:
LO hubs would be nice, but the times i use 2wd low is rare. its nice to have a really tight convertor. just have to ride the brakes a lot. |
