Opinions needed on 72 to 75 D100 or W100 Dodge Truck

On the W100 72-4 will be part time 4wd and 75-up will be full time.

What do you mean part time vs full time 4wd?

As far's I'm concerned, the wheel bearing design of the full time Dodges is absolute junk. This is a matched pair of Timken bearings, requiring a press to change them. There is no adjustment as on the older trucks and GM / Ford, and worse, the bearings are very close together, meaning wide wheels put more stress and leverage on the bearings.

Also at some point, Ma's idea of 4wd 'disconnect' was a completely STUPID device in the AXLE which disconnected half of one side of the axle from the other.........leaving the ring an pinion to continue to spin.

This mess. The ring at bottom right is supposed to be "precision ground" making the entire set "a set" you cannot replace just one bearing

Below is an 85? housing I found on ebay, showing the axle disconnector mount

Well, all that does not seem like fun at all. LOL

Nope not a lot of aftermarket support.
75 W100 will have disc. Not sure about 74.
On my 73 W200 I converted the drums to Chevy disc and is an easy conversion. Not real sure about the W100.
The 72-93 trucks are the same platform.
D100 were available with disc starting in 72.

Yeah, I can't seem to find much aftermarket parts and information about 70's Dodge trucks. It's a shame because they're very nice looking trucks.

I don't know what kind of suspension 70's era 4x4 use. Is it leaf springs in the front as well? What about transmissions and transfer cases? I don't know where to go to find this kind of info.

Thanks guys for the info thus far!
