I found a site that said the real full-float axle and diff on a 1969 W-100 (a Dana 60) was the same one that D-200 and W-200 had. That surprised me, although maybe the 200's had bigger brakes and thicker leaf springs to give them the heavier GVR. Does anybody know if this is true?
In addition, I could find nothing that describes the difference in front axles on the three. I know my W-100 has a live axle with leafsprings that look absolutely monstrous. Does anybody know the differences?
Thank You
Help with rear axle
Actually, the cutoff year was '68. The '61 through
'68 W100's had Dana 60 rear axles and DANA 44 front
axles with 7 or 8 leafs per spring pack. In '69, the
W100 axles were switched to the 5 stud [8.75 rear &
44 front] style. In pre-'69 W100's, the DANA 60 rear
axles were the same as used on the D & W200's
[pre-'69 models]....brake drums & all. Someone can
correct me if I'm mistaken, but there was a change
on the rear brake drums for the '69-'71 DANA 60's.

I beleive that you are correct: I believe that the rear brake drums ARE smaller on a 69 W-100 than are found on W-200 and D-200's. I have seen some D-200's in the boneyard and the rear brake drums really are significantly bigger than on my 69 W-100.
However, the axle housing and the differential pumpkin size and the number of bolts in the diff appear to be identical. A 69 D-100 is significantly smaller in all respects than my 69 W-100, however the brake drums look the same (front and rear).
So correct me if I am wrong, but my theory is that a 69 W-200 has more leaves in the springs (front and rear), bigger brake drums (front and rear), but the same axle (front and rear) and the same Diffs (front and rear) as a W-100. And does that mean the W-100 has the full float rear axle?

The W100 model, in 1969, was re-configured. It was
offered with the 8.75 corporate rear axle that had
5 wheel studs. The front axle [DANA] also had 5 wheel
studs. This is the general consensus/rule. During
model year change-overs though, trucks sometimes
left the factory with "left-over" parts. The drums
on a '68 corporate Sweptline axle may be larger than
the ones from a '69 corporate axle, but both were
the 8.75 5 wheel stud design. Can you verify the
fact that your truck is a true '69 for us? Maybe
someone slung different axles under it along its
life
. Give us more information
on it... i.e. VIN# and we'll go from there.
