Just so that I understand, the D44 axles would just be replacing the
axle shafts and the differential housings ONLY, correct? It would not
be replacing the gearing again?

While we're on the topic....
Since I have upgraded from 28s to 31s, can that cause the engine to
lug or ping? I generally keep the RPM's around 2200-2400 in 5th gear
(I have a 6 speed). In the higher gears after the engine is warm and
mainly while going uphill (little or big), I get this noise on the
passenger side that sounds VERY similar to the soft top side window
'pinging' against the metal support bow when the wind blows. I can't
quite distinguish if that's it, or if the engine is pinging because I
am not 100% sure whether it's coming from the front or the back. It's
a high-pitched noise. It is NOT rhythmic or steady, but rather comes
and goes intermittently. This noise does NOT happen at city/town
speeds of 50 mph or lower. I ran a tank of 89 through her, and it
seemed to be drastically reduced after 1/4 of the tank was used and
for the rest of the 3/4 of the tank. I have now refilled again with
the 89 and the noise is back. I have not used 1/4 of the tank yet, so
I don't know if it will be reduced again once I get to that point. I
do have a tendecy to 'stuff' as much gas in the tank as I can get
(even after the automatic shuf-off on the spout kicks on). Would this
be causing the problem too?

No.

A Dana 44 is a complete housing that includes the case, the gears, the
axles, the brake mounting plate, the emergency brake, everything must be
changed including the brake shoes or pads.

D35 gears don't fit a D44, they are a different size.

Not sure about the driveshaft.

If you have ABS, then things get even more complex.

I do not have ABS.

TW -- How complicated would it be to just switch out the axles like
you're suggesting? Would this be easier than just upgrading the
gearing? Or does everything that Mike mentioned have to be changed
too even if you just upgrade the gearing from stock to 4.11? Would I
need D44 for the front AND rear? Or do I just change the rear 35s to
44s and leave the 30 in the front?
