I don't want to deal with pulling the cover on my rear end. What are my chances of getting 75w140 gear oil to syphon out? I was just going to try the old-fashioned way with hose, not using a pump (unless you count my lungs as a pump).

Drive it and get it warmed up. You may get it with a hose but a cheap pump will work better.

Use as big of a hose as you can, and for sure get the oil as hot as possible first.
ALso remember that 75-140 gear oil roughly compares to a 20-50 engine oil .

I have drilled & tapped a 10-32 in housing's & cases before with out any troubles. I will use a seal on the shoulder of the screw and after installed I will spread some rtv over it to make or other adhesive to be sure it can't back out.

Ill second with the tap,or you can buy a diff cover with a drain hole on it,they are mostly inexpensive and lots of them can help heat dissipation,pm me if you need a link selling these cover.
The car, 05 Dodge Durango, has a Watts linkage that is attached to the rear end. The diff cover has a boss cast into it that the link bolts to. I wouldn't mind a nice looking aluminum cover, but I'd have to loose Watts link. Hence the syphoning option.

Pretty cool that they put a Watts Link on those trucks!! (It would cost me ~$800.00 to put one on my ride
)
When I owned a T-Bird SC sans drain plug I used to use a Lincoln suction gun to remove old gear oil.

If you plan to keep your truck,got the feeling you do,tap a hole with a magnetic plug ,its worth the trouble .If you are not comfortable doing it yourself just unbolt the cover and bring it to a fab shop,im sure there is a good one nearby your place.
I use a vacuum jar to remove diff fluids. You can make one using a mason jar and jar lid with two holes for poly tubing. I used 1/4" cause it was handy. The holes need to be a tight fit so you dont loose too much suction around them. Connect one hose to an intake maifold fitting (tee or whatever) and put the other end in one hole of the lid (just an inch or so). Put another hose the other hole of the lid, start the engine and start sucking out whatever you want (diff fluid, brake fluid, atf). Watch the level in the jar so you dont send fluids into the engine.
Having warm diff fluid speeds up the process.

Could you post a picture of your set up hsd?
Removing the cover is worth the work because you can clean off the gray slime of death that clings to the gears and bearings after the gear oil is drained.

the silver paste of death ah yes...
+1 to removing the cover.. its not that hard to put some rtv on it after scraping off the old.

Yep I longer suction it out. When I finally opened up the diff cover after 100K all the metal was sitting on the bottom of the diff. It falls out of suspension pretty quick once the gears stop moving.
Need to get most of that stuff out.
