So I'm sure this has been asked before and that perhaps it's common knowledge to some, but I've been unable to find a solid answer through a search. Essentially I'm just wondering if it's safe to lift the front end via this cross member. I've done so several times now and have not observed anything unusual. I've also lifted the rear underneath the differential. Is that safe to do as well or am I totally wrong?

I use the rear diff or on the frame under the motor in front of where you have it jacked up in the photo where the front plastic skid shield ends and and the metal one begins

Me too.
I use a 4x4 post to spread load and also give just a little extra lift.

I use the rear diff to jack the rear, frame rails to lift the front
Same here. I try and avoid any kind of lumber between my jack and the frame. I bought a high-lift jack so I can get my vehicle high enough.

I agree I also avoid lumber at least nothing bigger than a 2x4....
Where can you put a Hi lift jack on a Tahoe / Yukon??? I have a hi lift but, I also have steel bumpers front and rear. However I still don't use the hi lift because the frame flexes and the bumper will crack the tail light. I have hooks for the wheels but, it would take and extreme reason to use the hooks on my cast wheels too. So admittedly my hi lift never gets used.
Let me clarify. By High Lift, I mean a floor jack with an extended lifting range like the red one in the photo below. I am not talking about a farm jack or off-road jack. I apologize if I caused any confusion with my choice of terminology.
these are pretty slick too if you have a use for them takes 3 seconds to jack a vehicle up

Jack I bought 20yrs ago came with a second saddle.... can’t say ive ever used it but i have it.... as a matter of fct i just found it in my bsmt the other day....this is exactly the one i have.... although mine looks new. Jack is heavy tho.... hmmm maybe its tome for something new.....
These look a little more trust worthy than the orange punching bag looking thing.

Trailer hitch seems to be a viable jacking point.

I wonder how stable those would be in the dirt? It might come in handy for a quick change while off road... I can just see this now get a flat pop that out up in seconds get out the air impact and tire is changed in pit stop fashion... My onboard air could handle this easy...

They specify their utility in dirt, mud, water, etc. Of course, they also list a handful of CYA's lol.

i thought our hitches only had a 1,000 lb tongue rating? wouldn't raising it by the hitch exceed it by a few thousand pounds?

That's pulling down on an extension tongue, not lifting up on the receiver. Putting a jack under the reciever (2" square box opening) would be much the same as using a weight distributing hitch, which lifts the rear and puts more weight on the front axles.
I've used a floor jack under the reciever on my 2001 to lift the rear when rotating the tires after the front has jackstands under the control arms. Done it 2x a year for the past 10+ years with no problems.

I didn't see anything bend, so eff it.
FWIW, It didn't have the weight of the rear axle or spare on it. lol
I was lifting the body up to get more space to snake the exhaust pipe out, going over the axle.

Not sure who makes our hitches but that method is ok for Curt

I lifted mine with a farm jack on the hitch and my steel bumper flexed the frame enough to crack my rear tail light.. It moved about 1/2 inch... For the back end I just lift the differential and toss jack stands under there...
