No, this isn't how a Wrangler normally behaves. If WalMart had done a poor job of balancing the tires (and the tires are the cause of the problem), then the symptoms might have changed but they wouldn't remain the same.
I would suggest that it might be a worn universal joint on the propeller shaft, but it's really hard to make an accurate guess at this distance. Why not have a mechanic ride with you so that you can point out the noise first hand?

Could Walmart have not done it correctly, or do we have another problem, or is this just how jeeps behave?
Sounds like tire noise to me. The tires may be cupped or have some other odd wear pattern. FWIW, I also think that a competent inspection would have revealed the problem prior to purchase.

High speed shakes due to tire problems are pretty rare.
Not as rare as a real mechanic at Wally World.
Not impossible, just not the first place I would look.
I would look into other drive line problems.
There are eight universal joints on these little Jeeps. any one can cause this.
Any other loose or worn drive line components ie. motor, transmission, transfer case momounts... Clutch pressure plate, throw-out bearing...wheel bearings...ect.
Get a creeper, a light and a rag...crawl around under the Jeep...wiggle things an look for stuff that looks wrong.
Get to know and love the dirty bits of you Jeep as much as the shiny parts.
Good luck and Happy Jeepin'

Well with the very very limited car knowledge that I have (apologies), I have discovered that the vibration tone is altered if I just touch the 4wd lever, which suggests the vibration is coming in that direction. I am guessing the problem could be something as simple as the loosish lever vibrating against something, or is this a sign of a far scarier problem? I know this sounds like something that a mechanic needs to look at but I wanted some advice here to at least sound like I know what I am talkng about! (We had the wheel balance re-checked and all is fine)

thanks for the tip. I have discovered driving that by touching my hand to the 4wd commandtrac lever, the vibration alters in tone. Can this narrow the issue down to something or do I need to take this to a mechanic who knows what they are talking about? If you can at least throw me some possible reasons I can pretend to know what I am talking about! Sorry, my mechanical skills are not great. Could the vibration be something as simple as a wobbly command trac lever or something more scary?

As I suggested earlier, a worn propeller shaft joint could be indicated. The rear propshaft is connected to the transfer case, to which the 4WD selection lever is attached, though as you say it could just be a loose lever.
Also, vibration problems of this nature often occur when a Jeep has been lifted. Has yours been modified in any way?

Mac, you thinking driveline vibes from a lift? Even a budget spacer boost could do that I guess. Each Jeep seems a bit different and it isn't unheard of...

It's a possibility. Even identically specified Jeeps can react differently to the same lift. Diagnosing odd vibrations over the internet is intuitive guesswork at best. There no substitute for seeing the vehicle and experiencing the problem, but doing it here requires starting with the obvious and working towards the less likely.

try checking the heater control valve and the blend doors in the heater box. hope this will fix your heat
#635 of 1888 Oil pump
Aug 15, 2006 (3:41 pm)
I have a 2000 Jeep Wrangler Sahara that's had low oil pressure lately(20 lbs), so after changing the sender unit (no help), and trying an aftermarket oil gauge (same), I changed the oil pump. Now that everything is back together, I have NO oil pressure. (And yes, I put oil in it). Any thoughts? Any help?
