No.
No explosion is going to happen.
No, you do not need to call in the bomb squad to "disarm" it.
Infact you do not need to pay anything near what they may cost (300-$400).
OKAY, I realize I'm a little late on this thread, but lets get going:
First let me get this straight, you have a jeep, it worked fine...then you did something and it didn't. right? Okay, well obviously the problem arises from work you did to the gears.
From here, you need to figure what could have got mixed/messed up to cause this problem.
Now, from what I gather, you pulled the axles and carrier to change the axle seals. It's hard to imagine what you did wrong, but it sounds like somehow the backlash got messed up. Often gears will whine if the backlash has been set too tight (or if there is none at all). Since the gears were aftermarket (4.56's) it's possible that there were shims on the outside of each bearing race, rather than between the bearing and carrier. If this is true, then a simple mix up of these could cause the problem.
From what you say, I doubt that a race mixup is the problem...From the diff did you ONLY remove 2 races, 1 carrier, and 2 bearing caps?
Go ahead and turn the pinion by hand. Does it turn smooth? Is it tight, if you move it clockwise and counter-clockwise, is there a tiny bit of slop? Compare the front diff and rear (should be very similar).
Don't go pay some one $400. That's a HUGE waste of money, you can fix this, yeah it's a pain, but think about how much your learning, and maybe when it's all said and done you'll feel confident enough to install those rear 4.56's yourself!
Do you have full time 4x4 in you jeep? Because if not, put you front D-shaft back on and leave it on. Your not hurting anything with different gears front and rear, UNTILL you put it in 4x4.
Also, front D-shaft or none, thick gear oil or thin....these will not fix the problem.
Good luck,
Jordan

). You got taken for your money, but I'm glad you have the problem solved.
