Is there a certain speed it's doing this or under any specific use? Also, forward and reverse?

happens around 55 -60 mph upwards,driving straight

Was the drive shaft put in right?
Is there a chance of a bad U joint?
There is also a big ball joint that is up top that may be bad, better have it checked too.

shaft is ok,
will check closer about the other 2,didnt have a shake before i changed the axle,but then again,was taken apart ,so maybe something not right,who knows,have too change the tyres any ways,get them balanced,rule tyres out,my gut feeling telling me its something else,what i dont know,check under neat but didnt see much,will have a closer look

Clock your shaft 180 degrees. Sometimes that will solve imbalance issues in the rear.

you could have a frozen rear brake caliper.. These engines have a lot of torque so it is hard to feel the drag. While on an incline stopped put your jeep in nuetral take your foot off the brake, it should roll if its does'nt you got a frozen caliper. You could have pinched one of the brake lines during the axel swap. Also feel the wheels if one is hotter than the other that will point to a frozen caliper. Or if you have an inffered thermometer check the temp between the two rear wheels. They should be Identical.

Rear discs? Make sure a parking brake shoe didn't come loose. Happened to me once and caused vibration as the loose shoe spun around to the attached shoe.

The 2002 does not have disks at the rear, unless the OP changed to disks when replacing the rear axle.

The 2002 CRD Sport has an LSD diff...I presume if the diff was replaced with the same type that the correct friction modifier was put in, although that should not cause this type of problem I should think?

I agree with the advice of rotating the drive shaft 180 degrees!
