What would cause a clunking noise when i engage my 95 jeep cherokee into 4x4 when i start to move?????

could be ujoints. or the linkage/chain in your tcase.

What would cause the ujoints to make the noise??

When you engage 4wd, it puts a load on the front driveshaft, axles, etc. all of which are just freewheeling while in 2wd. The load could cause noises to appear.

how would i figure out the problem??

Make the noise happen in a place where you can have somebody under the vehicle to listen for the noise ( up on jackstands, hoist, anything safe). If you can't find anything conclusive you have 2 options: take it to a professional as in alot of cases they can tell what it is just by hearing it (doesn't have to be a shop either, could be a knowledgeable friend, uncle, what have you), or number 2: start throwing parts at it. I do not recommend number 2 as it can be quite expensive and frustrating.

If I were you, I'd buy a service manual or even just use the search function here or on Naxja and figure out the correct way to adjust the t-case shifter linkage. Hell, maybe you'll get lucky and someone will post the procedure in one of your 3 threads about this issue you're having.

when was the last time you changed any ujoints? maybe give your ds ujoints some grease lovin.
or when was the last time you serviced your tcase?

i have the same thing happin to my xj but my grandpa said it was rack and pinon gear but my nosie happens when i hit the gas and let off the gas.

No rack and pinion in an XJ. Could mean the steering box but I don't know how that would make noise when accelerating unless the steering linkage is f-ed .
