From your title "noise?" and your description "thump, thump, thump", there is not much to go on.

It is wheel speed related, engine speed related, irratic or rhythmic, 2WD vs 4WD, only when turning, ect?

Engine Mounts? Strut Mounts? CVJoints? Something wrapped around either driveshaft? Tire tread separation? Loose shock mount? Some possible culprits.

nothing on driveshafts, tires are good, its is irractic, it doesnt happen all the time, just happens. I noticed it when i hit bumps and just under normal driving, so I guess I will figure it out myself because there aint much to tell that i didnt say in the first post.

Actually that helps a bit...notice you have a lift too. Seems like something that has loosened up in the front struts and or strut assembly.Probably hard to tell with the wieght of the vehicle on the ground. I would jack up the front, remove the tires and look for play in the strut assembly.

I also noticed that you have ALs Upper Control Arms. I know that a while back he was saying that the Ball Joint "could" get loose.

Also, is there any "shake" transmitted thru the steering wheel? The Rack & Pinion assembly has been known to get loose.

Can't always trust your senses when it comes to "thumps". If it is something that is contacting or stressing the uniframe/body, you might feel it from the seat because that is where "you" contact the body.
