while driving i hear on occasion a loud clunking, sound like something binding up or something it usally only last a few seconds. the problem has gotten worse i have crawled under the rig and attempted to locate duplicate the noise but to no avail. any help on this would be awesome. thanx  

its probably the engine.wat kinda tires u got on there?because Ive had super swampers before and and the made a clunking sound.and make sure to check the tires aren't to big for the axles!  

there only 31" all terrain tires. and the noise only occurs while driving at road speeds off roading it makes no noise. it started off only doing it on ruff roads and now seems like it does it when ever it wants  

I would start by check Ujoints, Big tires without regearing places a lot of strain on drive line and taxes Ujoints more. A little bit of slop/wear in joints will be stressed more and the drive shafts with amplify the sounds they make.  

dude get bigger tires[mud terrains more preferred] and a wider axle with a 12 or 14 inch lift.now im only a beginner at offroading so im not really sure but that's my simple idea.  

front axle u-joints, ball joints and wheel bearings new as of one year ago same as the needle bearings inside of the spindles.(had to do ball joints and decided to do all of it)same as all the seals, it seams to occur only when at road speeds and in 2 wheel drive, primarily on a ruff road, but it doesn't cause any crazy handling. i was thinking it could be ether the front axle pivot bushings or maybe the rear wheel bearings but i dont know. if i had the $$$ i would rebuild the whole driveline. but i don't  

Recheck Ujoints. A lot can happen to them in a rear with a lift. I have seen them fail in less than one year many times in some apps.  

my friend had this problem in his 73 ford. it turned out to be his tranny  

If you have auto lockout, they may still be engaged. Happened to my dad. If you can't find out what it is, just wait for it to break. That will make it a lot easier to find.  

there manual super winch hubs. and i was planning on waiting for something to break but winters sneaking up and wrench'n aint as fun below freezing. and my truck is stock cept a few power upgrades.  

Personally I would not wait. That is not best plan of action here.  

dude just take off the lift and all the rest of the *** u got on ther and put it on another truck w/a wide axle.and can anybody plz tell me how to write my own forum?or write  stuff on a page and ask u guys questions without having to ask questions on other guys forums?

No lift on it, and getting another truck is out of the question right now.
