clunking noise

ok it is a 93 with 230,000 miles some times it sounds like it is coming from the rear sometimes the front right just had front wheel bearings changed thought that may be the problem but continues. I do notice it more often on bumpy roads then smooth ones but it will do it while driving the expressway no set speed of when it happens but when on the highway it will only happen about every 10 or 20 miles. it is like a little hiccup no big jerking or anything like that, and the engine runs smooth could it be the rear axle or the transfer case. hoping not for either of those can be a pricey fix even for a diy'er like me. changed the rear u-joints doesn't seem to make any difference on what I change and summer is just around the corner and trying to get it ready for camping season. hoping for a great summer. lol

and no I have no bowling ball in the trunk I wish it was that simple
