Welcome to the forum!
When do you hear the clunking noise, while driving, only when hitting bumps, only when turning, only when accelerating, etc.?
Is the clunk periodic, or completely random? If periodic, does it change with engine speed? Is it more of a rumble?

Thank ffor the welcome,
It started clunking when you first took off and then when you would get up to speed around 40 or so it would be gone, now it seems as though it is lasting longer and it is more radom but more at times when you accelerate or sometimes when you break. But even slowng down without braking it can clunk. When it clunks you can feel jarring too. The gas mileage throughout this time has gone way down hill. I also seeing more slipping on the road like perhaps it is not AWD , I can sometimes try to stop and end completely sliding doing a
360. The tires are decent about 8000 miles on them, although we live in "Snow Country" shouldn't be sliding if it were AWD. Thanks for your reply. :banghead:

Well, AWD will not help you during braking. If you are sliding around during braking, that is more related to your ABS or standard brakes. You may have a caliper that is not releasing completely, or one that is not working at all.
Do you know if your Mountaineer has rear disc or rear drum brakes? If rear drum, you may have a leaking wheel cylinder or axle seal that is causing the brake shoes to become contaminated and grab.
I don't know that any sort of traction control was available on the Mountaineer in 1997, but if yours has traction control, you may have a wheel speed sensor that is not working and causing the clunking (traction control attemption to compensate for a what it thinks is a non-rotating wheel). Such an issue could also explain the poor fuel economy.
Your "clunking" also be due to a misfire, but I would suggest inspecting the braking system first.
If you're comfortable inspecting the brakes yourself, start by pulling wheels and making sure the brake pads are all wearing evenly. If rear drum brakes, pull the drums and inspect for contamination from brake fluid or axle grease. If either, you'll need to fix the source of the leak, then replace the brake pads. You'll never be able to get the pads cleaned up well enough to not grab or make noise.
