I'd speculate you jamed your linkage. It's possible you broke a tooth off a gear? You could take a look at your tranny fluid for signs of metal
I ground a gear back in the mid 80's and it has shifted rough ever since but it has never been a problem during the last 20 years?
I'd check it and drive it!

Hard to say on the 4WD issue. Jack it up and look for anything bent or loose. Looks good then put a few miles on it and see whats up.

These are speculations at this point. Check it out and let us know.

I could shift in and out of 4WD just fine, but it wouldn't move in first gear while in 4WD. didn't try 2nd, and I don't think I tried putting it in 4WD low either, but I can't quite remember. and I fixed the fan guard thingy.... the fan was scraping the bottom of the fan guard so I got under the car with a pry-bar and just pulled down on the bottom to pull the dent out..... and that worked (how the dent got there I have no idea). But it was still scraping the edge of the radiator so I just unbolted the top of it and put a couple washers between the actual radiator and the fan guard assembly. Worked out fine, no more noise. I'll get under the car and check out what's up with the 4WD...... and I'll take it to the lake sometime in the next few days and drive around in the gravel in 4WD and let you know if there's anything strange. And the knocking noise is only really noticeable when climbing a steep hill or giving it alot of gas. And what's the normal oil pressure at idle? When I first start it, it stays around 45 psi... but when it's warmed up, it's about at 25-30 psi. Thanks for the help guys.
That would also explain the inability to shift in and out of 4WD.
P.S. I don't think the knocking could be because of the oil pan getting bashed because there's a skid plate there. But it does have some fist-sized holes in it to change oil, access oil filter etc.

look at all your mounts....If your out trashing it that hard, you may have torn a mount up....Would explain all your symtoms ...
Also the way your shift linkage is set up, if you are in heavy clay type mud, and there is gravel mixed in with it, it is rear easy to pump the goo up in and around the linkage, and if there happens to be any fair sized rocks in there, they tend to jam linkage up......
I had to get up under my Hatch twice to dislodge rocks that had managed to get up in there and wedge into my linkage.....
To check your CV Joints.......
Get in a large parking lot, put it in 1st gear,turn hard one way and with your foot on the brake to give it resistance do a few hard turns, then turn the other direction and repeat the process.....If you have one bad that will tell you which one it is....
Have fun, John

Dunno if that's really your problem. With all that thrashing around in the gumbo you might have loosend up the wiring at your fuel pump. That is located in the rear of your vehicle, under neath the unibody, behind the rear main crossmember, infront of the rear passanger side tire. You'll see a triangular plate with 3 bolts which has the fuel pump on top. Might want to check that out and make sure the wires are properly secured.
Could also be ignition cutting out on you. It's really hard to diagnose this stuff over the 'net. You sound adept at going over your vehicle; check some things out and I'm sure you'll figure out the problem

You were referring to the throttle body, but it's carbureted. Is it only the fuel injected versions that have this MAF sensor? I'll look for it anyway and if I can't find it I'll assume it doesn't have one I guess, lol. And I only thrashed it around that once, lol... now I try to stick with just mud and not so much seriously gnarly terrain. Thanks for the info.
Yes only on EFI models. You said MAF so I assumed you were talking about an EFI model...
Still would check out your fuel pump back there.
