I meant like seal, yoke seal washer and nut, and there's vertical slop like you can pick it up and down a little and there's bad sounds and vibrations coming from the entire driveline at highway speeds. I was going to completely rebuild the transfer case and get new driveshafts.

Transmission problems after new radiator installation?
I wonder if anyone else has experienced this. Mine is a '92 XJ and here is a little backstory for context:
I replaced my water pump because it was bad, and so I replaced my radiator because you're supposed to do that when you do a new water pump. So of course I also changed my thermostat and serpentine belt and radiator hoses, but that's beside the point.
Now I'm running with the new radiator and my engine temp seems cooler than before, and goes up to about 210 before dropping to 190. So that tells me that the thermometer and the radiator are doing their thing.
The problem is that the transmission is clunky both when in drive and when going into reverse. Like, I hear a faint "clunk" sound. This has NEVER been a problem before and has only started since yesterday, when I installed the new radiator. My thoughts and questions:

- Could the transmission fluid be TOO COLD as the result of the new radiator?
- How can I test to see that flow is good between the transmission and the radiator? The brass hose gets very hot to the touch, but maybe that's not evidence enough that there's actual fluid in there?
- The brass fitting on the radiator that connects to the tranny had a white piece of plastic with a clip on either side that holds it into the line, and it also had a black piece of plastic that fits on top of the white piece. During the install, I lost the black piece and am just using the white piece with the clip on either side. I see ZERO leakage, so I would think there's no problem. Does that sound right to you?
- Any other ideas?

My horn recently stopped working and my airbag light is on. Some research led to the clock spring possibly being the problem.
I'm going to pull the wheel off and check connections, but I may have to replace it. Any ideas? Or advice?

Sounds like clockspring. pretty easy to do, there are some great youtube videos. Just don't forget to get a steering wheel puller.

Running rough and backfiring
I have a 1990 jeep Cherokee it's been having problems. When I start up the engine after it hasn't been ran for a few hours, it cranks for a while before it finally starts. It runs extremely rough and sputters. If you drive it that way it backfires and has an extreme loss of power. Also bad fuel mileage. Also has an extremely low idle. I'm not kidding it is probably 200rpms I have to put my foot on the gas just to keep it running. After the engine heats up it finally smooths out slowly.
Things I've done to fix it:
Spark plugs/wires
Distributor cap/ rotor
Cleaned throttle body
Replaced iac sensor
Checked map sensor
Checked tps sensor
Checked fuel pump and fuel lines (fuel pressure read 39psi)
I just need help fixing the problem
