Front end questions

Today on my way to work the front end of the Jeep was wandering all over the road and I could hear the front tires intermittently screeching. I pulled over and removed the front driveshaft and got going down the road again with now wandering or any of the noises that were present before. Any insight at all is welcome.

Tie rods, ball joints, control arm bushings. Look at and test them.

Is it broken?

What would be the best way to go about testing them?

Just to clarify, its not a "death wobble" type thing. Its intermittent pulsing vibes and the front end wandering all over the road. Without the front driveshaft it drives straight and true which leads me to believe its something in the transfer case or the front differential. Any input at all?

Have a friend turn the wheel back and forth quickly while you're under the front. Look for play in ball joints and tie rod ends. For the control arms put a pry bar in-between arm and frame. You should have a little movement in the bushings given their rubber but too much will cause wondering for sure.

Everything looked looked fine and seemed tight in the front end. It feels as if the pulsing vibrating sounds are coming from the transfer case.

If the vibrations went away with the removal of DS then that's one issue. The wandering would be either ball joints or control arm bushings. I suggest you get the driveshaft situated then reinstall. Then tackle the wandering. In my experience there doesn't seem to be a way the DS could cause or fix a wandering issue. Change the fluid in the TC if it grumbles. Make sure to use the correct fluid.

Also the TC linkage could need an adjustment

The vibrations and the wandering went away when the drive shaft was removed. I guess wandering is not really a good word choice. It's more of a all of a sudden My jeep wants to drive me off into a ditch.

Check the calipers and wheel bearings.

I just put new rotors and calipers on it just a couple of days ago. I recently changed the fluid in the front differential and what little oil was left was no longer oil just sludge.
Could it be something in the front diff causing the sudden change in direction.

If it happened after changing your diff fluid and front brakes, I would look there.

Is the front diff a Varilock, and if so, did you add Friction Modifier? And is it only pulling in one direction? Do the brakes take longer than normal to release after you come to a stop? Are you missing any bolts, I would inspect the calipers.

If you have good jackstands, try to put them under the axles and reproduce it where you can now see and hear the underside.

What kind of shape is the drive shaft in?
Are the u-joints binding or is the CV locking up?
Check it out while you have it out.
