On a Wrangler, the most common cause of u-joint wear is incorrect driveline angles. Unfortunately you didn't provide any other details about your driveline setup but this should be a good place to start.
The transmission is not shifting in and out of gear or your front joint is going bad
Wrench or twist the ligaments of (an ankle, wrist, or other joint) violently.

Worn out/bad universal joint(s) in the driveshaft(s).
Must not be installed correctly. If the joint is not perfectly centered it will vibrate.
Well, if it is a front driveshaft, the issue is a CV joint and you'll have to remove the driveshaft and take it in to be rebuilt. Taht will run you $150 or more. If it is a rear driveshaft, it will be cheaper if you remove the driveshaft and take it to a driveline shop where they can press in a new u-joint.....I'd recommend you replace both. A guess? $60 to $80
check driveline, my universal joint went bad and did same, replace and was fine(1990 loyale)
There are several reasons. Two common reasons would be warped brake rotors or a bad ball joint which should be fixed immediatly.
U-joint phasing refers to the alignment of the yokes on either end of a universal joint in a driveshaft. Proper phasing ensures that the components are oriented in the correct position to reduce vibrations and maintain smooth power transfer. When the yokes are out of phase, it can lead to increased wear and potential driveline issues.
