The clunk is coming from rear but sometimes seems to come from the front and at times from t-case/trans area. It happens mostly when accelerating from dead stop but at times accurse while in motion.This has been accruing for about a year and has got a lot worse as of recently.(it is not the u-joints)
I am getting a bad clunk from drive train on 1999 Jeep Cherokee
