Hi all I'm new to the forum, I bought a 89 jeep wagoneer I no I no its not a cherokee but close enough anyways when I shift from 2wheel to full time it lags lack of a better word in part time then when it decides to finnaly shift into fulltime it makes a loud clunk from the t-case, ujoints are good do I need to rebuild this tcase or is this normal I'm used to the 232 in former jeeps. Any help is greatly appriciated o did a flush tonight its still does it
