ok, well it all started last week with a loud clicking noise coming from underneath me and speeds after 35 mph, it got louder as i went faster...it sounded like a chain to me and the garage i took it to said the tcase sounds like its bad so i put another one in it. Got it back today and its still making a clicking noise, not as bad as before. but like a ticking as a card in a bike tire. it does it with or with out the clutch in, in neutral or any gear its always there while im moving.. they said it can be the pilot bearing. but i heard they only squeal and what not. Can anyone plz help me and shed some light on what it can be. They checked all my u joints and they said there all good and looked at everything else n said no probs. Its a 94 jeep cherokee 4.0 5 speed.
