My NP231 t-case began whining while in 2wd, it's louder in 4wd. It increases with speed. Disconnected front driveshaft, it goes away. CV joint appears to be in good shape no slop. I used a stethoscope and thought I had it narrowed down to the front output shaft bearing. There was a very slight up & down movement to the front output shaft.
I ordered an overhaul kit (all new bearings & seals) and installed it today. The noise is still there.
What are the symptoms of a stretched chain or a bad planetary gear set? How do you check these items. Everything looked normal during install.
Thanks
