    Q:
    What are the symptoms and tests for identifying wear in Universal Joint on Chevrolet Caprice? Posted by Nb N.
    A:
    Wear in needle roller bearings can be identified by various symptoms such as vibration in the transmission, clonks during drive engagement, metallic squeaking, and eventually grating and shrieking sounds as the bearings deteriorate. To check for wear, one can try turning the shaft with one hand while holding the rear axle flange or front half coupling with the other hand to detect any movement between the shaft and the couplings. Another test involves attempting to lift the shaft and observing any movement between the yokes of the joints. If significant wear is observed, it is recommended to either replace the universal joints or opt for a new driveshaft assembly.
