Synchronizer Hub: Testing and Inspection
1. Inspect gear teeth on all synchro hubs and sleeves for rounded off corners, which indicate wear.
2. Install each hub in its mating sleeve and check for freedom of movement.
NOTE: If replacement is required, always replace the synchro sleeve and hub as a set.
