Mazda TSB #SA-007-23b
2021 Mazda CX-3
Affected Component: POWER TRAIN
- Summary
- The rear differential case could develop a crack in the case, as shown below. NOTE: This could affect new vehicles just delivered to the dealer as well as customer vehicles. This concern is caused when the sliding bearing (1) in the coupling (2) is seized and causes the coupling component to fit loosely. The pinion shaft head (3) then contacts the differential case and causes a crack.
