Eliminating Mazda Knocking Noise

Feb. 27, 2023

A new design rear differential mount bushing has been released on a cross member to eliminate the knocking noise.

If you encounter a 2013-2016 Mazda CX-5 vehicle that has a knocking noise from the rear of the vehicle, you may find cracks in the rear differential mount bushing. This is caused by insufficient durability of the bushing. To eliminate the noise, the shape of the bushing has been changed. Replace the rear cross member with a modified one according to the instructions on MS3 online.
