2008 RDX 130k miles.

Strange clicking/tapping noise only in reverse. Its very slight and not a steady frequency. Happens both when reversing and moving and when reversing with car held in place by the brakes.

Anyone experience anything similar? Thoughts?

Thanks....

 

Does it only happen when giving throttle in reverse? i.e. do you still hear it while coasting backwards?

 

Only happening with throttle inputs. I doubt its anything to do with drive components outside of the transmission (since it happens when the car is stationary but throttle inputs are still applied)

 

Check your motor / transmission mounts.

Worn mounts can allow excess engine movement, putting stress on other components. Applying throttle while stationary, only in reverse, makes me think the engine / transmission is moving from the rotational torque. I have had this happen to me in a previous car, albeit in the opposite direction. Anymore more than mild acceleration forward (also when applying throttle while stationary) caused a grinding / rubbing sound. That said, every engine is mounted differently.
