I need to replace my #3 motor mount (passenger side). But I just wanted to make sure im getting the right part from a local part store.
I know there are other aftermarket upgrades available, but I need to change this out ASAP.

Can someone confirm what mounts are in the picture?



Here is what I think goes where, correct me if im wrong.

A = Drivers side mount
B = Passenger side mount without bracket
C = Complete passenger side mount assembly
D = Rear mount


So if I wanted a direct swap would I just purchase mount C? Im just confused cause Rockauto.com shows 4 mounts for the M3i.
And it doesnt help that Technical Service Bulletin for motor mount shows only Mount #1 (rear), Mount #3 (passenger), and Mount #4 (driver). Its missing a number 2!

Any help is appreciated. Thanks in adavance!



*edit:

Just for future reference, I have found that my initial observations were correct. #B is the #3 mount without the bracket, so you have to reuse your old one.
#C is also the #3 mount, but its the complete assembly. You just swap the whole part, with your old one. It was really easy to fix.

 

Help please I have a 2010 mazda 3 and i have travelled down dirt roads and now it makes a very load noise when in reverse and my foot is on the break only? Took it into mazda and they told me its just rocks and to go though a car wash to get them out. did it and its still there could this be the problem?

 

Mine would make a grinding/rattling/vibration noise only when the vehicle was in gear and upon acceleration.
Sometimes it also sounded like a loose exhuast heat shield. Or like I had an aftermarket muffler installed.

Replacing the #3 motor mount fixed the problem. If the dirt road had alot of ruts and holes the engine may have moved enough to cause the mount failure.
Look inside your engine comparment, on the passenger side near the coolant tank is the #3 mount.
Check if its physically damaged or loose. Also look for signs of a fluid leak at the mount. Usually they explode and spray hydraulic fluid when they break.
