My 2013 Maxima SV has around 135,000 miles and I am looking to replace my old and broken motor mounts before they get much worse. From what I understand, there are 6 of them.

I am a little confused because on the parts.nissanusa site, I am seeing 7 parts listed under motor mounts (listed below).

Would anyone be able to tell me which ones are the correct part numbers? Are the last two the same things?

Engine Mount (Front)
Part Number: 11270-9N00B

Automatic Transmission Mount (Left, Front)
Part Number: 11220-JA10A

Engine Mount (Right)
Part Number: 11210-9N00A

Insulator Engine Mounting. Motor Mount. (Rear)
Part Number: 11320-9N00A

Buffer Engine Mounting. (Rear)
Part Number: 11360-JA100

Engine Support Rod
Part Number: 11350-9N00A

Rod Torque.
Part Number: 11350-9DF0A

 

You can find a breakdown of each part here with a drawing that is numbered. Definitely helped me:

Unless all of your motor mounts are severely deteriorated I would suggest you only replace the most crucial ones first. That being said, my 2010 Maxima has 186K miles on it and I've only replaced the upper passenger side torque mount in those miles because my engine was noticeably moving under load. I bought the part from a Nissan parts supplier on eBay for about $40. I found a video on YouTube and was able to put it on myself. My car is garage kept so my rubber parts tend to last longer than say a car that is kept outside in a hotter location like Texas or California.

 

Thank you all for the tips! I assumed I had to replace all of them at once. I'll check with my trusted mechanic and see which parts specifically need to be changed.

At the moment there is a fine vibration when I am at a stop light with the shifter in D. I can see ripples forming in the water bottle that is in my cup holder. I tried shifting to P and N but the amount of vibration doesnt change.

Getting on the gas from a stop feels "squishy" if that makes sense. And letting off the gas as I am approaching a stop light, I can feel the engine moving a little bit as well.
