Could this be the remedy my humming/driveline problems?

Ive thought that the humming noise could be a motor mount so maybe this could fix both of my problems??? When I search rear motor mount I just find transmission mounts? Do we have a rear motor mount? And are these a pain in the ass to replace? Thanks for any info guys!!!

 

Nobody? C'mon guys!

 

We can't give you any feedback without information....

If it humms & vibrates....could be a lot of different things.

What exactly is happening?

 

Ok so my 07 has been making a front end humming noise for about 10 months. The reason I have let it go so long is because it only presents itself when it is below 60 degrees outside. It only does it when the engine is around 1200-1500 rpm and as soon as you give it more gas or let off it disappears?? It is driving me insane and I cant figure out what it is. I replaced the passenger wheel bearing last year so I know what that sounds like. Im thinking that the rubber on the motor mount is shrinking during the colder weather and possibly causing metal to metal contact. Toyota is supposed to check it out tomorrow but I doubt they can tell if its the mount without removing it.
