I have been experiencing the idle vibration for a little while now. Since I do all of my own work I decided to go ahead and change the top (dog bone) engine mount and the front (active) engine mount. Had to disassemble a bit more than I initially thought for the front mount, but man what a difference. My vibration at idle is gone, and the engine noise in the cabin is quieter.

There were no indications other than the vibration. Engine did not move excessively between gears, nor was there any visible damage. After trying everything else (tune-up, trans fluid and filter, pcv, MAF etc) I decided to change the mounts. At least I could rule them out and know they were good for another 90k.

If you have the vibration and want to try this, do not use aftermarket parts! Anything rubber (mounts, suspension, bushings etc) should always be Toyota.

Hope this helps.

 

There are 2 engine mounts in the front, 1 front and 1 right side

 

Was the vibration in idle only in gear? I get a vibration in idle only drive and it’s driving me crazy

 

Yes in gear and at idle. The mount looked fine but I changed it anyway along with doing other things to get rid of the vibration. The front mount does take a lot more abuse than the side mounts due to drivetrain torque. I did several other things (pcv valve, MAF sensor, trans fluid and filter using synthetic, premium fuel etc.) but the front mount seemed to be the fix. I changed part number 12360 and 12363A. There are 2 other mounts on the left and right side that I did not touch. Not sure what the other poster is saying about 2 front mounts.
