So I have 2007 MCS N14 and I recently noticed a vibration in my front end when accelerating in 3rd and 4th gears and occasionally in 2nd and 5th. My suspicion is the motor mounts because the engine vibrates pretty heavily when at a stop light or idling. I have not noticed the engine itself shifting back and forth when I rev it either. I’ve also suspected the drive axles. I don’t hear any drive axle noises at this point so I’m not sure what to think. I don’t see any visible CV joint leaks although I know they don’t always show signs that they’re bad. Just to add I have recently installed lowering coilovers, front sway bar stabilizer links and adjustable rear lower control arms. I had the alignment done and it handles just fine. My ball joints are in good shape.

If anyone can help that would be great before I go dumping money into new drive axles!

 

sometimes the engine/transmission mount nut gets loose. double check that one.
