KJ Verada GTV Series 2.

So i have this annoying vibration that is most noticeable on hard acceleration. The "shudder" is a feeling that comes through the floor only, front of car, not felt through the steering wheel. This feeling is similar to a diff shudder or minor axle hopping feeling, and as i said mainly happens in high torque situations. However is noticable nearly all the time during normal driving.

Tiptronic gearbox, shudders in both manual and auto shifting.

Over the last week i have done the following :
-Replace both CV/Driveshafts with new kits. Including ABS rings
-Replace Rear and FS engine mounts
-Wheel alignment and balance.
-New tyres front
-Engine belts
-Full service, engine and gearbox.
-New rocker cover gaskets.

This problem was there before the work was done.(i thought it would be driveshaft for sure) And it is still there now................ANY suggestions what this could be.

My last thought - Wheel bearings, but they are not noisy!

So it pretty much happens under load? Two common causes:

1. Clean your MAF sensor, buy a cleaner from autobarn, you will have to take it out of your intake (not hard to do)
2. Your distributor cap & rotor might need replacing

Both of those will cause shudder under load....
