It is normal for P4 to vibrate a little when on full lock, loud bumping/knocking is not. It is because there is no real centrall diff like in 155 Q4 (you Very Happy owner of 1). So difference in rear front speeds/turning circle is compesated by rear tires skiping portions of ground.
New rubber visco coupling mounts would help maybe a little more, but if it's only more then small amount of vibration.

Unfortunatly it seems they are no longer available (along with P4 petrol tanks, bolts to hold P4 rear calipers on, P4 rear gearbox mounts, etc).

All the best

Unfortunaly they are no longer in production for more then 3-4 years, but from time to time some parts can be found with bit of luck and if you look hard enough.
We should probably make all over the world (every look in ther country) search for those parts and buy them, but I know that it will never happen.
