Launch Shutter Cure

[PWelsh]

Just got issue #47 of TDR. Page 109, under "Bad Vibrations" they state that a North Dakota dealership cured the launch shutter by adding two bottles of friction modifier additive (Mopar part # 4318060AB) to the axle. I have a slight shutter but planed to do nothing as it's gone by 5mph. Has anyone else tried this? Did it work?

I tried putting oil on my shutter's and all that it did was make an oily mess on the side of the house.
