Do balancing shops balance these things with the guibos attached? I disagree that you need to have the drive shaft balanced every time you replace what is a consumable item. I've replaced many, many guibos on more than one Alfetta/GTV6//Milano, and never had an issue introduced as a result.

One shouldn't really replace any giubos without balancing the shaft professionally. I have had some luck with using strategically placed hose clamps on the shaft (the screw-tightening type) but while that method can lessen the shake to a tremendous degree, and make it acceptable, it's nothing like getting the shaft professionally balanced as a unit. > > George Graves > '86 GTV-6 3.0 'S' > > > > > On Nov 1, 2011, at 2:18 PM, Brian Shorey wrote: > >> I've heard the Alfa nut balancing theory more than once.
