Me either until the Verde I just finished pulling all the parts off of last night! One of the rear Guibo bolts had an extra washer on it (and a thick one too). Must have been on purpose as the car ran and revved smooth. All the others (and there have been quite a few) all looked the same to me. I have seen a few hose clamps :-).

I've heard the Alfa nut balancing theory more than once.  I think I've only
ever seen one instance where a washer was visibly thicker than the rest of

matter which way they go.

And quite frankly, would this really indicate that there is no option but to
rebalance a drive shaft assembly should you ever strip a bolt and need to
replace it?

I think Chris is correct on this one.  As I understand it, the transaxle
propeller shaft is balanced as an assembly.   I do not think this includes
hardware or the yokes at either end of the shaft.  Having said that, the shop
manuals I have mention marking the yokes and the shaft prior to disassembly
and re-assembling them accordingly.  Of course, doing so could not hurt at
all!


I don't know about Alfas, but SOME cars (late Volvos, for one) used
driveshaft flange bolts with different thickness heads as a way to balance the
shaft assembly. Therefore--BEST to mark EVERYTHING, including the hardware,
and keep it all in the same place !!
