I decided to do some PM on my 92 245 w/ m47 and replace the Guibo Flex Disc, both the U joints and the Carrier Bearing. Now I have a vibration around 65-70 mph when I didn't have one before.
I did try and mark the DS assembly to maintain the correct phasing front to rear but there is a possibility that it did not get reassembled correctly as the marks were a little far apart with the carrier bearing and slip joint in the way.
The new Ujoints are Moog brand w/ zerk fittings. Is it possible that the new u-joints with zerk fittings are different enough in weight that its throwing the balance of the shaft off?
Does phasing of the front and rear half of the DS matter that much with the guibo up front? I know its critical w/ the m46 u joint connection.
Is it SOP to have it re balanced after installing new U joints? I wouldn't think it would be that critical...
