Hello Brickboarders!

Yesterday I had a drive shaft machine shop taking care of a drive shaft vibration.(940 Turbo wagon 1996 with only 125.000 km's) They did a torque test and all the universals were fine, but the support bearing was no good and the rubber housing very soft and cracked. The drive shaft has been electronically balanced too. It now seems that the vibration has virtually gone. (I'm still not entirely happy!) but for all the money spend I got an irritating noise in return. Particularly in 1st gear (auto tranny)and driving slow there is a whining noise. Also when you brake near an intersection or traffic light and the tranny shifts back into 1st gear. Never heard this noise before. I jacked up the car myself this afternoon and loosened the bolts on the support bracket for the support bearing and re-positioned drive shaft. Not much of a change. It's bugging me because I paid good money and got a problem back! Could the new (much stiffer) rubber housing transmit the tranny noise (sort of planetary wheels noise, that was already there, but was not noticed because of the soft and worn out old support housing?? I suppose that a specialist shop aligned the drive shaft properly according to the marks and didn't muck up the sequense of bolts, etc. Has anyone got some ideas??
