The torque test isn't a conclusive test and many say it's a load of bs.

I rushed today, will make up weight/pole this weekend and re-post.

It is a brand new VCU and I just wanted to see if they had fotted a siezed one due to the new whining noise im experiencing from the IRD area now this has been fitted.
Old VCU is on the bench, will test/video that too this weekend hopefully,
 
Doesn't look seized to me mate, note how the two u joints turn at different rates suggesting that the plates in the viscous fluid are not locked
 
bell engineering text is bollocks you can test viscous isnt siezed by turning rear wheel or tip ex test it is siezed or not ,the torque thats neede to turn it maybe debatable but ive checked new ones with torque wrench and stop watch and they vary, i was told in the 90s when working on borg warners with viscous couplings that as long as they moved they should give differential as unless siezed they would lock the more torque you put through them we asked for specific figures and they said they didnt have any ie siezd or not
