[Rovernet] [spam] Vibrations galore

[Michael Pellow]

Had the same thing happen to a friends car after he had the drive shaft 
U js done. Stupid company polished off the arrows aligning the splined 
joint ,and aligned the Universal Joints so they were at 90Degrees  .The 
vibration was so bad that at 100k he couldn’t keep it in a straight 
line.they need to be set up as per the V8 manual Yoke is angular 
displacement Final Drive Suffix A  107 Degrees. Suffix B onwards  144 
degrees.This compensates for the shaft not being in a straight line 
between the gearbox and the back of the diff.
He took it back to them with the copy from my work shop manual.After 
they had done it ,the car was transformed .
As you have had the drive shaft modified ,you can guarantee that the 
alignment  is no longer correct ..
I could scan the instruction ,but I am not sure that I can but them on 
this site
