Re: Super Stock Springs Update

On ball and trunions and slip yokes. You must be sure that with car weight 
on the axels, that there is room for the drive shaft to be able to "give" 
frontward and backward. without bottoming out.  With slip yokes, if they are 
to close to the spline ends that will make the yoke loose and definatly make 
a viberation. Also if the yoke splines are worn and loose fitting, that will 
make a vibration.  Even brake shoe drag will make a vibration you would 
think was coming from the driveline...............................MO

I’m no expert by far, but I’d be inclined to agree with your suspicions…that 
is 1. To check drive shaft length / straightness and what about the 
universal(s) joints / Ball Trunion, are these fresh? By a remote chance, 
maybe by simply rotating the drive shaft connecting point could restore 
smooth operation.   And 2. The pinion angle, someone else will know better 
but is the angle of 3 degrees still a commonly accepted point?
