The pinion angle should be about the same as what the angle of the
transmission output shaft is, so that the input and output yokes of the
driveshaft are nominally parallel.
Whining is not usually a symptom of pinion angle issues - it is probably
(still) a gearset installation issue, or else there9s a bearing that is no
good.
