differential spider gears
(OP)
Does anyone know how much clearance is considered normal between the back of the spider gears and the carrier thrust surface on a mid 90's chevrolet pick up truck differential? Also if the spider gears have to much end play at the thrust surface would this cause a whine to come from the differential?
Thank you in advance for any help.

I've just checked our workshop manual for a different vehicle, and to my surprisethe spider-gear end-play isn't given, and isn't adjustable, so I don't know how to help you there - I guess you could look at the wear pattern on the teeth and check that it is central.

RE: differential spider gears
Diff whine usually is worse on cruise or trailing throttle, at some specific speed, rather than at all speeds. Could it be the gearbox? (try shifting into neutral). Have you stuffed around with anything else since the noise started?

RE: differential spider gears
Some causes---incorrect pinion spacer, wrong preload sleeve or wrong preload torque, incorrect lash setting, incorrect preload on carrier bearings, broken or chipped teeth, incorrect axel allignment(bent housing) in side gears, broken spyder gears, bad bearings, wrong lubricant and a lot more I can't think of right now.
Anyway, good luck. It is still one of the 'Black Arts'.
