Re: Dana 30 gear noise
Mispoke previously, pls ignore.
From the Dana Light Axle Service Manual:
Pinion nut is torqued between 160-500 ft-lb. With the wheels up and
straight, check the drive torque on the pinion nut. This should be
between 24 and 41 in-lb. (Preload calculated as: 15-30 for the pinion
bearing, 3 more for the seal, 6-12 for differential bearing preload).

Re: Dana 30 gear noise
Do you have any end-play on the yoke? If so, you reached your 160 lb-ft
nut torque (actually the minimum; 500 lb-ft is max with the collapsible
spacer) without meeting your already-collapsed spacer. Incrementally
increasing the torque until end-play is eliminated will likely fix it,
but keep an eye on the preload as you go. If it gets too tight before
you eliminate end-play, you need to start over with a new spacer:
http://xjeep.dyndns.org/danaspicer.pdf
"Torque pinion nut until all end-play is removed and the minimum wrench
torque is achieved. Check torque to rotate of pinion with inch-lb (N.m)
torque wrench for proper rotating torque. See Specification for proper
pinion bearing preload. Continue to tighten in small increments until
the proper rotating torque is achieved. Measure the preload torque
frequently to avoid overtightening of the pinion nut. CAUTION: IF
PRELOAD TORQUE IS EXCEEDED, A NEW COLLAPSIBLE SPACER MUST BE INSTALLED
AND THE TORQUE SEQUENCE REPEATED."

Re: Dana 30 gear noise
Okay, you're describing what I assumed to be the situation.
How am I to measure the preload, I don't have the fancy tool shown in the
shop manual? I just have a regular in-lbs torque wrench - can I repeatedly
lower the setting on that until I reach one that doesn't "click"?
