What is the torque specs for tightening the nut .
Thats why I did not suggest a torque spec. Most do not understand the procedure which will require almost twice the torque spec to start crushing the sleeve. Then its about preload.The 1970 service manual says 170 minimum for the #9. That’s with the stock crush sleeve not an aftermarket spacer.
might be good to read the service manual and get the procedure.
#1 and #2 housing FSM says 240 minimum.
Agree.... really need the factory service manual to do that one correctly.Thats why I did not suggest a torque spec. Most do not understand the procedure which will require almost twice the torque spec to start crushing the sleeve. Then its about preload.
This is what I was looking for n either mist it or didn’t read it correctly.Using a dial type in lb. torque wrench, shoot for around 25in lbs. of rotating force or pre-load on the pinion bearings. This is the value to rotate the pinion shaft in the carrier housing WITHOUT the differential case/carrier present. Also, do not use the 'breakaway' torque value that's required to 'start' rotating the pinion shaft.

A 3/4" fine thread with a grade 8 nut can be torqued to over the factory spec but does it really need to be that tight?? How much pressure can a thin shim take? How much can the spacer take?mine is a solid sleeve, thanks cranky
New bearings and used bearings are a different rotational torque value. What are you quoting here?Using a dial type in lb. torque wrench, shoot for around 25in lbs. of rotating force or pre-load on the pinion bearings.
