On a set of Motive 4:10's......with the basic GM crush Sleeve.... (non Ratech) what should the Proper Pinion torque be? THe manual says 96FT Lbs...is that ok to use on a set of 4:10's?

lol's no really i like to post the differential questions here and in the lt1- tech threads...only because different people hang out on different threads and you can get more info that way. sometimes if i ask a question here no one may read it...but if i post the question in the tech thread it'll have like 8 replies...didn't really pay much attention to my 600 post till you mentionrf it though lol's.

You tighten it untill you get 20 to 25 IN LBS of preload on the pinion bearings!!(new bearings of corse) There is no torque spec for the pinion nut.........
Its tight as hell if you never have done it.

The torque spec on the pinion nut for my set of Precision Gears 3.73 was 125 ft. lbs. Don't know if it's the same for the Motive Gears. Oh yeah, i also used a solid pinion spacer.

Like he said.

Yes, you need to measure pinion bearing preload not pinion nut torque.
