What happens if you torque the yoke nut?
You DON’T torque the yoke nut. The pinion has a crush sleeve in it that – if you over-torque it, will crush excessively and accelerate the gear wear (and it will whine a lot and possibly self destruct if bad enough).
What kind of torque wrench to use on Chevy yoke nut?
On the crush sleeve type rear ends, as our vehicles have, tighten the nut until you get the pinion drag to the correct specification. The beam type inch pound torque wrench I use has a ring on the scale end, so a finger can be used to rotate the wrench while reading the scale.
Can you change the bearing preload on a pinion nut?
If the new yoke and old yoke are as little as .005 inch different in thickness then your pinion bearing preload will be way off. Torquing the nut will not change the bearing preload.
What’s the lock thread on a torque nut?
IT IS SUPPOSED TO BE THAT WAY. The lock thread (whether plastic or a metal crimp style) keeps it from coming undone. Measure the depth of both of the yokes (where the shaft splines are cut into the yoke) to make sure they will fit in place of one another. You can use locktite if you want, but I wouldn’t use red – blue is good enough.
How is torque measured on a pinion nut?
There is no actual torque spec for the pinion nut. You tighten it until you get the correct amount of “drag” (actually called the pinion bearing preload) on the pinion bearing. This is measured in inch lbs with a dial type torque wrench.

How to torque the rear end yoke on a Camaro?
Richmond gear sells them for about $25 bucks. I have also fabricated up a spanner out of 1/4″ plate that is welded into a six foot pipe that bolts to the rear yoke. I then strap the pipe to the axle and have my assistant sit on the end while I torque the nut. ‘Larger Dave’ is giving you the Rotational Pre-Load for the pinion.
