<p>Hi Scott I think that's the torque required to turn the pinion.
Put a socket to fit the pinion nut on a?? inch pound torque wrench;
measure how much torque it takes to turn the pinion. Get it
turning and read the torque wrench while turning it. 12 to 15 inch
pounds sounds ok. With shims either add or remove shims to get the
correct preload. Thicker to lessen and thinner to increase I
think.</p>
<p>With a collapsible spacer it's easier. Keep?? tightening the nut
and measuring the preload until it's right. Small increments. If
you over tighten you take it apart and start over with a new
spacer. (Ask me how I know this!)</p>
<p>Also a "clicker" torque wrench isn't the ticket for this. Use an
older beam type.<br>
</p>
<p>Hope this helps.</p>
<p>Cheers Bill<br>

I???m rebuilding my differential. ??The manual says the pinion
