8.75 Solid crush sleeve play?

Do you have a small dial type inch lb torque wrench? You need it to set the pinion bearing preload. As mentioned earlier that's what the solid pinion spacer and shims are used for. For new bearings you shoot for 15-20 inch lbs of drag as indicated on the inch lb torque wrench. I'd just about bet you can find all kinds of video's on YouTube showing how to do it if you want to see it done first.
