I have a question regarding setting preload on passenger side.
I set the pinion angle on drivers side at 2degrees down, getting my measurements from driveshaft and inion yoke but want to set neutral preload.

I installed this setup, so am I just turning the lower adjuster with a wrench to get the bolt to slide freely in and out from the front eyehole? I have my son in the driver seat for proper weight.
