Pinion Depth on 8.75 741 case

ok so i got it back together and took it for a spin... holy crap what a difference 3.91's make! it is so much faster!

no noise on accel (slightly more than part throttle)
no noise on decel (foot off pedal)

noise at coast and very light throttle pressure (very light like set your foot on the pedal)

i set the preload on the pinion so that it was very easy t turn but still some resistance (used bearing) maybe to soft even for used bearings?

backlash was .008 on all 4 checking points

using 85-140 gear oil with LSD additive

pattern was like "B" in the picture...
