How much does 3 in lbs matter?

When I built the rearend and set up the gears, I crushed the sleeve and went over the spec by 3-4 in lbs. Could this have anything to do with my vibration?

I ask because I could hear a noise in the rearend at the front under the pinion and it did feel rough. However, the pinion doesn't have any play. I also have no metal shavings or anything in the gear oil. I drained it last week when working on the car to check. This roughness and noise happens with speed. At idle in first gear, I hear or feel nothing. At idle in fourth gear, I hear and feel it. This is with the rear off the ground so the tires can spin freely.

I'm just looking at everything since I'm not getting far with this vibration issue. I've determined that it's definitely in the driveshaft and pinion area. I still got the vibration with no axles in the car and only the driveshaft in place.

New u joint didn't change anything.

Thanks
