Q:On a big truck that holds a 3 pc. drive line and has 2 carrier bearings, is it best 2 keep the bearings level?
It is important to keep the bearings square with the drive line. The whole point of having the bearings to support the multiple piece drive line is so that the shaft doesn't need to be absolutely level with the frame, or to be absolutely straight from the transmission to the differential. THE ONLY CRITICAL angle is that the mating surfaces of the transmission and the differential must be within a tolerance of 1-1/2° of each other. The OTHER critical issue is that all of the bearing bosses must be square with each other. If the number 1 joint is positioned at 12 o'clock, then numbers 2 3 must also be at the same index or the driveline will grow under load and at speed ( 40 MPH) and will exhibit a server vibration. Good Luck

Q:doo you need a certain kind of grease for bearings and all that for a bike?
Hahaha you chose an amazing time to ask this question! I'm in no way a professional bike rider but just yesterday I ventured to replace one of my bottom bracket bearings. I was told to use thick grease, NOT oil (if that's even a question in your mind...probably not though). I successfully took it all apart, removed the grease that was in there (there was a LOT) and put the one new bearing in and the old one, along with a good amount of black general purpose grease. It worked flawlessly too, I've been riding it around all day with no problem. Hope that helped! And good luck with your shop :)
