Where can I find a diagram of the Axel& cvshaft on a 2000 Chevy venture?

Here is the pic from the above link. This is the passenger side. The drivers will be mirrored -> the only difference being the cv shaft. Passenger side cv has female splines while the drivers has male. You should be able to turn you steering wheel far right/left and inspect the cv shafts. There should be no movement on the shaft in any direction. It could also be the outer wheel (unit) bearing. Jack up each side and rock the wheel and try to rotate there should be no movement and minimal rotation. If the tire cannot rotate ~1" freely back and forth block the rear wheels and put the van in N and retest, the wheel should rotate freely.
