Point the pinion shaft at the transfer case. That's one way to say it, but a little more detail might be helpful.
Drive shaft with U-joint U-Joint: The drive shaft angle has to be split evenly between the two ends of the drive shaft.
Drive shaft with U-joint CV: The U-Joint end needs to be straight with the pinion shaft. An angle of 3 or 4 degrees maximum, and that angle needs to be in the direction so that as more weight is put on the Jeep, the angle gets less and less. The other end of the drive shaft, the CV end has ALL the angle of the drive shaft.
Most of the CV joints for the TJ have the flush mounted grease fittings, not a normal Zerks. The CV joint NEEDS to be greased REGULARLY. That's usually the reason they have to be replaced - no grease.
Hope this helps.
