I'm replacing a torn outer CV joint boot on a 1997 Nissan Wingroad. I removed the joint from the drive shaft and disassembled it in order to clean it out and pack it with fresh grease. I made a mental note of which way around the cage goes but it's been a few days since I started the job and I'm now unsure of the correct orientation. One edge is flat and the other is beveled (see photos). Can anyone tell me which side should be facing out?
