Hello guys, I have a problem with the drive shaft (rear) of my Ford Expedition 4.6L 4WD. It is overall ok but the centering ball is loose and it is clicking by know (I already disassembly the shaft and see this part damage), I’m afraid it can get worse. I went to several “boneyards” but I can’t find a shaft like this. I found a new one for 400 dlls in cardone but I only need a small component of the shaft, the centering ball assembly (you know the one that is inside the nut next to the transmission). The attached file is a JPG of the shaft
