Best Source For a New Rear Drive Shaft?

[tempest411]

Hello,


I'm chasing a peculiar vibration that began after I did some work on my '03 4.4 last December. This work included changing the center support bearing and rear CV joint. It's a high frequency vibration that 'comes and goes' between 40 and 60mph. Before I condemn the drive shaft I'm going to have all the wheels checked for balance as I did a repair on one of the tires with a tire plug at the same time. I don't think it could be that, but wouldn't it be great if it was? If it is the rear drive shaft, which I think is the only thing it could be at that point, I'd like to buy a whole new shaft, but new OE shafts a very expensive ($1700) and, according to some sources are no longer available anyway. What's left seems to be shafts made by Powertrain Industries. Despite their claims they are U.S. made, all the critical parts such as yokes and rear CV joint are from China. Has anyone used one of these shafts? I can't find any reviews anywhere online.
