Yes, I'm running the Tom Woods MDC ones, I also have a compound angle in the front of the truck which is why I use them...
Marc, call BS if you want but, I don't have any vibes caused by the driveshafts... Rims, tires, and some thing else going on at 70mph-75mph yes but, that isn't from the drive shafts since I've had the issue with my old GBR DC shafts, the TW MDC shafts, and I had the pinion angle corrected (up/down) for the DC shaft (except the side to side angle) .. Now I have the front corrected for castor and use the MDC shaft and it works for me. I've had the truck setup this way for at least the last 4 years.
Now, I'm not saying that running MDC shafts is the right way of doing it... Setting the pinion angle, correcting the castor via the swivel balls, and getting the pinion lined up with the transfer case via a longer pan hard rod would be the way to do it.. Doing that however, may also cause you to have to move your passenger side cat convertor out of the way.. That's the problem that I have... There just isn't any room for me to move the axle back to where it should be and none of the exhaust folks around here want to touch the cat and the ones that will I don't want touching it ( if you know what I mean )... Not to mention, where to move it? Plus, I'm not sure if I'm going to change the lift height or not..
