I am slowly getting around to posting some of the information I learned at the SRT-4 Nationals. I had a chance to ask about the two (for me) hose clamps on the yoke of the transmission. Here's how it was explained to me. Be sure to tell your SRT Tech and other owners.
--------------------------------------------------------------------------
The truck drivetrains are dynamically balanced as a system at 140 - 150 mph. The system is spun up with the rear wheels removed using an optical angular position sensor and accelerometers mounted on the tail of the transmission and axle housing. Like a Hunter wheel balancer, the software then tells the operator to install weights (specially sized hose clamps) at certain circumferential locations to properly balance the system. Not every vehicle has these as they may not have been required after testing. There are vehicle-to-vehicle variations.
If service is performed on the vehicle that requires the driveshaft to be removed, the tech should mark a line with a paint marker on the yolk and on the corresponding spline on the male output shaft of the transmission. The system should be reassembled by matching the paint lines.
