The one piece drive shaft will connect to the pinion gear at a different angle then the stock driveshaft. To compensate for this the adjustable LCAs are recommended. The Lower Control Arms (LCA) will need to be shortened to correct the pinion angle. Failure to do so will result in vibration at various speeds. The OEM pinion angle is between -2.7 and -3.

Shortened? I thought they were supposed to be a tad longer...

The Shaftmaster 3.5" d/s clocks in under 17 lbs.

The spyders 16.5 claim seems right. I remember it feeling light. But also, its included pinion flange weighs next to nothing, unlike the stock one

An Adjustable UCA can also change the angle.

Pinion Angle OK
U-Joint Operational Angle OK
Going to try reclocking the shaft tomorrow morning.
My best guess is the "hum" Im feeling is gear murmur from the stock ring and pinion.
If so reclocking the driveshaft should help "tune" it to help cancel this.
I suspect this is why Ford uses a 2 piece with the 8.8".
