5017405 – Center Support Bearing – Ford Application – 1.574″ ID – 2.524″ Center Bearing To Base

5017405 -- Ford Center Support Bearing, 1.574 in Bore, 2.524 in Height

Ford's two-piece driveshaft applications across light and medium duty trucks share a family of center support bearings that differ primarily by center-to-base height. The 5017405 runs at 2.524 inches -- fitting between the low-profile 4180-55 at 1.500 inches and the taller 4180-60 at 2.748 inches. This specific height positions the midshaft stub at the correct angle for the Ford tunnel geometry associated with this application. Substituting a bearing with a different height, even by a quarter inch, rotates the driveshaft working angle enough to introduce harmonic vibration at highway speed.

The 1.574-inch bore is standard across the 1350/1410 series Ford applications. Confirm the stub shaft is free of corrosion, ridging, or deformation before pressing the new bearing -- a stub shaft that's been running with a failed bearing often has surface damage that will prevent a proper fit. Clean the stub shaft journal with emery cloth if needed, but do not remove material that would create a loose fit.

Bracket mounting: Ford uses a two-bolt mount pattern on most two-piece shaft applications through this era. Compare bracket hole spacing on the 5017405 to your OE bracket before installation. An incorrectly torqued bracket is a common overlooked detail -- under-torque allows the bearing to shift under load, over-torque crushes the rubber isolator and kills the vibration isolation function.
