PROPELLER SHAFT AND UNIVERSAL JOINTS

The engine power is transmitted to the rear axle through two tubular propeller shafts,
which permits low center of gravity and smooth operation. The front propeller shaft is
supported near the rear end in an annular ball bearing mounted in rubber to absorb any
vibration and noise. Three universal joints of the needle roller bearing type are employed,
one at the front end of the front shaft, one between the front and rear shafts and another at
the rear end of the rear shaft.
Each universal joint is provided with means of lubricating the needle rollers through
drilled passages and pressure type grease fittings. The splined sleeve of the middle joint is
also lubricated through a pressure fitting. Viscous chassis lubricant should be applied co
these fittings each 1,000 miles, using a hand gun or a special adapter on the lubricating
hose nozzle, to guard against excessive pressures.
The rear axle is of the semi-floating type employing hypoid gears having teeth cut so
that the driving pinion meshes with the ring gear considerably below the center line of the
differential. This design provides quieter operation, increased gear tooth strength and a
lower car floor with minimum raised section for the propeller shaft. High grade alloy steel
is used throughout for gears and shafts and tapered adjustable roller bearings support the
differential assembly, drive pinion and the outer ends of the axle drive shafts.
As the axle bearings are accurately adjusted under load at the factory, no further at-
tention should be required. Special equipment is necessary to properly service this unit;
therefore, any adjustments or repairs required should be referred to your Authorized
Hudson Dealer.
The lubricant with which the axle is filled at the factory is especially suited for
