In "Model T Ford in Speed and Sport" I saw the following on page 42: "To remove the drive shaft unit without taking off the rear axle, proceed as follows: Remove the 6 drive shaft roller bearing housing cap screws. Remove two cap screws and two bolts which hold the ball cap to the flange of the transmission case. Take the front nuts off the rear radius rods. Then, by twisting the driveshaft housing, the ends of the rear radius rods will be pulled out. Pull the rear radius rods down towards the ground - and the drive shaft will come out."
Has anyone tried this and does it work?
It will work depending on the gear ratio. Some pinion gears are larger than the hole and at least one side of the axle housing must be removed. Also, if you are planning to replace any parts such as the driveshaft itself or the bearing or the front driveshaft bushing, the gear clearance should be checked upon reassembly. Because any change in those areas (even a gasket) can change the gear lash.
