TEMPORARILY OUT OF STOCK; AWAITING SHIPMENT OF 100 MORE AXLES. PLEASE INQUIRE.
The axle shafts are without a doubt the weakest part of the TD/TF differential. While he factory shafts look beefy and thick, these characteristics actually make them rigid and inflexible, and very prone to failure. When this happens, the axles twist off a 2" stub deep inside the differential - without any warning at all - (see photo) and considerable effort is necessary to remove the broken bits to get the car back on the road. With one broken axle shaft the car cannot be made to move.
My new and improved axles (originally known as Jerry Austin, and later as Dave Clark axles) are engineered with a slight taper and reduction in diameter, which gives the axles a significant degree of spring and twist to prevent breakage. They are manufactured from the finest 1541 steel with a Rockwell hardness of 62, which penetrates about 1/3 of the diameter of the axles - far more than the originals (the surface hardness of the original axles is perhaps 50-55). In the "old" days, T-series drivers would need to carry a spare axle shaft and bearing when touring - and many were put to use. This is no longer the case - more than 2,000 of our re-designed and improved axles have been sold, and there has been not a SINGLE reported
