Overview

Tandem drive axles carry the load and the heat, and the wheel seal is the only thing standing between the hub oil and the brake linings. This Drive Axle Oil Seal from Automann is the Stemco Voyager type replacement for 38,000 and 46,000 lb tandem drive axles. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.

Tandem Drive Axles Sealed: The 393-0173 Wheel Seal Advantage

This seal is cut to the drive-axle envelope: 4.767 in on the shaft and 6.310 in in the bore, matching the Stemco Voyager type seal it replaces so the lip rides its original track instead of cutting a new groove into the spindle. The piloted entry allows a hand install, which keeps the seal square in the bore โ€” the single most common cause of a wheel seal that leaks again a month later.

At FleetPro Parts & Tires, we know the second wheel-off costs more than the first. This Automann seal is a direct replacement for highly searched industry numbers including Stemco 393-0173, Freightliner STM3930173 and CR 47691PRO. A leaking wheel seal can soak the brake linings, so replace it as soon as you find it. Inspect the spindle, the bearings and the hub bore while the wheel end is apart, and never put a seal back in once it has been driven out.
