Stationary shaft seal: the seal body stays fixed in its bore while the sealing lip rides against the rotating transfer case shaft, holding lubricant in and blocking dirt, moisture and debris.
Dual application: listed as both a transfer case input shaft seal and a transfer case output shaft seal.
Direct-fit replacement: made to install in place of the original seal on the listed applications.
Sold individually: this listing is for one seal; the per-application quantity is one.
Signs this seal may need replacing include transfer case fluid seepage or drips around the input or output shaft. If a leaking shaft seal is the cause, replacing it with 4333N restores a proper seal at that shaft — diagnose the source of any leak before ordering. Manufacturer part number 4333N.
