Leaking Seal

Hi guys
Whilst doing some maintenance I discovered a small oil leak. Does anyone know what this seal is called.the front drive shaft comes from this point forward.
Thanks in advance

Hi Steve.... If you said the transfercase front driveshaft/output shaft seal they should know what you're talking about. I had one leak a while ago and replaced the seal but it still wept. So then had to get a Speedy sleeve fitted as the shaft was a little grooved but it wasn't that obvious. Just saying to have a good look at it while it's out.

Regards John


I didn't have a speedy sleeve so replaced the flange bit that the universal bolts to which fits on the splined output shaft. I think that came from Don Kyatt also. The centre nut is a bit special. 36mm castellated and flanged (on FG649). Broke a breaker bar trying to undo it. Neighbour's rattle gun worked. The nuts/bolts for the flange cost arm and leg, I used Nylok - deeper than original but there was enough room.

Cause of my failure was possibly the very worn splines in the drive shaft. I could feel the vibration. If not the cause it contributed. Had it rebuilt (and lengthened a bit to compensate for spring height) by Hardy-Spicer in Darra.
