HOW-TO:
Replacing the hub oil seal on Series Land
The most common reason for hub oil seal failure is a blocked axle breather, so check this first before you
start.
Remove the brass bell-shaped fitting on the top of the axle, and give it a shake. There is a ball bearing in
there, which will rattle if the breather is not completely blocked with dirt, if it does rattle, try blowing through
the breather, as sometimes the outer part can be blocked with dirt, even if the ball bearing rattles inside. It is
possible to clean them out with a bit of wire and some petrol, or WD40, though. It just needs a bit of pa-
tience!
Once it is clean, replace the breather back on the axle, and turn your attention to the hub that is leaking.
You can usually tell when the hub oil seal has failed, as oil will be leaking out of the brake drum, probably
onto the tyre on the inside of the wheel.
First remove the road-wheel and support the Landy on axle stands (do I need to remind you about that
still?? Squished folk don’t get driving Landies!).
Now remove the 6 bolts and spring washers holding the drive flange in place, and, if working on the rear
axle, then remove the drive flange and halfshaft complete. If you are working on the front axle, then you will
need to remove the ‘top hat’, or FWH if fitted (see article about swivel rebuilds… Here ) and undo the nut
and split-pin holding the halfshaft in place, before you can remove the drive flange.
This next photo shows the drive flange removed, it is a front axle, so the half shaft is still in place.
