It can be nigh impossible to get a puller on the pitman arm, but if you
can get the bolts out you can turn the box out 90deg and get to it from
the 'side.'Â I sacrificed a cheap, long slotted screwdriver and bent the
very tip to improvise a puller. I ground the tips of couple eighth-inch
dia. steel rods to make a long, flat blades to tap the new seal in. Â
It's a bear, but it can be done.
I agree with Michael on (not) using grease.

It can be nigh impossible to get a puller on the pitman arm, but if
you can get the bolts out you can turn the box out 90deg and get to
it from the 'side.'Â I sacrificed a cheap, long slotted screwdriver
and bent the very tip to improvise a puller. I ground the tips of
couple eighth-inch dia. steel rods to make a long, flat blades to
tap the new seal in.  It's a bear, but it can be done.<br>

<div>My BJ8 steering box is leaking. From the front cover
and more significantly from the shaft.<br>
</div>
<div><br>
</div>
<div>Firstly, is it possible to replace the shaft oil seal
without removing the box ? - that is not going to happen
at the moment.<br>
</div>
<div>Looks sort of feasible to me and possibly the most
difficult issue would be extracting the old seal ?<br>
</div>
<div><br>
</div>
<div>Secondly as often mentioned here is to refill the box
with some Penrite or similar NGLI 00 liquid grease. Is
there a sensible/practical tecnique to get it into the
filler hole ?. Grease gun with plastic tube ? Sounds messy
job to me.<br>
