I needed some new seals, and the kit with the bearing was not much more, so I decided to overhaul my D60 spindles. I would imagine a d44 is similar.
Special tools needed:
Slide hammer
Press
Strip down your outer and remove your spindle
Spindle and the new kit. It includes the two seals and one bearing
Set spindle in vise and use a slide hammer to pull the old bearing out
(it has hard to do this and take a picture)
Press in the new bearing until it bottoms out. Arbor press worked fine, it could even be tapped in with a hammer
Install seals onto the axleshaft and in spindle (as shown). Lubricate bearing with some axle grease.
Reinstall and you're done!
