Tail-wheel Lubricatin?

[MNForrest]

So, I just replaced the wheel in my Haigh tail-wheel. The "Homebuilders Special" 4" wheel I picked up from AS seems rugged and nice and round. The bearings, however, roll well but not as smooth as the ones I just removed. They're even a little noisy. Do I need to get in there and grease them up? Is there a better bearing I should be using?
Thanks,
Forrest
