Spindle wear?

[Nostalgic]

Looks good from what I can see.

Here's a pic of my worn spindle that needs to be replaced -



On the right in the pic you can see the step (wear is on the bottom surface). It's right at the limit of being usable, but it DOES wear the insides of the tires.

As far as your bearings, the only way to really check is to measure the OD of the spindle, and the ID of the bearing. I couldn't tell you what the spec is, just that mine have .008" of slop due to the worn spindle. I would guess that .001-.003 would be good.
