I can't seem to find loose 3mm balls, any ideas? I need to repack a linear
truck.

That's about gerbil size, isn't it? You could raise some. They breed really
fast.

If you're talking about an THK/IKO sort of linear bearing, those are
often selective assemblies. Graded balls are used to set the preload
and accomodate manufacturing variation in the rail and car.

Make sure the balls don't alternate in size. Sometimes you have a
big/little/big/little/... arrangement.

If it's a really low-tolerance situation, bicycle shops
should have 1/8" BBs in stock... grade 200, usually
a couple bucks per hundred, maybe twice that
for chrome steel grade 25.
