Hubstack troubleshooting

My lil bro got a new grind machine less than a week ago and a day or two of playing it has surfaced a problem with one of the stacks… It spins about as well as trying to sled up a hill… To give an idea, no matter how tight ya hold
The stacks, you only get about 4 or 5 seconds of sleep before it dies… What can I do to make it work the way it should?

The bearing the hubstack is using may not be working. Repair or replace it.

Look (using the search button here) for “how to clean a bearing”. EDIT: o hey, the modding section has a sticky about it…

I don’t like cleaning bearings, so I give hubstack bearings an extra drop or two of thin lube. They spin a bit slower, but it’s not so bad.
