RPM & Robinson Racing make bearing "Blasters" that hold 1 bearing inside so you can spray out with cleaner and relube.
They work like a full size bearing packer and "SEAL" the bearing in a cone like device so the cleaner will be forced past the shields/seals. They work really well and much less work than removing the seals/shields.
An Ultrasonic cleaner would probally be the best. You could do all of the bearings at once and leave it unattended to go work on something else while they are cleaning. (I like that idea)
OK, now for my question.
Who makes a REAL Ultrasonic cleaner for a decent price and will allow you to use solvent based cleaners inside. (not water based only)
I use the RPM bearing blaster and works great for me, but contrary to popsracer said, I think it is needed to take the seals off to allow the debris get out, don't you think?
