X2!!29. i use non-clorene brake cleaner and flush bearing every race! bearing sheilds help easy on easy off allow to dry and lube w/ your favorite lube! jmo.
Grease seals can be removed for cleaning, and reinstalled.I use W-D 40 to wash out the bearings ( won't work on sealed bearing ) Then use TRI-FLOW, works great for average cleaning. I think that baking the bearings in an oven, then dropping in TRI-FLOW will put the lube in back in the pores in the metal. Just my opinion, Hey, it worked good on my super minicup car
