Last time I replaced one it appeared identical to what I removed.
I removed the old one by packing it with grease and taping in alignment
tool( a section of input shaft from a failed 4KQ trans). Pressure
achieved this way forced the bearing out. If you place in one with closed
back how can it ever be removed again?
