I put LS bell hammer grease on top of the grease that was originally in the bearing. I'm in good shape, but I don't think I can push it in firmly.

If the grease contained in the original bearing cannot be removed and the new LS Bell Hammer grease cannot be pushed in, apply the LS Bell Hammer series oil or spray to the original grease to restore the oil (including spray). You can bring out the effect of the bell hammer mixed with grease.
