hi huakenny, DanzEterna, D7zul,
yea, got it fixed. yes simple task to replace but needs lotsa prep work. the "spider" bearing didn't come out loose from the metal housing. the foreman had to shave off some metal from the inner housing in order for the "spider" to come out. other than this, i'm happy with the repair. so far, steering does not wobble. thanks for the advise.
thanks, going to get a wheels adjusted.
