I just replaced the entire blade-brake side spindle including bearings and shaft on my TroyBilt 33" wide-cut due to a failed bearing. When engaging the blade, it was noiser than ever so I removed the spindle and manually greased it (no grease fittings). I also made sure everything was properly aligned when I re-assembled it. It is still VERY noisy. Is it possible that the brand new bearings are bad or is there something I am missing?
