I recently rebuilt the 1FZFE engine in my LC and had this starter screech both before and after the rebuild. The vehicle sat for a year before I pulled the engine and assumed that a new starter would correct the issue. I replaced the original with two reman starters and more recently a brand new High Output 2.2KW starter. The flex plate and gear teeth are in nice shape. Not sure if shimming the starter is a need on Land Cruisers. Have a listen to the video and let me know your thoughts.
