Found metal fragments in the filter of my Samsung Front-Load washing machine (3-yrs old). This was after I noticed that the basket was unbalanced during spin and would spin-up and spin-down endlessly. Followed procedure from 2-videos (replace Assy Flange Shaft; replace rear tub seal). Performed repair, and the machine works as well as it did when it was new. Used the opportunity to replace the rear tub seal and Tub Seal. Also, cleaned the inner and outer tubs. After having to completely disassemble and reassemble my washing machine, I get great personal satisfaction and confidence knowing that I ordered the correct parts and completed the job, and saved a lot of money! You folks are AWESOME!!
