Around the November 2017 time frame there was some suspect RH 2010 arms that were found to have a slightly larger hub which could cause the arm (hub portion) to slightly rub on the 2010 finish plate. This was only on the RH arm, LH arms were not effected. If customer encounters this issue replacing arm will resolve the problem.
Quality inspected all parts on Production Floor and in SOMI and pulled all suspect parts. Quality also put corrective actions in place with supplier to prevent any future such issues.
