It includes: a table of contents that lists 1) a cover letter to the dealers explaining the nature of the recall and the upgrade campaigns that went above and beyond the recall. 2)It contains sample copies of the Dealer Notification and Owner Notification letters and the Canadian equivalents (2013-035 and 2013-036). 3)A complete list of units covered and the recalland upgrades they would need. It also includes the Recall Repair Documents RD-00031 rev C and RD-00040. TheRD-00031 repair addresses the lateral stability of the bottom rail in the immediate area forward of the landing gear and front hopper. Lateral movement in this area allows the bottom rail and steel internal structure to flex side to side between the two crossmembers forward of the hopper. Excessive flexing can cause fatigue cracks and fastener failure. RD-00040 addresses the fore and aft stability of the suspension subframe that has caused cracking in early versions of the front attachments that connect the front of the subframe channels to the aft hopper crossmember. The repair is to remove the first and second versions of the front attachment and replace with the third version with additional reinforcements. The additional campaign proceedures were the RD-00037 rev A, RD-00032, RD-00035 rev B and RD-00041. The nature of the first three are covered in the 14-Nov summary. The RD-00041 upgrade addresses the lateral stability of the aluminum subframe aft of the suspension hangers. Lateral movement in this area allows the subframe channel to flex side to side between the hanger and the suspension air bag. Excessive flexing can cause fatigue cracks in the aluminum channel. This covers the 2009 through 2013 model years.
