  "excerpt": "Mack Rs, Wl, Ws, Rl, R, Mb. Published by Transport Canada as 1977111 on 2 December 1977. System: Not Entered. What the notice says Vehicles equipped with swtl56, sw56 or sw57 series bogies (tandem axles). the welds securing the rear axle spring insulator bracket to the axle housing are improperly positioned and could break causing the axle to move out of position resulting in a loss of vehicle control. Is your vehicle included? Check with your VIN at Transport Canada , or ask a dealer. This page is an independent copy of the notice, kept so you can see what changed after it was published. It is not the authority, and the authority’s own text is the one to act on. This site holds seven national and European registers. Mack RS is named on 16 American notices. Those are separate campaigns, filed with separate authorities on their own schedules. Recall 11V272 - Mack trucks is recalling certain model year 2011-2012 chu... Mack Trucks recall 10V537 - Model Year 2011 Chu and Cxu, Heavy Trucks Manufactured Fro... Mack Trucks recall 10V536 - Model Year 2010 Through 2011 Cxu, Heavy Trucks Manufacture... Nothing here says any of these is this notice in another country. A model recalled in one country is often recalled in another, in different words and at a different time, and the authorities do not cross-reference each other. Reading them together is the reason this site holds more than one register. VEHICLES EQUIPPED WITH SWTL56, SW56 OR SW57 SERIES BOGIES (TANDEM AXLES). THE WELDS SE",
