I HAD THIS PROBLEM ON MY 2005 SAFARI CHEETAH. THE RIGHT SIDE CRACKED ALL THE WAY THRU AND THE LEFT SIDE WAS JUST BEGINNING TO CRACK. I CONTACTED MY DEALER AND HE KNEW NOTHING ON THIS. AFTER DOING SOME RESEARCH I DISCOVERED THE RECALL NOTICE THAT I DID NOT GET. MY DEALER COULD NOT EXPLAIN THIS TO ME, I HAD NOT MOVED SO IT COULD NOT HAVE BEEN AN ADDRESS PROBLEM.
ANYWAY I CONTACTED MONACO AND THEY SHIPPED THE 2 NEW ARMS OUT VERY QUICKLY AND EVEN PAID THE REPAIR SHOP DIRECTLY. VERY GOOD SERVICE!! ALL COVERED UNDER WARRANTY. VERY LUCKY THIS WAS BEFORE THE BANKRUPTCY. THE REPAIR SHOP OWNER WAS A FRIEND AND I HELPED HIM WITH THE REPAIRS.
FYI.. IF YOU REMOVE ONE SIDE AND TAKE IT TO A WELDING SHOP THEY CAN MAKE THESE ARMS. THE NEW ARMS ARE IDENTICAL TO THE OLD ARMS. THE ORIGINAL ARMS HAVE A SUPPORT BRACKET WELDED TO IT AND IN THIS PROCESS THE WELD WAS ALLOWED TO GET TO HOT AND WEAKENED THIS AREA AS PER MONACO. I THINK THE ARMS WOULD BE MUCH LESS THAN BUYING THEM FROM THE SUPPLIER. THE NEW ARMS WERE JUST THICKER METAL BUT SAME O.D. SIZE.
THE BRCKETS WERE NOT HARD TO REPLACE. THE RIGHT SIDE WAS MORE DIFFICULT BECAUSE THE REAR WHEEL/AXEL HAD TO BE PULLED BACK IN LINE. THIS WAS ACCOMPLISHED USING A CHAIN WRAPPED AROUND THE AXEL AND THEN PULLED WITH A TRUCK HITCH. ALL YOU NEED TOOL WISE IS AN AIR WRENCH. HOPE THIS WAS HELPFUL.
