2003 Monaco Coach Dynasty

GOODYEAR G670 RV TIRE: "RIVERING"- TYPE TREAD WEAR LEADS TO STEERING PULL AFTER LESS THAN 25,000 MILES OF USE. FRONT TIRES SHOWED RIVERING (WEAR BETWEEN 1ST AND SECOND TREADS) AFTER ABOUT 24,000 MILES. AS RIVERING BECAME MORE PRONOUNCED, THE STEERING PULL/DRIFT QUICKLY BECAME MORE PRONOUNCED. SWAPPING THE FRONT TIRES LEFT TO RIGHT CHANGED THE PULL TO THE OTHER SIDE. SUSPECTED TIRE DETERIORATION AND/OR INTERNAL BELT SHIFTING INTERNALLY AS CAUSE. I DECIDED IT WAS TOO DANGEROUS TO CONTINUE USE SO THE TIRES WERE REPLACED ALTHOUGH TREAD WEAR WAS MINIMAL. *TR

BRAKE CALIPER BOLT CAUSES TIRE DEFLATION THE BOLT (CAP SCREW) ON TOP OF THE FRONT LEFT CALIPER ON MY 2003 MONACO DYNASTY SLOWLY CAME LOOSE. AFTER BACKING OUT APPROX 1/4" - 3/8" IT STARTED TO SHAVE A NOTCH INTO THE TIRE VALVE. AT FIRST THERE WAS A SLOW LEAK (LESS THAN 1 PSI IN A DAY); AFTER A FEW WEEKS THIS INCREASED TO A 10 PSI LOSS IN ONE DAY; THERE WERE NO OTHER SYMPTOMS. PROBLEM WAS FOUND BY A LOCAL TIRE SHOP AND VALVE REPLACED. CAP SCREW EVIDENTLY IS THERE TO HOLD THE BRAKE PAD KEEPER SPRINGS IN PLACE. THIS DESIGN AFFORDS MINIMAL CLEARANCE TO TIRE VALVE STEM AND MAY EXIST ON OTHER MODELS WITH THE DANA (SPICER) FRONT AXLE/DISK BRAKE ASSEMBLY. IF PROBLEM HAD GONE FURTHER IT MIGHT HAVE LED TO RAPID TIRE DEFLATION AND POSSIBLE LOSS OF CONTROL OF VEHICLE. MONACO WAS INFORMED AND SENT PICTURES OF CALIPER AND VALVE. THEIR RESPONSE WAS THAT THIS WAS THE FIRST OCCURRENCE THEY HEARD OF, THAT IT WAS DUE TO IMPROPER TORQUE THE BOLT WHEN IT WAS ASSEMBLED. (VEHICLE WAS MANUFACTURED IN 2002). MONACO AND DANA SAID PROBLEM SHOULD NEVER HAPPEN AGAIN. I HAD FURTHER DISCUSSIONS WITH BOTH MONACO AND DANA ENGINEERING PERSONNEL AND OFFERED THEM OPPORTUNITY TO INSPECT VEHICLE. THEY DECLINED. *JB
