I have a 2008 Class C Sunseeker on a Ford E-450 chassis. 15,000 miles
2 problems
1- After engine is warmed up, a harmonious pipe organ sound starts coming from under the front near the catalectic converter. Very annoying.
2- The rear dually brakes squeak very loudly during light and hard braking, basically any braking. Ford dealer says it’s from sitting. I told them we just went from Virginia to Topeka Kansas and back, they did it the whole way.
Any ideas?
