I have 2 strange noises coming from my 2002 EVC.? The first noise is a low grating noise that appears to be coming from the right rear.? I initially thought it was wheel bearing related, but my mechanic found no wheel bearing issues.? The noise is most apparent when first driving the van after it has been parked for a while with the emergency brake applied but is noticeable while driving.? The right rear wheel turns silently and freely by hand.
The second noise is a low rumbling while driving at speed (65 to 70 mph) with a frequency of about 2 cycles per second.? The noise appears to come from the rear of the van, but it is difficult to determine the actual location while driving.
Neither of these noises appears to affect the operation of the van or appears to be engine/transmission related.? The rumbling noise frequency is not consistent with the wheel rotation frequency and there are no moving parts back there except the wheels.? I am stumped and would appreciate any recommendations or observations.
