High pitch frequency/grinding when accelerating with my 2010 Dodge Journey
Hey everyone, I was wondering if anyone had any recommendations regarding the topic. When I accelerate my Journey I hear a high frequency/pitch sound, but it goes away when the car is not in motion. When I place it in neutral and accelerate you can really hear it. Any ideas on what this might be? I just had a new alternator and battery put in (within the last 4 months), and air filter (about 6 months ago). Just letting everyone know the recent service I had, other than the usual oil changes.
Did they replace either the serpentine belt or the belt
tensioning pulley assembly?
Hey there. No they did not. However, about 4 months ago I had this awful sound, and they determined it was the alternator (which I had replaced). The guy told me that the belt was worn and pulleys were as well...but they were functional, but I didn't hear any noises after they put in a new alternator. This high pitch/frequency noise just started. So you think it may just be the timing belt and pulley? I'm a novice with cars, so just want to make sure.
