Question about 2006 GMC Envoy
There is a whining engine noise ans as i accelerate the noise gets louder
If the noise increases when idling and reving up the engine then you must check on the engine pulley, the belt idler pulley, the water pump , alternator or the a/c. But if the noise increases when you are moving then you must check on the wheel bearings, the drive shafts and the inspection of the mudguards for tyre rubbing. If so you will have to jack up the car and check for faulty bearings, drives or tyres. SInce the noise can be traced to the point of generation , you will have to have a friend also to check on one side for pinpointing the sound and identifying the part. This must be easier to find and you can easily replace/repair/change the part concerned. Hope you try. Good day
