Thinking possibly it is a bearing that is shot.

Water pump possibly?

Take it to a garage that will assess the situation at no cost and will provide an estimate on repairing the problem.

Recently developed a whinning when I first start to move


Where is the whining noise actually coming from .. engine/gearbox or elsewhere?
A whining/screeching noise could be a drive belt .. such as the belt that drives the alternator.

On a manual car it could be the clutch bearing making the noise until it warms up. Does the clutch make a noise when you depress the pedal? That's the thrust bearing .. the bearing that operates the clutch.

I don't think you have too much to worry about. If you had engine trouble there would be knocks, rumbles and strange noises at all speeds.

A whining noise is usually associated with something spinning/turning .. such as a pulley/idler on a drive belt or a bearing alternator.

Put your mind at rest - get a mobile mechanic's opinion.

Have a 98 Olds Bravada it has a noise coming from rear of engine on the passenger side. Dealership said it was possible a transmission issue. I think differently, b/c the noise is at park or drive.


Depends on the noise. Tapping or knocking is rod bearings, engine side. Whining is the transmission side. Torque converter, pump, and parts further inside the transmission.

I have a 2002 chevy surburban and it makes a whining noise.


the noise happens running down the road or parked? Is the car a four wheel drive? The alteanator can go bad and whine, the wheel bearings can go bad and whine, windows not fitting right can make a whine The altenator will stop whining if it's unplugged, if this fixes it the battery and the altenater need tested and a bad battery can make the altenator whine and it still be OK. Don't run the engine with the battery disconnected as this can blow alot of expensive stuff and the altenator.

Whining engine noise


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

Same problem: a high pitch whine after extended driving


Sounds like a dry/failing bearing or power steering pump noise. You first need to try to track down where the noise is originating, and the most likely place is at the front of the engine.
I would start by listening with the hood up while parked with the engine running and the noise present, and seeing if it is coming from there. If so, the most likely cause is something connected to the belt - e.g. AC compressor clutch, tensioner, power steering pump, or generator. Can also be caused by the belt just slipping (warn out belt, tensioner not working properly).

"whining" coming from front of engine


With the vehicle running, take a long screwdriver and place the metal end on the alternator housing. Cup your hand around your ear and place on the handle of the screwdriver. Listen for strong whining noises. If nothing, repeat the same procedure for all components you can safely get to that is powered by your serpentine belt. Chances are, the whining is coming from worn bearings on a component such as an alternator, water pump, etc.

MPV 2001 burning smell, high whine?


Sound like the alternator bearings are seized or about to seize. The noise could be the bearings or the belt and the smell may be either of them also.
