What is making this 08 caliber 2.0L sxt cvt have a High pitched whining sound at idle and driving?


Possible bearing in one of the drive pulleys. I have changed numerous alternators for this noise. Take the belt off and start the car. If the noise goes away you know it will be pulley related and not transmission related. If noise goes away, spin all pulleys by hand to determine the defective/noisy one

2002 Chevy Trail Blazer. Loud pop sometimes in rear when turning. Noticed sway bar is loose, bushings worn out . Could that make the pop noise or is problem possibl worse?


sway bar bushing could be problem. I would replace it before trying anything else and yes that will cause it to pop from time to time. In some cases if not replaced in time the bar itself could break

High pitched noise at highway speed


I also have a 2005 Tucson. It makes a loud whistling noise when approaching 75 mph. It comes from teh top of the windshield. I had the windshield replaced and thought it would solve my problem, but no. I should have had it fixed when warranty was in effect but I don't drive that fast much. I also need hlep.

Starter makes whinning noise on 97 camarro .battery is fully charged and starter tested positive at parts store.


Make sure that starter wears a condom.

If you meant that the starter makes a high-pitched whine but does not turn the engine, that starter is bad. More specifically, its drive (the "Bendix") is bad.

If the starter makes a screeching noise as it turns the engine, like it is working too hard and is irritated about the situation, you need to shim the starter. There are shims available at the parts store that fit around the mounting bolts, between the starter and the block. They are used to ensure that the starter drive gear teeth are not too close to the ring gear. If they are too close, the starter has to work much harder as it forces the teeth to mesh.

If you meant that the starter makes a whining noise for a short while after you start the engine, don't worry. Many starters do that.

If you meant that the starter makes a loud whine constantly after you have started the engine, it is staying engaged. It is either bad and that is the source of the problem, or there is another problem (like incorrect shimming) that caused it to stay engaged, and it is now bad. The same gear reduction that allows a small electric motor to spin a big heavy engine can work in reverse if the one-way clutch in the starter drive goes bad, and the high speeds that the starter guts would be subjected to if this happened would lead to self-destruction.

2002 trail blazer - front left "drive-shaft"? sounds and feels like a bad bearing. What may be the problem/solution?


a few things to check and try to help determine if its bearing . the good ole annoying " growl" that gets progressively worse as speed increases. does the noise change when making turns... try swerving the blazer side to side. if it changes...u have a bad hub assembly . as a rule a drive axle wont do more then vibrate or click on a turn, especially that year with the constant velocity joints in the front. hope this helped you out

Continuous "whine" @ 1500 RPM only; and jerks/2001 Lincoln LS


Run the car from the top of a hill and let it coast at your whining speed. Put it in Neutral, does the whine disappear?
If not its in the drivetrain (wheels, driveshafts, tranny)
Very unlikely to be the timing belt. If it appears at a fixed speed then its drivetrain, if it whines at fixed revs its the engine.
Most likey the transmission I fear....Tires will also make loud whining noise too though...
