1. When I press on the brake pedal, after the car is at a complete stop and my foot is still on the brake pedal there is sometimes a very high pitch noise. It is for a short time. What could this be? also maybe related, when I turn the steering wheel for a very sharp turn the car makes a noise. What could that be? Thank you for your help.

Amy Mattinat, Owner and Author at Auto Craftsmen Ltd The steering wheel noise sounds like your steering pump - but this is just a guess. The brake noise - my guess would be the ABS pump.... BUT - no one can tell you what is wrong with your Jeep until they have it right in front of them and they can recreate the symptoms you described. I highly recommend you take it to your auto repair center and have your jeep checked over.

Amanda J. Pierce, MBA Marlene, The noise that you are hearing may be coming from an idler pulley, this is a pulley in your serpentine belt pattern, that is an additional guide. The bearing in this pulley can become worn and you can hear feedback under certain conditions. As for the noise you are hearing when you turn hard may be from the same cause, or a temporary excess load on the belt. Thank You for writing into AskPatty!

Barb Petrey, President - DBK Enterprises Inc at Jiffy Lube The brake noise is probably the ABS pump recharging. The other noise is the power steering pump saying don't turn me that far.

Lori Johnson, Owner and Instructor at Ladies Start Your Engines Dear Marlene, It's really hard to diagnose noises without having the vehicle to look at. It's possible that you have a belt noise. When was the last time you had the belts replaced? Check your owner's manual to find out recommended intervals. It's possible that when you're steering you're getting noise from the belt as well or you have a bad pulley. It's also possible that the noise is coming from low power steering fluid. I would recommend that you have a technician listen to the noises so that you can get a proper diagnosis. Go with the tech so that they are hearing the same noise you are. Lori Johnson
