Question about Toyota Highlander
I have a 2002 HIghlander. When the temperature is below 10 degrees there is a high whining noise from under the car as the car accelerates. It decreases as the car slows down. It does this whether it is in neutral or drive. When the warms up the sound usually goes away unless it stays very cold outside. Above 10 degrees this does not happen. Could you please tell me what this might be and if I should be concered. Thanks

I had the same problem at about the same mileage. Replaced the power steering pump and the start up screaming went away! ( The Jeep's and mine!)

Well, not sure if the temps have a direct cause for your problem, but you may want to check the CV joints on your axles. If you have ripped a boot, and lost the grease, that could cause a whinning. There are also a few other things it could be as well............any more info?

SOURCE: Whining Noise
Hi, this sound is most likely coming from the power steering pump. I would first, check the power steering fluid level to see if it is full. if its not at the full mark, add some fluid. If the fluid reservoir is full upon inspection and the whining continues, the pump may be damaged and the pulley on the power steering pump could be slightly out of sync with the pump housing.
The second issue could be belt slippage. i would do a tension check on the drive belt and pulleys as well. make sure there isn't any ware and tare on the belt and make sure the tension is to specs.
Please rate and god bless:)
