Question: Squealing when steering wheel is turned all the way in either direction, tight steering after

2006 Chevrolet Impala SS 5.3L - 103,000 miles

When turning the steering wheel all the way or close to all the way in either direction while moving, I hear a loud squealing noise, and then immediately steering becomes hard, tight. After flooring the gas pedal and a few normal turns while on the gas, steering becomes relieved. Also, steering is normal when on the gas like that.

I have had the power steering pump, rack & pinion, and the return hose all replaced. Could this be an issue with the serpentine belt or something with the suspension?

I would try a new belt tensionar and serp belt. If theat does not work. I would make sure the ball joints are good and the strut towers are free. Jack the car jump and try to turn the wheel. If you feel resistance try to fond out what it is.

Hi Richard,

Thanks a lot for your response. The entire belt tensioner, not just the tensioner pulley, correct? Is there a way to check this before replacing? Mine is pretty expensive, even on rockauto.

When I jack up the car I notice that the wheel is much easier to turn. The tightness only comes in sometimes when I'm turning the wheel sharp and hearing that screeching noise, otherwise it's normal.

This morning it did it and it was very hard to steer all the way until a little bit ago I was making a hard right turn putting a lot of pressure on the wheel and hit the gas a little and now it's free, all back to normal. I'm just wondering what that may be. I will check the ball joints and strut towers tomorrow. Please let me know if there is a way to check the tensioner without removing. Thanks again!

Car Brakes: How Do You Know When to Change Them?

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
