I have a strange problem with a squeaking/rubbing noise coming from the front end. Not sure which side. I say strange because the problem does not seem to have any rhyme or reason to it.


When I start driving, everything is fine. It is only after I drive around two to three miles that the squeaking or rubbing begins. It only rubs when the car is in motion. It usually starts after a few miles and when I make a left turn. But sometimes it can start on a right turn but not as often. In fact, making a right turn can sometimes make the sound go away while it is turning. After completing the turn, sometimes the sound comes back right away, sometimes it stops for a minute or so and then resumes.

At first I thought it may be the break warning that the pads are warn. However, breaking does not change the sound, stop the sound or start the sound. I would assume if it was warn pads, the sound would change or start/stop depending on breaking. Also, I looked at the pads when replacing the summer tires and their was plenty of pad left and I do not drive often.

I then thought, maybe a bad bearing but again, I would assume a bad bearing would make noise all the time and get worse or less noisy when shifting weight from turning but not stopping altogether or taking three miles to start making the sound.

So then I think, maybe it is the power steering. But again, it only does it while the car is moving. I can turn the wheel all day long while idling and no sound. Same for a loose belt, I would assume it would make the sound all the time, not just when the car is moving.

I am not rich, hence the reason I drive an ancient car so, I cannot afford a couple of hundred dollars just to find out what is wrong with it and be told it is something more expensive than the car is worth. I have no idea where to even begin to try and diagnose what exactly is making the noise to fix it myself. It does not seem to fit any of the more obvious scenarios. Any insight would be greatly appreciated.

Good afternoon.

The first thing that comes to mind is the backing plate on the front rotors. Remove the wheel and inspect the plate and make sure there is enough clearance between the rotor and the plate. It is a common reason for this noise.

Yes, I had thought of that but figured if that was the problem, it would be a constant noise from the moment I start driving. The thing that is throwing me off is that it takes several miles of driving before the sound starts and it usually also requires a turn after the several miles for it to do it. Since the plate is directly behind the rotor, I figured if it was bent and making contact, it would be a constant sound as soon as I start driving and would not go away as the back plate is always lined up with the rotor whether going straight or turning. I will take a closer look at it but I cannot get the tires off until tomorrow. It would be nice if it was something as simple as that.

So after three days of rain I was finally able to look closer at the vehicle. I can find no problems with the back plate or brakes. I definitely think it is a power steering problem. When I crank the wheel to the left, the squealing starts. It continues until I brake and come to a stop then the sound goes away. I turn the wheel far to the left and it starts again.

The thing is, I have no fluid under the car where I keep it parked. The fluid in the reservoir is not foamy so, I do not think there is any air getting in it. There was fluid leaking out of the reservoir cap but I think that is because I filled it too high to see if it would make the noise stop. As far as I know the cap is not necessarily air tight so I assume it is normal for fluid to leak out in the event of an overfill. I removed some of the fluid back to the proper level and drove it in a circle and there was a bit more fluid on the reservoir again.

The sound does not seem to change with the speed of the vehicle as far as I can tell and it's mostly when I turn to the left. It is weird that I cannot produce the sound when the car is idling no matter how much I crank the wheel. It is also weird that the sound will start when I turn left, continue to make the sound when the wheel is straight, stop making the sound when I come to a stop and not make the sound again until I make a left turn. I have no idea if it is a bad pump, a bad hose somewhere or if the rack and pinion is shot for that matter. Not sure where to go from here?

Check the rack mounts for the steering rack. Make sure the bolts are good and tight. Also check the rubber in the mounts for cracking. They could cause that issue was well.

As far as I can tell I cannot see anything obvious. I also just had a lot of the front suspension fixed/replaced, sway bar, control arms etc, and an alignment a few months ago and they never noticed anything during the inspection. Starting to wonder if any repair is going to cost more than the car is worth. Just getting it diagnosed costs a fortune here.

One thing I have just noticed is that the wheel is not returning fully to center after a turn. It returns a good 95% of the way or so but I have to turn it that extra inch or two to get it to center. So I am wondering now if maybe it is a rack problem since I just had a front end alignment done several months ago.

Could be. I would have the rack bushings inspected closely to see if the rack is moving inside the bushings.

Yes, I guess it is time to take it in. Ugh. I will make an appointment and see what they find.

Thanks.
