l have a 2001 nissan altima. It squeaks when l drive, it sounds like it is coming from the front tires.l did not know if this could be my hubcaps???l have never had any problems with the car.The only thing that l have done is brakes and new tires.Any ideas on what this could be and how much to fix it???Thanks!!!!!
Only happens when l am driving...when l stop the sound stops.Brakes have been replaced about a month ago, but this problem occured long before that.

air in tires

when you drive or when youre stopping?

it sounds like bad brake pads, thats not too expensive unless it gets so bad that you grind the rotors which are expensive

could be your brakes,axels,or shocks
i doubt it will cost much

It could be your brakes pads touching your rotors, or needs front end lube.

ill give you 2 options, it will be 1 of those 2
bad struts or k-frame body mounts

it could either be your breaks (depends on if they where put on right or if you had had them on a while) Possibly your rotor has a rock in it. Or maby a barren in your wheel might be going out. l would have it looked at by a Nissan certifed mechanic. l dont think any of thoes things are that expsensive, but if you dont have it fixed it will cost you alot more... good luck :)

It depends how old your brakes are. If they are fairly new, and a skilled technician installed them, then its not the brakes. My guess would be hub bearings or wheel bearings, because they make a screeching noise when the wheel is turning.

It is not cheap to replace hub bearings, but it is better than having your wheel lock up, or having other parts suffer damage because of it.

nissans have what is called a backing plate which is behind the rotor. the metal is thin. it is very common when during a brake job that it gets bent a little inward and is just touching the rotor. everytime you move it has a high squeel to it. the backing plate prob needs to be bent back a little. this can be done with a flat tip screwdriver.

l think you have already guessed it. These cars had hubcap issues. They tend to squeak over time. Just take the hubcaps off and drive it to see if that fixes it. Pretty sure it is not the brakes because you said it happened before you had the brakes done.
