Hi all I'm new to the site I have an 03 FX4 4.6 104,000 miles, Just the last few weeks I am hearing a squealing noise only when its a little warm out and after I have driven for maybe 10-15 miles it sounds like when you turn in a parking garage and your tires squeal. I had a guy tell me it was my tires they were cupped a little and I needed new ones so I replaced them but it still is doing it. I am wondering if it could be the wheel bearings or would being out of alignment cause this. It doesn't feel like I'm out of alignment but I'm not sure any help is appreciated thanks

 

have you checked ball joints? they are known for going out on our trucks and they produce a squeal when going over bumps and turning at slow speeds

 

I have not. I will check them thanks
