I have a 2003 Ranger FX4 172k miles. I replaced the driver side hub two weeks ago, everything went fine. Today. I replaced the passenger side hub. I put everything together, torqued the hub nut to spec, and went for a test drive. I'm getting this roaring from the front end. The best thing I can compare it to is like agressive tread tires. It's not noticable until I reach 45mph, peaks at 50, then decreases and it's barely noticeable at 60MPH. Anyone have an ideas what could be wrong?

 

I forgot to mention it does it no matter if I'm going straight or around a sharp corner.

 

Take it apart, clean it, look for hot spots. if its all good then try reassembly and test drive again. sounds like it got torqued a little bit too much. or the something is slipping when it shouldn't be. Usually hear it at the lower speeds more but it also can be in a specific range.

 

I had this noise when with my manual hubs on my 93 Ranger..which is different I know.. but it was because it was partially between locked and unlocked...

 

I took it apart, checked everything, and still does it. I'm not really sure how to describe this sound, it's more of a constant vibration, not a shaking vibration, but a solid one, I can feel it in the floorboard and in the steering wheel. When I replaced this side, I beat the hell out of the rotor trying to get it broke free. I plan on replacing them in a week or so anyway. Could I have damaged the rotor bad enough that it spinning is giving off a vibration?

 

what were you striking the rotor with? (at our shop we never his a rotor with anything than a rubber mallet) and if you brake does it vibrate more so then driving? maybe take that rotor off and bring it to a shop, they will usually spin it for free to tell you if its warped, and if it is, depending on how bad it is, i would just get it cut.

 

I was hitting it with a 5lb sledge haha... I know, not the right thing to use, but I have nothing else, and these rotors are original to the truck, and need replaced anyway, so no big deal. It does vibrate when I stop, but it's a totally different vibrate, when the brakes applied teh truck shakes side to side, has for awhile... without the brakes applied, it's a constant smooth vibration.

 

where did you buy the hub? i would bring it back and get a different one

 

Maybe it's not the good hub, and it make the rotor rub on the caliper bracket. Or a warped rotor. Can you hear it if you spin the wheel by hand with the truck on a jack??

 

well I would get new rotors first and see if it goes away, then if it doesn't then maybe it is a bad hub

anti-seize is your friend and coat that stuff so you don't have that problem again
