Hey guys,

I've been having an issue with my truck vibrating above 60 mph. The truck has brand new tires and they were balanced when they were mounted. Along with that it feels like my brakes have been rubbing a bit which is weird since I just had new front rotors installed and the rear rotors shaved. I'm looking for some ideas as to what the vibration can be (wheel bearing, drive shaft, etc?) and what the rubbing could be. Is it possible the people who did the brake job might have done it improperly causing some rubbing? Brake job was done in May and there has been some rubbing ever since at low speeds but it's not a constant rubbing. Nothing feels to be "dragging", just rubbing. It might not even be the brakes... Anyways, I am just looking for some more ideas as to what it could be because there are a few things I can fix myself but then there's things that my warranty can cover such as suspension and wheel bearings. Thanks guys!

 

Well these are floating brakes, Fords usually had this problem, when applingthe brakes the pins in the calipers would freeze (for lack of a better term)But that would end up with uneven pad wear. You could check for even wear, I would inspect with the pads off the calipers. and measure, they should be even. The rubbing issue will undoubtedly be a warped rotor. You can only resurface once at the most. Semi metallic pads actually wear down rotors. when in the past they only needed to be turned. not so these days. After 50.000 miles, mine were replaced, not shaved as you put it. Replace rotors and pads again. always start fresh with brakes. i would not take chances especially if you have young ones to tote around. Good luck. most midas shops do a free inspection btw. and will tell you the same thing. well they oughta imo.

 

The rubbing started after having the front rotors replaced in May and the rear rotors shaved. The pads still have a lot of life left on them. I'll take the wheels off this weekend and give them a close up inspection. Now as far as the vibration goes, other than the tires being re-balanced what else can I do? Anything I can do to check for a bad wheel bearing? I'm open to any suggestions.

 

jack up the front grab the edge of the tire and wiggle. If you feel a lot of play chances are it's time for new front hubs. I just replaced mine and let me tell you bud be glad you have a warranty cause they were a son of a .... to get off.

 

I'm hoping it's not a bearing and just something easy like brake pads or having the rotors turned. The problem is finding time to get out in town to have my truck looked at unless the place on base deals with warranty companies.

 

ya trust me we have been dealing with issues with the Hummer. It's a pain in the butt to try to get off in time to make it to any of the places before they close.

 

Just noticed the two wheel drive. You may have a loose tie rod Or ar more realistically a blown socket in the tie rod. As you drive the tie rod has pressure put on it . as it wears. (and they do.) The tie rod nd starts too oscilate. (rock back and forth.) You will have failure if not adressed. bearings when worn usually won.t vibarte imo. they wear and heat up. Then fail. Both failures are catastrophic btw. Inspect every thing in your front end.

 

Lift the front off the ground, and do like he said earlier. Pull in/push away around the tires. See if you have any give?

Mine does this in turns, but you didnt say anything about that so I dunno

 

It's not unheard of that one of the newly installed wheel weights that they used to balance the tires may have fallen off. Or, it could also be that they forgot to balance one of the wheels. These things occasionally happen.

Wouldn't help with the rubbing, but it would explain the vibration.

 

since it started when you had your brakes done, my bet would be something brake related.
if you have a micrometer or a digital micrometer, measure 8 different spots all the way around each of your rotors. see if they are out of parallel.
if they are way out of parallel it will cause a vibration that you will feel on and off the brakes
