I had my truck in for service yesterday to get the vibration problem looked into. I ambushed the service manager in the parking lot as he was coming in for work and he spent over an hour with me driving and talking about my problems. I've been experience the typical mystery vibe that many are. Mine's not severe, just a bit annoying. Any way, to the point.....

He performed a "Road Force Test' on my tires and the result was a slight improvement at highway speeds. Three of my BFG's were slightly out of balance. It didn't completely solve the problem as it still feels a little busy through the floorboards and pedals at lower speeds. I've only driven about 10 miles since then, so I'll wait to pass full judgement.

I also requested a tire rotation with my truck right at 6000 miles. I come to find out, however, that when you RFT the tires, the computer tells the tech which tire goes where. Meaning, I get my truck back and they've scrambled up all my tires! One of the original fronts is still on the front, it just on the other side. The other front is now on the opposite side rear. Service manager claims that those are the "optimum" locations according to the cumputer analysis. I was under the impression that changing the direction of a tires rotation wasn't "optimum". Also, now one of my fronts in doing double duty as it's still on the front. And, it's turning the other way!

Any opinions? I don't know what to make of this.

 

If its a radial tire it doesnt matter which way it turns. That only applies to bias ply tires.

 

Some radials have directional tread patterns. The side of the tire would have a little arrow to indicate rotation direction.

 

our trucks do not have directional tires i believe, so the can go either way.

 

Like all of you guys, I'm reading all these posts here lately concerning a vibration. It seems some people have it while others dont. Also seems that most are experiancing it after X number of miles. I've heard before that BF Goodrich tires have a tendency to get "hard" after a while. I suppose that means the rubber stiffens up??

What I'm wondering is for those of you that are having the mysterious vibe, what type of tires do you have? I might be mentioning something that's already been discussed, if so sorry for the repeat!

 

A major problem in reviewing the threads re: vibrations is:WHICH vibration? Vibration A, Vibration B, Vibration C, etc. ? This is getting to be like comparing donkeys with camels. We now have vibrations, buzzes, shakes, shimmeys, bounces, rattles, trembles, shudders, oscillations, chatters, and resonances. I'm getting as confused as the service managers.

All I know is that mine quit when I put it in neutral! Others report that the vibrations stop when the truck is sitting in the garage with the ignition off. Go figure.

 

My truck has been in the shop since last Monday (3/2) for the vibration and steering wheel shimmy and is waiting for a rear axel and rotors. Seems the rotors are attached to the axel? Does this sound right?
