My truck is vibrating when I get to speeds around 50mph. Seems to go away at about 75mph. I just had my tires balanced and rotated and that did not fix the problem, although they said my tires had some "uneven wear". Anybody have any ideas?
Does it vibrate/thump like a wheel that is out of round or out of balance? Does it go away while turning (about a 1/4 turn of the steering wheel)? Did it just start recently after running fine for quite a while?
Check your wheel bearings. If it is the RF bearing, the vibration will go away while turning left. If it is the LF bearing, the vibration will go away while turning right.
I just went through this with mine. I had the tires balanced and rotated, and it got a little better, but didn't go away. The tire shop gave me the story about uneven wear being the problem, because they could not get one tire to road-force balance. Another place told me the problem was caused by the shocks needing replaced.
The problem slowly got worse, and the vibration and noise would get worse at higher speeds. I finally decided I should take it to the dealer and get it looked at. The night before, while I was out working, the bearing failed. I waited 3 hours for a tow truck, and 3 days to get my truck back. They replaced the RF bearing, rotor, caliper, mount, and brake pads (both sides). He said if I had driven any further, the front wheel would have come off.
All of this at only 33k miles. And I still had to go back today and pick up the lug nut they forgot to put back on the RF wheel.
Yes it feels like a wheel is out of round. I only start to feel it when the truck is up to speed at 40-45mph. I do not hear any noise, and I don't know that it vibrates when turning. I just had one of my wheel bearings replaced less than 10K miles ago.
I got my tires rotated about 2 weeks ago and starting noticing the vibration early this week, so I took it back in and had them balanced but not rotated. They said I had uneven wear on my front tires, which would have just came from the back since I just got them rotated. I wish I could swap tires with someone. I thought about that.
There's a chance it's the frame bearing vibration that has been described in a few other threads. Here's a link that covered it a while back, including a possible solution with Frederico rear sway bar. Hope this helps.
I had the same problem with mine. I took it to the dealer and they changed the carrier bearing. that helped then they noticed that the driveshaft allignment was a little out of whack. That helped. finally they replaced the front Drive Shaft.
My symptoms were a light vibration and a pronounced resonanting hum at speeds between about 62 - 66 mph only while accellerating or cruising it would stop doing it when I let off of the pedal.
Hope this helps
