vibration and front end noise

[Chamberlain79]

I have a 2001 4x4 crew cab. I bought it about 3 weeks ago it vibrates hard from 35 mph to 45 mph and has a slight vibration from 45 on. Ii also makes a roaring noise sometimes not all the time. I beleive it may be a wheel bearing I tore the front end down to the wheel bearings and they felt good. Its the one in the avitar any suggestions thanks.

You would get a better feel for the wheel bearing without even taking a wheel off...just distinguish what exactly the up-down movement is when shaking at 12 and 6 o'clock on the jacked up wheel (could also be ball joints) but if you have a roaring noise it's almost certainly a bearing...that won't really cause a shake though. Your tires could be out of round or just need balanced.

my rear tires are out of round pretty bad and I notice it about the same speed.

I had the tires balanced and rotated yesterday and it still vibrates. But not as bad I checked the wheel bearing with the tire on and off . All ball joints,pitman arm,tie rod ends are new. I think it is a tire because it still vibrates now but not as bad and they put 14 ounces or weight on one wheel. I guess new tires are next.

Check your driveshaft trust me.

[Chamberlain79]

What do you mean check the drive shaft ? i have checked it for bad u-joints and replaced the carrier bearing. How do i check it it doesnt have any visual defects that i can see. Thanks for the info.

[Tony V]

Well If you get under your truck and wiggle the shaft does it move or is it tight?

[Tony V]

If its not that I have the same problem I am trying to figure out actually. Is the vibrations by your feet?

[Chamberlain79]

The vibration is in the whole truck but the noise sounds like it is coming from under my feet. I am going to check the driver front leaf spring to see if the rear bushings were wore out. The drive shaft is tight. The bushings shouldnt cause it to vibrate i wouldnt think .

[Tony V]

No they wouldn't. See I have the same problem you are having and I cant figure it out. I have already changed the left wheel bearing and it did'nt fix it so I am going to change the other just to see. I have no idea what it is.
