You could have a problem with the CV joints, brake rotors, bent rims and yes, even a slipped belt on NEW tires. If you have the ability to do so, jack up the front end, put the vehile on jack stands so that none of the drive wheels will turn, then watch the front wheels while someone else gets behind the wheel and runs it up to the speed where you have the vibration. You can also watch the tire/wheel at lower speed to see what is moving in ways that it shouldn't.
Your vibration can be from a lot of sources. Tires, balanced? Checked them for a separation/out of round. Tie rod ends, stabilizer, ball joints? Even a torn motor mount can cause a vibration. A warped rotor can cause a vibration when the high spot passes through the caliper. You have a lot of things to check out. Good luck
check drive shaft run out and drive shaft balance NEW ANSWER: You need to check the driveshaft U-JOINTS for wear. If you don't find your problem there, Then you may have to get the wheels balanced. Check U-Joints FIRST.
Try the changing the Tie Rod
is your truck 4 wheel drive, if so have your universal joints checked, also have your front end parts checked(tie-rods etc.) if it is not have the balance checked on the front tires, in both cases, sometimes when you get in mud, mud will build up inside of rims and cause balance to be out. if all these are ruled out, have the tires checked for a broken belt
Drive shafts are balanced to prevent vibration, if yours is doing it you need to check your universal joints, and whether the shaft has been dented or if one of the weights used to balance it has fallen off.
The universal joints are worn out.
This could be caused by bad u-joints.
Correctly phasing the u joints will prevent driveling vibration Doing it incorrectly can cause a damaging vibration that can ruin, transmission, transfer case, differential etc.
Expansion Joints are installed in the piping system to absorb vibration and shock. They also have the Advantage of reducing noise and compensating caused by misalignment.
The transmission is usually pretty vibration free. Check the CV joints. Hopefully it is not the flywheel.
The Pacinian corpuscles contain mechanoreceptors that detect vibration. These receptors are found in the skin, joints, and other connective tissues of the body, and they are sensitive to changes in pressure and vibration. When a vibration is detected, the Pacinian corpuscles generate neural signals that are sent to the brain for processing.
Have you had your u-joints checked?
