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
Normally this is a tire out of balance. Have your tires rotated an balanced.
it needs to be balanced
I would suspect you have a broken motor mount. If that is not the case, then you need to inspect all suspension parts, and the drive shaft universal joints.
Tires or wheels out of balance?
Out of balance wheel, damaged or faulty tire, bent or worn axle.
There are a number of things that I know of that can cause this one. First off did you have an alignment done after replacing the tires? I would also suggest checking out your front end ie ball joints, tie rod ends, wheel bearings and so on. Good luck
Yes, it can
The wheel will be stuck or will shake the engine. if you put the spacer that attaches to the CV joint on back wards it will be hard to turn. there is a wrong way and right way to put that spacer on. I put mine on backwards and the wheel did not even turn. try cleaning it out with mineral spirits then regressing it and put back together.
Your front end is probably out of alignment. Have it checked at a mechanic.
I was told by a buddy of mine who's a GM Master Tech that it's the Universal Joint in the axle. He said I'm better off just replacing the axle with a reman for a few dollars more.
try the steering stabilzer
It is supposed to rattle when you shake it. if it does not, it needs replacing. The rattle you hear is the check valve.
