I have a 2001 Mazda Protege DX with 102,000 miles. I am getting a lot of vibration in the front end when going over 60 mph. I have replaced both CV axles, both bearings, tires, and wheels. Even when putting the car on jack stands and pulling everything off I still get the vibration when I run the car up to at least 60 mph. What would or could cause the vibration? Timing belt? Motor mount? Any help is greatly appreciated!!!

 

what kind of vibration is it? rotational (constant?) or does it come & go.
is it more rpm or speed related?
sometimes loose steering componets cause the knuckle to move left & right & makeside to sidemovement of the tire making a vibration. check for loose tie rods (inner & outer), rack & pinion.
also loose lower control arm bushing can cause the same side to side movement.
let me know would ya, ill help u however i can

 

It's probably due to your tires. Try rebalancing your tires and see if the vibration persists.
