When driving 30 miles per hour and up to 45 mph i get a vibration from the front end. I took it to a dealer and they tolm me it needed a right front wheel bearing and a left front tie rod end. i replaced both parts myself and i still get the same vibration. what's up now?

When you took the car to the dealer did they realign the front end? If not then do so. Sometimes when the front end is out of alignment you will feel vibrations while driving.

This is an elusive problen to figure out!!! the problem is the cv joints, change the drive shafts an our problem is gone>

wheels need a balancing

I agree... sounds like wheel and tire balancing...

You have to make wheel alighment tire balancing befor your tire gets damage..

you were half right on the tie rods your right tie rods were bad. the hub bearing makes a constant growling noise, that you have ruffly 2-3 to change it or it lock up

So I had the same problem. I put it on stands and checked inner cv play and had a little movement on passenger side axle shaft. I bought a new one and installed only to find the same play. I suspected that the differential bearing might be bad on tranny causing the play. I call a transmission shop and spoke with a guy who said if the output seal was good the differential bearings not bad, and that 6 speed tranny's where notorious for bad compounders, but he would have to test drive it before saying for sure what it was. I also noticed excessive motor movement when holding brake and giving gas in gear, So i replaced the motor and tranny mounts. Still same problem. Took it to a friends to have him drive it. He said he thought the vibration was caused by the engine and tranfering to the wheels. I have had occasional misfire codes on cylinder #2 come up so I took plug out and checked for spark. I had none even though i replaced sparkplugs and wires recently. It was the coil pack that was bad. Bought a new one at Auto Value ($42) and installed. The problem with excessive vibration above 35 mph on slight acceleration cleared right up!

Didn't vibrate until I got the new tires put on took it back to check balance. Was a little off .re balanced and still vibrates bad at 30mph up to 45mph but let off the gas it stops give it gas and vibration starts
