2002 volkswagen jetta, I have a roaring sound when I accelerate

What do think could possibly cause a roaring sound when I accelerate. It does not appear to be coming from my engine, but somewhere to the front right of my car. When vehicle is put in parked, but still on, the sound is not heard. Please help!

It's your wheel bearings. I just had the same problem with my 2002 GLX with 100,000 miles. My dealership replaced them for a tidy $700 as I was in a jam and needed to get back on the road a.s.a.p.

You can pick up a set of bearing online for 90-100 dollars and change them in a couple hours. If you or someone you know is a good mechanic, it's a pretty simple job.

NOW I have a CV joint that is going bad, but it POPS and cracks as I turn corners. Its a distinctive sound.

If you hear the noise while the car is moving and usually accelerating and there is no noise when it is not moving then it could be a problem with the transmission, CV Joints or wheel bearings. From the way you describe it sounds like the CV Joints. These are the ones that transfer power from the transmission to the wheel while they allow the suspension to move up and down. If they wear out or get dirty they will start making a grinding / buzzing sound. You will find them ( 2 on each side ) connecting the center of the wheel to the transmission. There are 2 rubber boots protecting them, one close to the transmission, one close to the wheel. The joints have to be kept lubricated and clean, if any of these rubber boots is broken there is a good possibility that the CV Joint is failing and making the noise. If this is the case it will need replacement.

Shaking when accelerating


It could be loose or broken motor/transmission mounts. Since it only does it on acceleration, I don't think the tires would be the problem.

sounds like a gearbox bearing ,,,this sounds like a growling noise usually when accelerating although as the problem gets worse it can happen constantly ,,, wheel bearings can growl too but will give a constant noise regardless of acceleration ,,, you need to see to this quickly as the more you drive you will cause more damage and cost to you ,,,,bearings will fix it in the early stages but if more damage is done you could have to pay for new gears and shafts which is expensive
