What would cause a constant roarng Noise from rear of 2003 neon front wheel drive?

This could be a bad strut or ball joint. If the noise is constant when you drive this is probably the cause. If the noise only happens when you hit a bigger bump/pothole I would check your motor mounts, this was the cause on my thunderbird.

Could be a universal joint. If front wheel drive, it could be the constant velocity joint. I am assuming you have an automatic transmission. If it is a standard transmission, it could be the throwout bearing.

On a front wheel drive car probably a damaged constant velocity joint clattering

There can be several things that will cause your 1994 Jeep grand Cherokee to make a loud clanking noise when you drive it. The most common cause is a bad u-joint.

possibly a bad brake...you should get all brakes done

If its front wheel drive possibly an axle.

it could be a bad universal joint.

An accessory drive belt idler pulley bearing going bad.

If the chirping noise speeds up as the truck speeds up, check the u-joints in the drive line.

The rear of a Ford Explorer may have a grinding noise when driving, because the muffler may have came loose. The u joint may also be loose and cause a grinding noise.

Sometimes squeaky noises can be a result of a damaged belt. When you speed up, the noise goes away. You should get your car inspected by a mechanic.

It depends on when you hear the noise, but it likely a joint in the front wheel drive unit.

Assuming it is front wheel or 4 wheel drive, it is worn CV or Constant Velocity Joints. :o)

c/v axle is bad if its front wheel drive

glazing of the belt may cause that noise time to replace,little bit of dish soap will take it away

If you think there is something wrong with your car, you should not drive it until it is fixed because if it is faulty you could have or cause an accident which may seriously hurt or kill someone.

Check the fluid level in the transmission. Sound like a part may be going out inside the torque converter or transmission itself.

need to know what causes my car to make a heavy noise when driving. i have changed both front bearings but have discovered the noise still exist. Could it be a problem with the drive axlel?

IT COULD BE A WHEEL BEARING THAT IS BEGINNING TO GO OR the constant velocity shaft of the fwd unit. If you start hearing a "clunking" noise when you turn it's the shaft. In any event, it needs to be checked out by a good mechanic

You need to take it to the garage and take the mechanic or shio foreman for a ride and show him what you are talking about. Make sure he hears the noise and knows what you want.

If it's a clunk sound, check universal joint bearings and drive shaft bolts. Otherwise please describe noise.

Normally this is the drive belt. Inspect the drive belt, and replace if worn. A loose belt may also cause this noise.

If the noise is coming from the engine area, it is most likely a loose and/or worn drive belt. Try pouring water on the belt when it makes the noise. If noise goes away, then suspect a belt.

You should check the dual pump fluid in the diff. It is a common problem on the CRV. Drive in a constant circle and you will hear a similar noise.

If the drive still works it is most likely early stages of the spindle bearings failing. This cannot be fixed, copy the contents to a different drive ASAP. If the drive no longer works one possibility is a crashed head dragging on its platter.
