95 pontiac sunfire makes a loud howling noise faster you go the louder it gets.there is no noise when you turn or anything tho not shur if the wheelbaerings or cv joint going bad.

Check

#1. Rear Tires
#2. Rear differential
#3. Transmission
#4. Ball Joints / CV

find a new mechanic.

Not sure on your model but maybe a relay clicking in and out on top of the heater. That is about all there is there.

if it gets louder and faster as the engine speed increases then a piston is knocking...if it is just at idle like you said then it could be a bad oil pump if oil light is on at idle or it could be the connecting rod knocking on the crankshaft because it is loose.

Usually, a loud clicking noise is indicative of a bad axle. You could also have a loose/damaged wheel bearing.

if it gets louder when you turn left then the right front wheel bearing is bad and vice versa it gets louder when the weight shifts to that wheel

well did the noise start after the tires were rotated?could be choppy tires,,,if not ,i strongly think it sounds like a bad wheel bearing,,,,if you drive and while its making the noise turn left and right quick and see if the noise gets louder and which way turning makes it louder,,if you turn leftand it gets louder its usually the right wheels bearing as you are putting load on it, if it makes the noise louder while turning right its the left wheel bearing,,,got it

its suonds like rear wheel barring u need to eras the car and turn the rear tire to see which side exactly then replace ir

might be one of your catalytic converters clogging up. usually happens after engine has been running for a time? mostly heard when you let off the gas pedal? does the noise appear to be coming from the transfer case area? i thought i was having tranny problems, but turned out to be one of the catalytic converters. whew....

You must replace wheel bearings in pairs to avoid loading the old bearing and, in time ruining your new bearing hub it is possible that you have already damaged the new hub
