Question about 2001 Toyota Echo

1 Answer

'00...noise (sounds like it could be a bearing) when the defroster is turned on. Same noise is heard when the A/C is activated. If they are left off, everything is normal. The interior fan functions as normal--no noise and although the defroster cycle is noisy, it does work....same for the A/C. I tried listening (with a long dowel) to the a/c compressor, altermator, power steering pump and the cooling fan (radiator) and cannot detect any sound difference with the a/c on, defrost on,....or off. Any suggestions???

Check the heater fan motor they have a tendency to have the shaft bearing wear out and make a squealing noise from time to time depending on how the shaft wobbles and that is the reason you don't hear it when the heater and ac is off.

SOURCE: noisy rear bearing?

Is isnt the rear end it would be very bad shaking and wouldnt last long because it would throw a bearing out. So its most likly the wheel bearing and you can just take it to a local automotive shop.

Probably your power steering pump is going out or your power steering hose.

you should check the fan blower module. it is normally located under the passenger side dash, it is just a small circuit board that has resistors on it, they sometimes melt off. this could be the problem. or the blower might be stuck or broken

You can unplug the clutch that engages the compressor. Look for wires that come from the compressor. Trace them to the nearest plug and unplug them. The compressor will no longer come on.

Hyundai Accent 2016, 4811 km. makes grinding noice which can be heard when driving on smooth asphalt road. Noice is on for a while and then you don't hear it for a while. What can be the problem?


Wheel bearings could be the problem. While moving and steering to the left, if the noise increases, it could be the RIGHT wheel bearing. And the opposite when steering to the right. I wouldn't rule out brake noise though. Rotors almost overnight get a surface rust and must be worn off when first driving in the morning. Very common in high humid areas.

Linc LS 00 left rear wheel bearing making noise , increase acceleration noise it goes away sounds like a sqeek certain spot on rotation


probably not a bearing but a low disc pad indicator rubbing on the disc rotor
check pad thickness and if close to 1/8 inch , replace the pads
bearings rumble and are worse on cornering

X type 2.2d 2007 Noises when turning left. Have experimented a bit since I first heard the noise and if I turn the steering hard left then accelerate slowly until I am going round in circles fairly fast...


you seem to have a sheering hub bearing. ..the car will have to be raised and to checked but this is usually the issue with that car...I have seen it on xj and x type and some s types also...the noise will get worse as you drive it, but if the sound is a low humming sounds usually thats it,but if its a grinding sound and the car leaning in the rear to the side that has the noise then it is usually a carrier bearing...get her on a stand and keep me posted.

I hear a progressively louder, almost metal-on-metal sound behind my front passenger tire while I'm driving, regardless of braking or accelerating. I was told a couple months ago to change my tie rod soon...


prob a wheel bearing if you think its a tie rod just leave the car off and get under it and wiggle the long arms connecting the front wheels.
if its wheel bearing jack that tire off the ground and try to wiggle it.
ultimatly goto the tire shop and have them look at it.

Grinding noise changes with speed stops when turned right. replaced left front wheel bearing. noise is still there. whats wrong ?


Does sound stop when you turn LEFT?

Turning RIGHT puts the heavy load on the LEFT front wheel.
That initially STOPPED the noise, correct? So why did you change L?

Turning LEFT puts the load on the RIGHT. Did you change the RIGHT?

Let's say this:
If turning RIGHT stops the noise, it's the RIGHT one that's likely bad.
If turning LEFT stops the noise, it's the LEFT one that's more likely bad.

Make sense? Turning RIGHT loads the LEFT wheel; and vice-versa as the WEIGHT SHIFTS AWAY FROM THE TURN.

More than likely it is what some folks call a CV joint problem, not wheel bearings. Try backing up and then going forward to see if "clunking sound" or a sharp "bang" is heard. Wheel bearings and CV joints only work if smooth. Sometimes a BEARING RACE is bad. Also, a bad spindle / part of the CV joint / transaxle assembly worn or badly machined. If in a WET ENVIRONMENT especially, u may want to try marine grade grease or teflon-added grease.




Does sound come from POWER STEERING PUMP area?
