Question about Cars & Trucks

Open Question

My navien CH240 unit keeps getting the 12e error and shutting down. It also makes a loud humming and vibrating sound when it kicks on. Any quick fixes for this issue.

The only way I can get the unit to start back up is to turn the power off, wait 10 seconds, and turn it back on. However, this usually only lasts a few hours before I have to do it again.

SOURCE: 2000 Pontiac Montana Making a Loud Vibrating Noise in Back End

If you have a front wheel drive and not a AWD montana, it could be a bad wheel bearing or a brake shoe that may have broken loose.
Most likely it's going to be a bad rear wheel bearing and it takes less then 2 hours to replace. You can pick up the wheel bearing at Auto Zone or Parts Source for around $170.00 and they have all the instructions for you to do thew job your self if you like.
Tool's you will need: Jack Stand Ratchet with a 1/2 socket and extention Large screw driver 5 pound hammer Lock tight
To check if it is your bearing, try shaking the van from Side to side from the wheel. Listen and feel for any play, the bearing it self is sealed and the bearing my have gone dry.
Good luck and hope this helps. Oh you do not have to remove the brakes to do this job and use the screw driver from the top to split the bearing from the brake housing after you hammer it free from the Axle.

POWER STEERING PROBLEM - CONTAINER CONSIST TWO LEVELS. SHOULD THE BOTTOM PART BE THE NORMAL COLOUR OF THE FLUID AND THE TOP PART APPEARS TO BE DIFFERENT THEN REMOVE THE CONTAINER AND CLEAN PROPERLY AS THERE IS A SIEVE BETWEEN THE TWO LEVELS WHICH IS BLOCKED. DRAIN OIL FROM POWER STEERING SYSTEM AND REFILL WITH NEW OIL.
iF BELTS WERE RECENTLY CHANGED THEN THE PROBLEM MIGHT LY BY ONE OF THE PULLEYS THAT IS WARN. MEANING THAT THE BELT INBEDDS TO DEEP INTO THE PULLEY AND CAUSE THE BELT TO SQUEL. SHOULD YOU POUR WATER ONTO THE BELT WHILE IT IS SQUELING IT PROVES THAT IT IS EITHER THE BELT THAT NEEDS REPLACELMENT OR ONE OF THE PULLEY PROVIDING THE BELT TENSION IS INSPECT

My car makes loud sound when i drive and the car shakes and vibrates when i stop at a red light and still keeps making the loud stound . any idea whats the problem and how much it will cost me around


Have the sound investigated immediately as from your description it may be a major engine failure in the making. If it is then the fix will be another engine and that will be expensive.;

1996 ford contour loud humming noise and vibration from front wheels


You have a defective wheel bearing most likely, the noise sounds correct for that problem. have a shop drive it before you replace anything to confirm my guess.

After I turn off my car I hear the sound of a motor running and a black tube-like cable vibrates. What is it?


It probably is your radiator cooling fan. It will run until the car temperature drops to near level temperature The line vibrating is more than likely just vibration of the which is nothing unusual.Hope this helps;

Loud hum from under the hood. heavy vibration fron air filter all the way to top of engine


Hello,
I think the loud hum is coming from the exhurst. The exhurst either has a cut/hole or the rubber holding the exhurst has removed. This will make the exhurst begin to shake and vibrate.
Turn on the car, go under the car, then ask someone to press the throttle. This will reveal where the vibration is coming from.
Keep me posted.
Good luck.

My car vibrates causing this loud hum while


Hi:
;You most likely have a wheel bearling or hub assembly that is bad. You should be able to narrow the hum down to one side or the other. Other possibilities are a noisy engine accessory, such as a bad bearing on a alternator, or power steering pump, but you should be able to make that noise show up, just by rev ving up the engine, so if it only shows up when the car is moving, check out your wheel bearings.
