No,the motor-gearbox mechanism is sealed. You`ll probably need new motor brushes which you can get from a dealer or a new motor and/or gearbox.

Grinding noise in either motor, gearbox or drive shaft on low speed going uphill. Gets worse when going faster. Souns like something needs oil change or top-up.


Look at the universal joints on the 2 ends of the drive shaft. The hubs may have dried up and wore out you might be grinding metal. If so, you need to replace the universal joints before the drive shaft falls out.

Makes a grinding noise at higher speeds


If it is leaking you are going to have to go inside the gearbox to change the grease so whatever is wrong inside may become obvious when you take it apart. Remove accessory cap from the front and look for any dryish grindings inside there.

Grinding gearbox


Check the oil level ,if need be pump some LM grease into the gearbox about a GREASE GUN FULL will do this will seal up any leaks once its warm and melts in a bit ,the noise was the lay shaft bearings or the drive gear shaft bearings to the crownwheel ,faily common on peugeots and citreons but make sure you check the level use EP90

Question regarding KitchAid mixer, Model K45ss. The vertical mixer shaft has play in the gearbox, it makes worn gear noises at all speeds. I adjusted the speed control to manual specs, the speed control...


Yes this indeed does sound like you have a problem. There could be a couple different cause of this noise. If your main drive or worm gear has been damaged, it is likely to not run at all or jam up. So i think this is not the problem. There is however a codder pin located inside the transmission gears this can be seen by removing the upper housing of the unit, and then exposing the oil and gears. clear away the oil surrounding the gears, and save this grease for later. After this you should be able to visually see this codder pin AND the gears, rotate the gears while inspecting them and the pin. If the pin is slightly bent or broken this will make the grinding noise that your are talking about, while still operating and driving the unit. part number for the codder pin is 9705444. If however the noise is coming from the motor area this could indicate a worn or faulty motor bearing. This can cause the motor to operate on an angle and can cause a rubbing noise from the cooling fan or the winding of the motor itself rubbing on the mixer housing. Part number for the braket and bearing is 3180526. both are relatively cheap and easy to replace. If you find and fix the problem be sure to inspect or change the oil as this can often have metal chunks and other particles. Hope this Helps

Thanks

My 2002 Dodge Neon makes a loud, almost grinding noise in the front end which is worse in the morning and lessens as it drives and warms up. Hear the noise only at lower speeds. There is no vibration...


I'd say there's no grease left in the CV joint boots, if it's front wheel drive. Something you should check right away, as your car has about reached that age, and if you run it without grease in the boots, you'll eat up the joints in a big hurry, and that's costly and dangerous as well.

Asko T780 Dryer Vibrating/Grinding noise


Sounds like a bad roller. You'll have to remove the drum to get at them. Even a free one may make noise at speed. Use high temp grease. Also check roundness. And don't forget the belt tensioner roller, just don't get any grease where the belt touches.

Front drive train or axles?


Welcome to fixya

could be one of those but lets hope not it could also be the front bearings if it is the bearings it runs around 300 to fix if it is drive train or axles your talking a lot more money

OH check the break pads just thought of that if the pads are low it will make a noise to pull wheels off and check breaks first

hope this helps you out have a good day :)
