main shaft bearing
Could be a number of things. Is the noise coming from your transmission, your rear differential, one of the wheels? From the wheels it could be a warped rotor or a wheel bearing failing.
More likely the bearings in your alternator wearing out. Get a new alternator.
You need to lubricate and clean it.
Your question is vague, but since you used the words "squealing/grinding" I first start to look at the brakes. The squealing could be coming from your brake pads. Some brake pads come with a safety mechanism that alerts to when the brake pads are nearing replacement time. If you ignore that squealing then it turns to a grinding because there ain't no brake pad left. At this point, you're now looking at replacing the rotors as well as the pads. Rule of thumb is that if one side is bad then the other is just as bad or not far behind it.
To stop a standard transmission from grinding into third gear, check the level of the transmission fluid. If the noise continues, consult a mechanic.
possibly your wheel bearing is on its way out
If the transmission is grinding on a 1997 Honda Civic then the gears are worn down. The transmission will soon need a rebuild so it can operate smoothly.
No! Something is wrong.
it needs a new transmission
could be a wheel bearing...or just that its a french car
if its a front wheel drive vehicle then it could be the axels
A bad transmission. The sound is from metal grinding on eachother.
sounds more like transmission slipping diff slipping would cause loud grinding or howling noise
The grinding noise can be an indication of a bad gear in the transmission. The grinding noise can also indicate a problem with the clutch.
That's just the rev of the car. This means you are accelerating too fast. Go nice and steady.
When it is time to change the brakes on your 2001 Mitsubishi Montero, they will make noises. There could be a grinding or squealing noise that you will hear.
You probably have something wrong with your engine, or brakes. You should really have that checked.
"Grinding" isn't nearly enough information, but the automatic transmission on the 91 to 94 explorers are notoriously weak and very prone to failure.
Noises have to be heard to be correctly diagnoised. Check the motor mounts to see if they are broken.
If the transmission is slipping on take off, but there is plenty of fluid, the gears may be frozen up. This can also make a grinding noise upon acceleration.
I have mercury mountaineer 4x4 03 had grinding noise easy fix remove the shaft which connects the transmission to the rear end
engine problems not trans.
Really it depends on the driver and how hard they break and if the break pads need replacing or not. I'll just give you some simple answers... Screeching Silent Grinding Squealing
The A4LD transmission is the most common failure on early explorers. It's very likely that your transmission is failing.
countershaft bearing could be problem
