main shaft bearing
A grinding noise when accelerating in a 2000 Dodge Caravan could be caused by several issues, including worn or damaged transmission components, such as gears or bearings. It might also indicate problems with the drive axles or CV joints, which can produce grinding sounds when they fail. Additionally, low or contaminated transmission fluid could contribute to poor lubrication, resulting in grinding noises. It's important to have a qualified mechanic inspect the vehicle to diagnose and address the issue properly.
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.
possibly your wheel bearing is on its way out
To stop a standard transmission from grinding into third gear, check the level of the transmission fluid. If the noise continues, consult a mechanic.
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
if its a front wheel drive vehicle then it could be the axels
could be a wheel bearing...or just that its a french car
sounds more like transmission slipping diff slipping would cause loud grinding or howling noise
