Grinding Noise On Start Up And Driving

[KerrodR33]

Having troubles with my 1996 gtst. Upon cold start up I can hear a grinding/scraping noise similar to a grinding wheel.

The noise can be heard while driving in the low rev range but I can't tell if it still makes the noise at higher rev ranges due to the car being too loud. When disengaging the clutch the noise quietens due to revs dropping.

I don't know if it's related but my alternator is squeaking as well.

Cheers for any help guys

I say get it up on a stand or jacks and search for the noise.

Sometimes when its really cold down here (this morning)

I had a grinding noise from my clutch but that is a bearing that needs to be replaced.

Just try searching for it and see if it still happens when at a stand still or not.

Could be wheel bearings or brakes

Do you think the lower rpms you are also doing a slower speed or same speed?

The noise is definitely not from brakes or wheel bearings as it's making the sound at idle as well. It is more of a schhhhhh sound lol. Sort of like the vaccuum thing at the dentist with a hint of rubbing. That's the best I can describe it haha.

Go buy some hose and a funnel.

If its loud enough you can get the hose and search around the areas with it and have the funnel to your ear.

If you were in ACT I would lend you my high tech one lol

...or a wooden dowel placed between your ear and parts of the engine/pulley shaft ends/hoses (-better than a screwdriver) > locates noise sources

My mate had a similar issue, turned out to be the diff.

It was a grinding noise when he revved the car, so yeh kinda similar to yours
