I have a scraping, or grinding sound when I accelerate. Its a 04 accord. I was told its not a brake issue. Any thoughts?

Noise is a hard one to figure out without hearing it. Have you gone to a garage and put it up on a hoist? I'm sure that when you had the transmission work that they checked the u-joints, maybe? A flex plate that has a crack will make noise, but they looked at that when the transmission was out right? Possible bad motor mounts allowing the engine to shift and the fan hit the shroud. Can you duplicate the noise by with your foot on the brake and the car in gear start to rev the engine? Is there a baffle in the muffler or catalytic converter? Lots of possibilities.

What does the noise sound like ? Grinding, scraping, clicking . What all was replaced ?

A timing belt usually makes a loud squealing noise (like a 'shriek/scream') when it is worn or slipping, not a grinding noise.

A quick check - before you start the car - is to pour some water onto the inside of the belt where it goes around the pulleys. If there's no noise at start up, you know it is the belt at fault (or the metal pulley/s are worn).

There are kits to replace the timing belt (and bearings). Have a look on Ebay:

If the noise happens before the car moves - it obviously can't be your brakes. When backing up the noise may appear louder simply because your head is turned ..

If the noise is actually coming from a wheel, it possibly could be the backing plate on the brakes - the thin disk behind the brake may be rubbing on the rotor.

However.. a grinding noise ... if it is coming from the front of the engine in the general area of the timing belt be very wary - if a bearing or the belt fails, your engine will be history.

Why not give a mobile mechanic a call? Those guys are usually quite good and a lot cheaper than a workshop

will try to assist you. did you have your clutch replaced professionally? if it's a popping or cracking sound when accelerating or turning, it's most likely a c.v. axle going bad. either on driver or passenger side in the front of the car right?if it is a bad c.v. axle it will pop and crack when you turn wheel from left to right at low r.p.m. if not this,you may have brake issues. either it's a grinding sound while accelerating or decellerating,as long as cars in motion the noise will persist.try tapping your brakes while in a parking lot in slow gear,hear something from driver front,have a passenger with the widow down on passenger side, hear it from front passenger side? the thing i go by is what i hear when i test drive to diagnose an issue with a vehicle is,axles?popping and cracking when turning the steering wheel from left to right at low speed. [axle problem] grinding,scraping sound? brake issues! hope this helps and thank you for choosing fixya.com and we are here for you 24/7 7days per week thank you!!!!

you need new brake pads

that is the sound of the brake pads minimum low warning clips,wich means u are due for new frt brakes.

Have the front brakes checked alot of times the brake pads wear down to the point that the wear warning indicator starts to rub on the rotor or disc and makes a scraping sound when turning, your front brake pads are due to be replaced, I am 80% sure.

i think its the axel bearings(or)the front bearing at yoke at front of rear end

check cv axle and make sure it did not pop out of transaxle

Sometimes these things happen and even after servicing them they come back again..If you want to be safe then have the braking system serviced...which means removing every pad and clean everything...Once all is put back you should be fine..
