Rubbing sound when accelerating and decelerating
 
I have an 08 wrx 40000 miles. When I accelerate or decelerate I notice a rubbing sound that is quite noticeable coming from my engine it sound like. Could this be motor mounts? Or something in the suspension?

Could be anything.... Could be something dragging under the car.

Does it happen when it's sitting still or just driving?
Does it happen when it's in neutral and rev'd sitting still or just driving?

Mods ?

What did you last do/have done to the car ?

Is it constant rubbing or like pulsed?

It only does it when I accelerate or apply torque to the engine. Doest do it in nuetral. Seems to be only
Making the noise if the engine shifts or torque is being applied or I am slowing the vehicle down. Nothing is dragging. This weekend I put an HKS EVC S boost controller on it but it was making the noise before that.

Dust shield from the brakes.... So when you are in neutral and coast to a stop, it doesn't do it at all ?

Got to be drivetrain if so. Didn't the 08's have throwout bearing issues?

Oh, and take that high $ POS MBC off. You tuned for it? (another issue, sorry)

It's rubbing for sure and not whining? Usually motor mounts will make sort of a thumping sound or vibrate and you can feel the vibration. Hard for me to swallow a car with 40000 on it with bad motor mounts too, unless the car has been clutched and shifted by a 6 year old it's entire life. Can you rock the motor by hand?

Got the mbc for 200. And I have tuned it according to specs from other drivers of the same controller with same cars and similar mods to mine. I have no issue with the mbc. It's aggressive pushing about 13.5 psi at higher rpms and a lower setting for economy. I haven't read any bad reviews about this product either, must be a preference thing.


The noise is a rubbing sound almost like a door opening that hasn't been greased in a while. Like a creaking noise but more fluid sounding and only when I apply torque Lethe engine moves.

The engine makes no sound in neutral and I can't think of anything else it is.

Is it loud enough to make a vid with audio and post it?

It is a preference thing.

Scoobydoo5 12-13-2011 01:29 PM

I will try to take a video after work hopefully the sound is noticeable.

Grab someone to take the vid when you are driving and have them try to pinpoint the area.

You know as a last resort you can take it to a place with a lift and pinpoint when the car is running on the lift (albeit not the safest thing to do, it may help).

I will have my roomate do it tonight.

Also I was looking for a nice tbe with duel tips instead of single can aftermarktet. Any ideas I can't find dual tip aftermarket exhaust for 2008 wrx.

Rotors are bad.

Scoobydoo5 12-13-2011 03:03 PM

Rotors? It makes the sound when I'm not breaking would my rotors still be making that sound?
