Question about 2007 Scion tC Coupe

1 Answer

Front axel(?) noise

When coasting with the clutch disengaged or braking at all, my Scion makes the following noises:

wom-wom-wom-wom + grindygrindygrind

It's definitely coming from the front of the car. The tires are fine; properly inflated and maintained very well. I have about 27000 miles on the car and have never had any accidents. Sometimes, I also feel a shimmy.

If you are driving and you put the vehicle in neutral and coast, push the brake pedal and NOT the clutch pedal and see if the noise is still there. If the noise is there, then you will need to get your brakes checked out. If the noise only happens when the clutch is pushed in, then your clutch release bearing might have something wrong with it. I hope this info helps.

Front end humming


noise is a bad sign, best is to have mechanic find it
some noises can be very very dangerous to driver for sure
the testing person,
makes noise only moving, in all gears
does it make noise moving in Neutral, coasting,
does doing that, and carefully stalling engine coasting with noise stop the noise.... yes, find a safe place to do that.
i use a steelman electronic stethoscope to find most noises.
it has a clamp on microphone, its like a $35 tools, way less that taking the whole car apart.
it will find which corner or better.
sounds to me like a bad wheel bearing.
or bent backing plate
or caliper guide pins jammed, ,rusted, or bean rotor. or? or ?
if the 4wd is disengaged, the front gears dont turn, so.....
in fact that is it prime purpose... if the the air pump is off and the lever retrated, its off. id check that tool... is front axle decoupled.....
the FSM covers this test in 1 page.

Could be u-joints. Play goes away under Torque (accelerating) and returns when parts shift (unload) from Torque like coasting or braking.

Transmission or Torque converter not disengaging, hanging up in overdrive.

Does it make this noise every time you push in on the clutch, or just when coasting?
If it always makes noise when you push in the clutch, it could be the throw out bearing.
But if only coasting and not when turning left a little, then a front wheel bearing is more likely.
The brake will also wear faster, get hotter, feel a little spongy at first hit, and the brake pedal will vibrate if the wheel bearing is going. But if it is a wheel bearing, you can wait until it is worse.

I have a 2007 Chevrolet Cobalt. Recently during a snow storm the vehicle went through a ditch. No damage was done to the car. It was the most minute accident ever. Anyways the next day i noticed some noise...


Based on your description, I'm thinking the problem is in the transmission casing. I was thinking it was a wheel bearing, based on your description, but that is contradicted by the fact that you say it doesn't sound like it's a wheel or hub bearing.

You say that the the rf cv axle is now leaking where it goes into the trans. I'd say that's a good place to start looking.

A damaged cv axle or half shaft might make more clicking noises on a tight turn. The cv axle is greased up and has balls inside some designs.

Have you checked the transmission fluid level to see how much fluid has been lost thorugh the place where the cv axle enters the trans.? If adding fluid makes the sound lessen or go away, then the trans. is at fault, vs. the cv axle.

Good luck on this repair.

Medozachris8,

Ouch, sorry to hear about your clutch. Have you tried contacting your local Scion dealership? They'll definitely be able to get down to the bottom of this and get your back to smooth driving in no time. Also, you might want to check out Scion discussion forums like www.scionlife.com. I did a quick search for you on "rough clutch" and here are the thread results - http://www.scionlife.com/forums/search.php?searchid=2093756
