loud bang when leaving stall
« on: December 05, 2009, 09:51:43 am »
yesterday and today when I pulled away from a side road with a lot of snow, I would accelerate to leave and would hear a bang right when the vehicle moved, just now it happened at kal tire to the point I nearly had to launch to break it free, and the bang was louder, the guys here said it was the snow built up on my rims nd rotors that froze, but I think it may be the diff, if I remember, the ebrake locks the diff?, ahh what do you guys think?!

I'd say it's probably snow/ice freezing between the pads and rotors.  I get this on my STI as well.

Even in the summer time when I wash my car and let it sit, the pads kinda get stuck on the rotors due to surface rust and they make a loud noise when I move the car.

FYI the ebrake locks the rear rotors mechanically with a cable

can it harm anything with trying to move your vehicle more forcefully when this happens?...

Warm tires melt snow and freeze you to the ground too. That happens frequently to me.

I remember when it first happened to my wife last year she thought she'd broke something on the Leggy.

Both of our Subarus (97, 04) do this when cold. I suspect the parking-brake-in-hub thing.

Pour some hot water onto your rear rotor if you ever have this issue again.

It's been happening to my car all day.  Everytime I park the car for a couple of minutes, the brakes freeze up.  I'm almost getting used to it now.

Had something similar + this.

When I'm inside the car from a cold start it sounds like my exhaust is broken or missing the mufflers. And sound gets louder when I rev the engine.
But when I'm standing outside it is a lot quieter.  As soon as I'm in gear and drive away the noise is gone, and sometimes very subtle when I'm neutral waiting for a light.

I'm guessing it's the large chunks of ice I saw sticking to the under carriage and the cats on the exhaust (got myself high centered on a empty road in a commercial district the night before)  I hope it's just ice, I was kinda freaked out that my preza sounded like it was busted up this morning.  Going to try and melt some ice at a car wash if any are open,  need to get all that snow/ice packed into my wheels anyway.

could have been ice built up for sure, mine had a rattling/clanking noise earlier, then again plowing through snow drifts then parking for the night could cause that....

:P
