Car making weird noise

[nkwrx]

...as above. Noise coming from rear end and sounds like when you blow over the neck of a bottle? Only seems to happen after an "energetic" drive and is audible at anything below 25mph ish. Stops completely when brakes are applied and disappears after 5 mins or so.Any ideas anyone??  06 WRX Hawkeye

i used to get that when i gave my old my05 wrx not sure what it was [:S]

Kev, could be the brakes binding or something like that. Take it to the dealers and see what they say. I have what sounds like a rear wheel bearing gone on my 05, it makes a squeeky noise but it still makes it with the brakes applied. Only goes away when stopped, and increases/decreases in intensity depending on speed.

Hey mate,

sounds more like it could be a wheel bearing,or maybe the diff?

When did the oil in diff last get changed?

[nkwrx]

Thanks for the replies guys. st3ph3n, had wondered about the brakes binding as it stops the noise applying the brakes so a trip to dealers seems in order. ScoobyBB, car has only done 15k mls so don't imagine the diff oil has been changed at all but worth investigating too. cheers Lads  Kevan

Hey mate,

Work as a mechanic my self and had a scooby in the garage wi noise from rear and it had only done few miles can't remember how much to be exact.turned out to be rear diff.

Good luck on finding the problem tho mate.

Sounds pretty similar to what I had with my 2002 WRX a few months ago. Got a dull squeal at really low speeds and dissapeared once you went faster or when you applied the brakes. I put it down to the brakes binding or something along those lines as the car had only done about 4k a year prior to me buying it. However, over the space of the next 1000 miles or so the squeal became a a grind and it turned out the brake pads were goosed.

This was at around the 18k - 20k mile mark, which the dealer said was the normal lifespan for a set of standard pads.

Got Greers to put a set of pads on, and have never had the noise again.

I got 30K+ out of a set of rear pads. With trackdays. The dealer is obviously slowing down too much.

The previous owner of mine must never have been off the brakes! [:S]
