Boxster 986 '97 noise at low speeds

[Antti Kantola]

Hello

Last time i got great help from you guys when my coolant system was leaking. I got it fixed and it's all thanks to you!

Now i have a new problem. My 986 makes squeaking noise at ~5-20 km/h speed. The noise comes louder when i steer right. The noise comes somewhere near left rear wheel. The brakes have been replaced recently and i think brakes make different kind of noise?. Please see the video in youtube http://www.youtube.com/watch?v=slZvKc-yE-8. How can i debug this and what should i check first?

It is probably the brake pad touching the brakes disc, or the metal brake disc guard touching the brake disc. When you steer right it places greater load on the left wheels which has a tendancy to make the brake disc move slightly out of line and touch the pad or the guard. If your wheel bearings are worn this is more likely to happen. Also, you might have something caught between the guard and the disc.

Jack up the offending wheel and turn it by hand to see if you can locate the noise. If you can, take the wheel off to get a closer look. If the noise is being caused by the guard just ease it away from the disc with a lever. If it's the disc brake pad making the noise it might be a stone, or a bit of wire, caught on the edge of the pad.

Does the noise disappear when you apply slight brake pressure?

I would not rule out a rear wheel bearing - especially if the car has over 60,000 miles (96,500 km).

Thanks i'll try turning the wheel and report my findings.
