Noise: Je ne comprende pas
Posted: Tue Sep 02, 2003 1:56 pm
Probably misspelled that, but anyway:
There's noises coming from the front of the car, when going through small potholes and/or up and down sharpish speed bumps. It's only there when the suspension has to cope with harsh bumps at low speeds. At higher speeds, there's silence. The noise can best be described as metal-to-metal knocking sounds.
Now, this is why I don't get it:
I had the noise when the car was on Raceland springs and shocks. Then I switched to KW's, set to -80 (or something), in any case I had 45mm left on the front shocks' thread. At that setting, all went quiet and it handled like a dream. I was quite pleased to get rid of the knocking sounds from the front suspension. I figured that the KW's were simply better quality, and that the Raceland bits were at fault, or that my suspension bearings were shot. Alternatively, I thought, the anti roll bar could be banging on the chassis somewhere. But then, lowering would only make it worse, not better. I changed the bearings, by the way.
Come today, and I raise the car 20mm, since I couldn't get on and off the driveway without scraping. The car still handles fine, but the noise is back. It's as if the springs are decompressed when driving on a smooth road, but then compress causing the spring to re-seat itself to the spring cup. This can't be however, since the KW's have helper springs to counteract this- and again, it would be worse if lowered and not better.
I'm not too pleased, to be honest. I could drop it some more again, but then I couldn't go very far, or, I'd have to park the car somewhere in front of the house. Besides, it also rubbed on harsh dips and bumps, which, admittedly, could be solved with a harder setting. Anyway. It shouldn't make noises, regardless of the height.
Anyone have a clue? All help much appreciated.
The KW's are fantastic btw!
