Knocking sound OSF

Post by sadako »

Greetings,

Today I started to get a wierd knocking sound as I go along. The front discs are sligtly warped but I am barning the car for the summer soon so am not in a hurry to replace them. The slower I go the more noticable it is. Turning and braking seem to stop or reduce it. I jacked the wheel up at lunchtime in the office car park and the wheel moves freely, doesn't knock when not under load and there is no apparent play in the bearing/stub axle.

Can anyone suggest what it is? Is the car likely to be unsafe to drive?

I am taking it slowly in the meantime until I can use my other car.

Check the ARB droplink and mounts. Also check there isn't something caught in the wheel - I once had a noise which turned out to be a bit of wood caught in the brake caliper

st haok, i jud the arb mounts welded up to pass the mot so it was recently disturbed. ites sounds like the knock happens as the wheel rotates though... the wheel seemed to be free when i jacked the car up as well, i didnt see anything stuck in the caliper when i did that also. I will doublecheck this weekend if i don't get any messages warning me that the fault is dangerous - i prefer to arrive with a full set of wheels :)

Wow that last post I made from my G1 was pretty unreadable. Fault turned out to be something really dumb: just one wheel nut had come loose. The slightly warped disc shaking it around must've done it. Still, car gets put into storage saturday week so replacing the discs can wait...
