Squeak

[GreenMachine]

Hi,

Last few weeks the front left (nr side) has developed a squeak when I go over bumps. I think its coming from the strut but cant be sure, and doesn't do it if I bounce it when stationary. I had an advisory for worn bushes on the MOT, could this be the problem?

Not the best diagnostics done but its hard to tell exactly where its coming from whilst driving.

Any ideas?

get a mate to drive it along over some speed ramps while you run along side?

if you had an advisory for bushes, i'd start with changing them and see if that improves it. you could also try soaking the bush with water and quickly taking the car to somewhere you know it squeaks - the water will lubricate the rubber enough to (probably) stop the squeak

My A6 used to squeek before I changed the suspension bushes so there's a good chance that's what it'll be.

I immediately assumed it would be bushes before you mentioned it.

I found the problem. Its where the front flexi brake pipe goes through the bracket just before it connects to the rigid pipe. There is nothing stopping sliding up and down on the conector when the wheels travel up and down.

Any suggestions on what I can use to stop it from happening. Ill take a picture if I haven't explained it too well.

There should be a rubber grommet to protect the flexi hose. If it has got the rubber grommet and still squeaks you could use a water based lubricant (like KY jelly) to lubricate the hose.

Rubber gromit is missing. Where can I get a new one? will I have to disconnect the brake pipes to put it on (re bleed it)???

the flexi should be secured to the strut, and a pedantic mot tester may fail it for not being. cable ties are your friend ;)

The flexi pipe is attatched to the strut via a cable tie. It's the bracket that's attatched to wheel arch just before it attatches to the rigid brake pipe. It's was mot like that so no problems there.
