Noise from tyres on full lock

Rotty · 28 Oct 2008 at 23:36

The Cayman makes a clicking noise from front tyres on full lock at low speed, prob worse in reverse

The M3 did the same too

is it just a case of the edges of wide tyres being at such an angle (if that mkaes sense) or soemthing else ?

Most cars I have owned seem to emit a humming noise when the steering is held on full lock, even when stationary. I assume it's something to do with the power steering. Would this be the case with yours?

not a humming noise., more of a thud thud thud as if the tread of the tyres is at too steep an angle

tractors do this too on full lock, if that helps. doubt it does tho.

Think it's the PAS, I remember my driving instructor telling me to always not quite use full lock if doing a lot of low speed manoevures.

I had that on the other halfs car shortly before the alternator fell off taking the pas belt with it

Pressure relief valve in the power steering probably. Won't happen if you're at full lock, but not pushing it against the stops.

Was going to say CV joints, but then I saw the car.

I have always assumed its this.

My VW Golf makes that noise aswell on full lock, can even feel slight vibrations from it when moving very slow in full lock.

I had noises when cornering hard, turned out to be low PAS fluid.

Was waiting for someone to say it

My S-class does this on its huge tyres, always assumed it was the angle as you are.

Firestar_3x · 29 Oct 2008 at 08:55

Mine does this on full lock and low very low speeds, think its the angle of the inner tread against the road.

all the porsches I have (lol at me ever being able to write that) do that

My 987S sounds/feels odd at full lock too mate. Feels 'wrong' doesn't it?

Feels more than just the camber causing judder as the tread rides the floor...

good to hear it's not just me then

bloody thing has already cost me some money though

had a grating noise on right hand bends/roundabouts

they had to strip the brakes to remove a stone trapped behind the disc, £103

not asked but fairly sure the warranty wouldn't want to know as it could easily have happened after I got the car

Barry Smalley · 29 Oct 2008 at 13:33

It's either the PAS relief valve or some scrubbing going on with the tyres when its moving.

Does it make the same noise when it's on full lock (held hard over), when you aren't moving?

Rotty · 29 Oct 2008 at 13:33

nope, only when moving

I think, will check though
