Peugeot 307 1.6 D - Engine Knowcking Noise afer Snow - ColW

Our Peugeot has been stuck in snow for a few days and when I finally drove it out (over some compact snow) it has started making a knocking (big-endy) type noise from the rear.

All I can add is that the frequency of the knocking increases with speed and disappears under road noise above about 30-40mph. Also, weirdly to me, at lower, noisier speeds, if I compress the brake the noise disappears immediately, i.e. before I have really decreased in speed at all.

Can anyone make any suggestions as to what it might be?

Thanks in advance.

Col

I expect you have some lumps of frozen ice/snow trapped in the back wheels or brakes, causing this knocking.

Short of getting it in a heated grage, I expect it will continue until it wears away or the temps increase and it melts.

I had snow frozen in my back wheels once, after I had been doing hand brake turns in the snow, it caused wheel imbalance, the whole back of the car vibrated., until I knocked it out with a stick.

Could have broken an exhaust mounting bracket.

Just got round to looking at this.

My back right brake disc does not turn when the alloy turns! Left is OK.

O dear, wheel nuts seem seized a bit too so I'll get it inside and do it properly. Anyone familiar with the car can tell me what bits to order? bearing?

Thanks, Col

Physically impossible. Studs holding on wheels go through disc hub.

Unless there's a circular crack round the disc hub?
