Sport Creaking Noise from back axle

TTLandy said:

Hi, New to the site so forgive me if the post isn't right.

I have a 2009 RRS TDV8 that has started to produce a noise from the rear of the car - assume back axle. I've attached a short video clip taken by go pro from under the car that highlights the noise (its zipped). Main dealer and local garage cant pin point it - replaced the prop shaft (££) and the sway bar (£££) on their advice but no difference. Any ideas!

PS, I don't think I've run over a woodpecker!

That sounds more like jumping splines or broken half shafts ,some thing rotational .

• The noise is intermittent - it does not happen all the time. But it is getting gradually more frequent.
• The noise on the video only occurs at low speed - less than 10mph. And it doesn't occur when driving in a straight line - turn left or right and it happens.
• Above 10mph and below say 30mph you sometimes get a rumbling noise when cornering. Above 30mph, you wouldn't know there was a problem.
• The camera is pointing at the inner side of the rear off-side wheel - this does not mean that the noise is coming from there - in fact sounds more central (diff area!) but hard to tell.
• I've had the car since 2010 and has been utterly reliable. Dealer maintained, low mileage @ 83k.

Hi,
Thanks for responses so far.

I'll see if I can save the upload to a different format but this site is quite restricted on what you can upload unfortunately. Hence I've had to compress (zip) it. If you click on it it should unzip and be playable??

I'd agree it sounds like something rotational. A dry bush or bearing perhaps??

Other information which could be useful:

• The noise is intermittent - it does not happen all the time. But it is getting gradually more frequent.
• The noise on the video only occurs at low speed - less than 10mph. And it doesn't occur when driving in a straight line - turn left or right and it happens.
• Above 10mph and below say 30mph you sometimes get a rumbling noise when cornering. Above 30mph, you wouldn't know there was a problem.
