Rear Suspension Bearings

[Guest chrisbee]

Hi, my 2001 2.2 estate (100,00 miles) has suddenly developed a loud metalic knock when driving on normal road surfaces. I've had a quick look underneath and can't see an obvious problem. I suspect it may be the suspension bearings. Would they fail suddenly without warning (there's been no creaking or groaning) and how can I check them?

 

All help wellcome!

Raise the suspension. Stand a way from the back of the car and look at the wheels. If the tops of the wheels are sloping inwards /------\ then you need to replace the arm bearings.
