What it means (if you find this fault)
A knocking noise from the suspension usually indicates that a rear suspension arm needs replacing
ebay dude said:When surveying Fiat mechanics, they recommend that quite often, the entire arm needs replacing. As the guide is a buyers guide, we make people aware of the worst case. They can then go to a garage to get a precise quote and diagnosis. I appreciate you making contact becasue we can get innacurate information and we like to continually improve, but your writing was rude, which is unnecessary.
