Just for peoples information really. Had a strange knocking from under my 2010 CR-V (Petrol Auto). Noticeable when lifting off the throttle. At first I thought it my be a UJ going, or even something wrong with the diffs! A friend said it might be a engine mount lose or the exhaust not being correctly fitted. So, if anyone has a similar issue try the D- Bushes on the anti roll bar, they are about £12 each for the part, and I have seen a YouTube video on how to change them. My garage tightened them up and the noise has gone.
