Hey there guy's i know there is alot of post's on knocking and wha tnot but need abit of help pin pointing or solving my problem. Seem to be if i go over speed bump's at a angle and the cab rock's side to side i got a knocking seem's the be from the rear although i could be wrong. If i hit them straight on no knock, also if i steer left & right sharpish and get the cab rocking i get the knock... I know there's a slight ace bar leak to the rear but its doing my head in now & its 2008 tdv8 no warranty...

Thanks Jamie

I have the same fault mate. Did you find a fix?

Probably ARB 'D' bushes or links. Rock the car does it knock then ? If so you need it over a pit or on a 4 poster ramp to identify which bushes or links. 2008 G4 RRSport TDV8 current
2009 TDCi 90 current

There are a couple on here (myself included) for whom the knock from the rear is the chassis dampeners swinging and hitting the (modified/aftermarket) exhaust. Worth a look and cheap to test/fix.

Cheers. Every home should have one!
