Knocking noise, Im at my wits end - please help
Posted: Tue Feb 16, 2016 9:27 am
I would appreciate any suggestion here, this is driving myself and the mechanic to murder.
The vehicle: Gen3 2006 LWB 3.2 GLS 165k km - No modifications
Recently it developed a knocking noise from the front. This happens when one brakes (one solid 'thunk') or when you accelerate (again, one solid 'thunk')
The shock are the originals so I was planning on changing them anyway. Now I had a reason.
Sent it to a local indi
New shocks fitted (std KYB)
Upper ball joint on wishbones replaced.
Noise still there. Sent back.
As per the advise on this forum
The 4 (I think) little donut bushes on the Engine support cross member replaced. Noise still there.
Stabiliser bar drop links replaced. Noise still there.
Mechanic has gone over vehicle with a crow bar and cannot find anything else that is overly loose.
Noise seems to only happen with fore/aft movement of the engine. I am also noting it when turning at parking speed.
If it was engine mountings, Im sure you would hear it just revving the engine.
Its not a rattle like brake calipers. I did the last set of brake pads and know that all the anti rattle springs are in place.
Suggestions please.
