Hi everybody,
In need of some advice if anyone can help.
I have an unidentified knocking noise on the underneath of my 2004 3.0 Diesel Vogue.
This knocking can be heard very clearly at low speeds whilst travelling over uneven surfaces like a bumpy road etc, on the smooth flat complete silence.
I have recently had both rear N/S & O/S hub bushes replaced but can't find the cause of this knock.
I sounds like the exhaust knocking on the chassis that sort of noise only when going over a bumpy surface in rhythm with the suspension. After having the rear hub bushes changed due to the noisy squeak at my local indy dealer they checked underneath and couldn't find anything lose.
Any ideas folks, there is no transmission play, goes into gear smooth, air suspension all seems fine, no knocking under acceleration or breaking, fine on cornering both low or high speed, this knock seems to appear at low speeds on uneven surfaces.
