new to ther forum
i have a problem with my vectra 2004 ls dti 2.0 it has 167000 miles and is in good condition considering miles
but rumles only when acclerating
the rumbling sounds as if its coming somewerte from the passenger side
the rumbling isnt that noticable at low speeds but gets considerably worse as the car speeds over 40 mph
sent it to the garage and the advised i replace the cv joint and driveshaft costing me £155 pound which i paid and nothing changed
he the told me it could be the gearbox mount but havnt got this replace yet

anyone got any ideas what this problem might be
