After replacing my dogbone mount (old one was completely shot after removal and inspection) this morning to try and eliminate the vibration coming through the car on hard acceleration, I still have a certain amount of vibration coming through the car (and a little knock if you let off and plant the throttle again) and it seems like another mount may be to blame. Going to try replacing the lower (gearbox) mount tomorrow but if there's still movement I suspect the top mount needs doing too. Question is: if it is the top mount which half if most likely to have failed? Is it the part on the inner wing or the part bolted to the cylinder head?
