Customer Question

i have an insignia 4*4 and i am getting a knocking noise similar to a faulty drop link. the local garage cannot find anything wrong. the noise is quite pronounced on uneven services. is there a test jig that the car can be hooked upto to isolate where the knocking is coming from?

Hopefully i can help..

Normally droplinks/antiroll bar bushes are very common issues like on these cars...the only thing you could maybe try or phone around to see if any garages local to you - have a ramp fitted with suspension shaker may look violent when its on there but it can help determine problems/ecess movement on suspension..most MOT stations would have them and should or may help narrow down any sort of movement in the suspension bushings/antiroll bar.
