how can stop constant rear knocking noise , on my vaux vectra, not the bus?

rear knocking noise from rear of your vectra is the rose bushes top and bottom arms that hold the hub in place are prone for going replace these and your problem will be solved in a flash . not the easiest to do but you can buy a puller that costs around 70 pound and the bushes are roughly 9 qiud each ... you need 4 ....
