knocking on rear
 

i have just brought the car and have seen that mot advisory said offside rear anti roll bar linkage has play.my mechanical knowledge is ok so is this a fairly easy job and rough cost of parts?thanks

If its your rear drop link then yeah dead easy to do m8. only 2 bolts.

Have a look here:
