Replaced the front anti-roll bar bushes 3/4 months ago which cured a persistent knocking when going over drop kerbs, potholes etc.
The knocking has however returned, worse than before and although there is some lateral movement of the anti-roll bar, enough to catch the underside I don't think that is the cause of the new problem. The movement is likely due to the removal of the plastic sleeves, so I'll have to get a couple of s/steel jubilee clips to stop that.
I've checked the suspension bushes which seem to be ok, the exhaust isn't catching anywhere so can anyone suggest what else could be loose and knocking?
