Anyone know about Compliance Bushes?

Over the past few days the TF was at the garage to source a knocking at the rear. The garage, inspected the underneath etc and deemed all was in order, all bushes etc were in good condition but couldnt find the source of the knocking.

We test drove the car together and agreed the noise was coming from both sides. The noise can be heard on small bumps, doesnt need to be speed humps etc. The noise is not clunking or a heavy noise if you know what I mean.

As nothing is showing as failed bushes etc mechanic thinks it may be the rear shockers as the noise it at both sides. We decided to wait and see if it gets worse or if the source becomes more evident.

It's been suggested by a couple of TF owners the complaince bushes may be at fault. Maybe the mechanic has missed them or they are difficult to see? anyway my question is, would failing (or failed ) compliance bushes give this low level knocking noise on minor bumps?

Compliance bush of one of the trailing arms were my first thought as well, as all the other links and bearings had been checked. They are a bit difficult to get to indeed.

Another possible culprit could be one or both of the rubber mountings for the backbox hangers. One of them is quite worn on my F and this generates funny noises, too. You can check this by simply moving the tailpipes up and down.

On my old F I hat a rattle coming from the rear end, and it turned out to be a knackered cat, the ceramic bit inside was completely loose and reduced to the size of a small bread roll.

Thanks for the replies. Im sure the problem sits withthe shockers or the compliance bushes so I'll try this weekend, weather permitting, to have a look underneath but eventually it will need to go back to the garage for further investigation.
