knocking from right rear area

Change left to right is much better from the safty point of view.and you have the same condition on the other parts of the suspension. Preloads etc.

Thanks guys. I already removed both from the car and a friend (and trustworthy restorer for 50 years) checked them on the bench. Both were not like new as can be expected but there was little difference between them? He also recommended to swap them and I am part way through that. I will report the result.

It is common to find free play at the rear antiroll bar: check the "cotton reel" like bushes with the wheels on the ground, Andrea

Well folks it's anticlamax time and proof that my first diagnosis was correct but badly investigated. After swapping the shocks over and driving the car it was the same, however a passenger managed to identify more clearly where the noise was coming from. Putting the car on a lift and shaking the exhaust it was obvious that the transverse box was colliding with the stabiliser rod mounting (which is actually on the left of the car and not the right !). Adjustments to the exhaust mountings fixed the problem. Thanks to everyone who took the time to offer advice.

Hi Bryan,
Pleased to hear you've sorted your problem.
I had a similar problem with my Series 1 2c Berlina, I thought at first that it was something loose in the boot, but emptying the boot soon disproved that one, I also thought it might be a shock absorber bush but when I put her up in the air on axle stands and lowered the axle, I very quickly found that the left hand side silentbloc bush in the panhard rod had completely disintegrated, the pin is a bit hard to hold as there are only two flats to put a spanner on while undoing the nuts.
A new pair of silentbloc bushes and new pins with nuts were obtained from Omicron at what I thought was a very reasonable cost, and a local small garage pushed out the old bushes out and pressed in the new for £10.
Don't forget to reuse the thick washers under the nuts as I didn't get new ones and reused the old.
I was tempted to only change one silentbloc bush as the other one looked perfectly OK, but as it was 50 years old it would have been false economy, Elizabeth said have two and if you only use one send the other one back for credit, when the garage pushed the bushes out the old one it fell apart, so it was a good call.
I know we tend to adjust to conditions but I'm amazed how much better the rear end seems to be controlled, someone did say recently that she rolled a lot when seen from behind when cornering, which I didn't think was a problem, I now realise that they were right.

Hi Brian,
Nice to hear that you could solve your problem without spending too much. I could kick myself for not following through my first diagnosis but without it I wouldn't have learned about M. De Carbon and his invention. I still wonder at the elegance of the engineering of our cars and despite some of the problems of keeping an old car going, they are a delight tp drive. I've owned mine now for 30 years and it still brings a smile to my face.

Hi Bryan,
I haven't had my 2c as long as your Fulvia, although I've had mine 19 years, but back on the road since November 1999.
I've never had De Carbons on my 2c, but I put a set of Armstrong on about 2000, and I've been happy with them.
Considering I have effectively the smallest engine in the heaviest car, my 2c has been great, even through the mountains on the Fulvia Knights Rallye in 2013, she is a bit slow going up but other than that she didn't have problems keeping up with all the larger engine, and lighter bodied coupes and Zagato examples.
