In 2016 - the B20 had a problem. The front suspension wasn't quite right. It had been rebuilt some years back, but the parts weren't available to do it right, and the suspension would "clunk" badly on one side with dips or holes. It made driving frustrating, as one had to steer around road conditions, and then brace for the inevitable which would only happen when least expected. On smooth roads it wasn't a problem. But I live in a city, and the roads are lousy.
The options were limited: the knowledge base on the suspensions is limited to a few people - and while the local mechanic (Gianni at Autosprint in Chicago) was fully capable - as there is little he can't do - what he didn't have was any knowledge of what parts might be available. It would be a first time effort, and the car would be laid up while the communication went back and forth to Italy. Who knows if all the right parts and pieces would come together? The suspension, while not too difficult, has bits and pieces.
One thought was to send it to Italy - but there would be little communication possible about what to do - they tend to do what they think is right, and it would be shipped back. A fair amount of risk there.
In the end, conversations with Simon Thornley and Wayne Kelham were quite useful. They were fully committed to doing a full rebuild, and had just completed two s.2 B20 front suspensions in the past year. The sliding pillar has some slight variations over its lifespan on the Aurelia, and so their experience with the s.2 was useful. So too, they had been in good communication with Italy, about what new parts were available.
So Gianni and I pulled the front axle out of the car in my garage, put the car up on stands, and the axle on a pallet. After about 20 pages (and endless phone calls) the axle was shipped to Thornley Kelham. They undertook a full rebuild, doing a crack test on the hubs, and finding one of the steering arms needing replacement. They went deep into the suspension, found the corroded tabs (not functioning very well, source of problem), plus a number of very worn out parts. They got new ones from Italy, cleaned it all up, and put it back together, rebuilding the brakes at the same time. And just to be sure, they put the axle on Simon's own B20 for a road test.
The axle came back about 2 months after I shipped it to them, and was fitted right to the car. And the transformation was total - the ride in the front is not only supple, but controlled. Its a level of finesse that is just lovely. I had thought the standard for a good front end was our Appia with 60k original miles, but this was even better. Its been now two years since the work was done, and all is good!
Many thanks to Simon, Wayne, and the team at their shop. Job well done!
