I'm thinking of replacing the De Dion tube and the A-frame, as a precaution after 3 and a bit seasons of racing. Being a typical lazy git, I was wondering if it was possible to do this without dismantling the wheel hubs? Has anyone tried that? With my sensible head on, I reckon it isn't possible - once the De Dion is out then the driveshafts will fall out of the diff and make a huge mess, and the brake pipes will probably rupture and add to the mess. Then it will take ages to sort out and I won't have the car back together in time for Silverstone on the 13/th/14th. There is a little bit of me, though, that says you can support the hubs, release the brake pipes from the tube, undo the bolts carefully to release the De Dion from the ears (etc), then lift it and slide out carefully. Replacement is then the reverse of disassembly, as they say, and hey presto job done in a third of the time Has anyone tried this?
