The front axle looks pretty much untouched. If you wanted to make 100% sure you'd have to open it up to replace the hub seal and wheel bearing grease, but I do doubt that the heat would have penetrated the metal components enough to have caused any damage.
The engine has got seriously hot, the auto box was bolted to the back of it, and apart from some blackening due to smoke, you wouldn't even know that it had been in the fire. The torque converter looked untouched. We also had to open it up to fit the throttle position sensor, and the oil was in perfect condition. The heat went up, so the boxes and axles seem to have survived almost untouched.
Unfortunately I had to be in East London for 1am, otherwise I'd have stayed another day and used the crane to strip the axles off of GW, and if needed slot them under the silver 80, complete with the suspension.
In reality it's six of one and half a dozen of the other, Chris has experience of stripping and rebuilding 80 axles, so he could have the axles on the silver 80 all sorted in a pretty quick time anyway. The silver one has such low miles that it shouldn't be worn out, it's just stood a long time, and had some monkeys doing some 'improvised' servicing on it!
Either way, it's going to end up being one sweet truck.
