This all depends on whether the 2005 Focus is a Mark 1 or Mark 2 version of the Focus. So that's the first thing to ascertain. If they're both Mark 2 cars, then there's a very good chance that the boot release will be the same in either (and, therefore, interchangeable) as we're talking about the same car.

But even if the 2005 Focus is a Mark 1 model, it would still be worth physically checking to see if the release latches are the same. That's because even though the Mark 1 and Mark 2 Focuses were different cars, many manufacturers (Ford included) carried over some mechanical parts (such as latches and cables) from previous models to save on development costs. A good example of Ford doing this was the succession of 1980s Falcons including the XD, XE and XF models which all used the same exterior door handles. So compare the latch you have with the latch on offer and make sure it operates in the same way and direction, uses the same mounting points and will connect to the same cable. If so, you might just be lucky.

Ford replaced the Mark 1 Focus with the Mark 2 in June 2005, so interchangeability would depend on the build date of the 2005 Focus you have. While the Mark 1 and Mark 2 Focus both offered a two-litre four-cylinder engine (among others) the two engines were from different engine families. The earlier car used a member of the Zetec family, while the Mark 2 Focus two litre was from the Duratec family.

So, unless both Focuses are Mark 2 cars, there's very little chance of sharing things like intake manifolds, even if the spark plugs and ignition systems could be swapped between Mark 1 and Mark 2 cars.

Not really sure what the axles have to do with a tyre that has jumped ship, but perhaps you mean the whole front wheel and tyre assembly came adrift. If so, you’re lucky not to have crashed or hurt yourself or somebody else. If this was caused by a broken axle (also called a driveshaft) then perhaps that’s the basis of your question.

However, the answer is probably no; the driveshafts from a 2002 and 2006 Focus are unlikely to be interchangeable. Even though the engines and gearboxes form each of these two Focus models were similar, the later car was 141mm wider, which almost certainly means it had longer driveshafts than the earlier car. But if a replacement driveshaft is what you need to get back on the road, I wouldn’t have thought finding one from a 2006 Focus (the same as yours) would be such a problem. Parts recyclers are likely to have plenty of these cars in stock, and specialist driveshaft shops can be a great source of spare parts also.
