Hi List,
 
I've felt fairly bad for a couple of days about one of my replies to the  
highway speeds/diff/pumpkin thread but it's taken until now for me to find 
the  time to try and put things right.  To serve my 'penance' I've finally  
gotten round to doing what I should have done in the first place which is dig 
a  complete final drive assembly from under the bench in my garage, pull it 
apart,  and photograph it.
 
As you can see in both photos, there are 2 components.  The  
differential/diff is dark metal and has a bearing on at each end.  This  differential also 
has a Phantom Grip device fitted to it (another  story/thread).  More 
importantly this diff also has the crownwheel or ring  gear bolted to it.  
However, it needs the pinion to go with it to make a  final drive unit and the two 
items are matched components.  
 
It is possible to buy just the final drive gears - the ring and pinion by  
themselves without the diff - you can find them on ebay.  But, it's rare to  
see a diff with the ring bolted to it and the pinion with it as another  
part.
 
In the photo you can also see the differential carrier itself which for the 
 Sprite/Midget is light in colour because it's cast from aluminium alloy.   
You can also see looking inside the diff carrier the pinion gear.  
 
So, the easiest way to swap the final drive ratio (4.22 to 3/9) is to buy a 
 complete final drive assembly which is: the diff, the ring and pinion and 
the  diff carrier.  If you just buy the diff which goes into the pumpkin and 
 even it has the ring gear bolted to it, it won't work in your pumpkin 
(final  drive assembly) because the pinion will have the wrong tooth count for 
the new  ring gear being a different ratio (eg: 9 teeth instead of 10 teeth)
 
Sorry, apologies to the list if my earlier reply was rude and  discourteous.
 
Regards
 
Daniel

You mean we should just R&R the 3rd member, right?
