The type of column ("large" or "small" diameter, 36 or 48 splines) indicates the diameter of/number of splines on the section the steering wheel fits to, and determines which wheels can be fitted to which vehicles without changing the column. Other wheel types can be fitted by changing the column to the required type.

Small diameter (36 spline) column type wheels (types A and C) are interchangeable, similar large diameter (48 spline) column type wheels (types B and D) are interchangeable.

Please note that type C and type D wheels are visually identical, you need to count the splines or know exactly what vehicle it was removed from to tell them apart.

Type B+DSC and D+DSC were fitted to 2015/2016 model year Defenders when the DSC traction control system was fitted. These wheels have a different indicator cancelling arrangement and drive system for the steering angle sensor.

 

36 spline column wheels

Any small diameter column wheel can be changed for any other small diameter column wheel.

Wheel types A and C are also available in leather covered versions, and have the same fitment as the standard plastic wheel.

48 spline column wheels

Any large diameter column wheel can be changed for any other large diameter column wheel.

Note 1: Since the introduction of the 'Puma' engined Defender (2007) there is additional wheel variant used by Land Rover. This is a wheel which looks like 'Type C' but which fits the large diameter (48 spline) column. Fitment of this "Type D" wheel started part way through the 2008 model year as below. So this "Type D" Station Wagon-type wheel will fit Tdi Defenders and Td5/Puma hard tops, pick ups and soft tops with the 48 spline column. But if you are looking to buy a wheel please make sure you confirm which type of column it is for.
Note 2: The 2015 and 2016 model year Defenders (fitted with Dynamic Stability Control [DSC] use a different indicator cancelling arrangement using sockets in the wheel rather than prongs. This is for compatibility with the steering angle sensor fitted to these Defenders. These wheels are 48 spline fitment and visually the same as the type B and type D wheels. I have called these B+DSC and D+DSC in the table below. It may be possible to fabricate an indicator cancelling part to fit older vehicles, but this is NOT confirmed. As above, make sure you know what you are buying.
