Discovery 1 Halfshaft - Front
There are two different types of halfshaft/C.V. joint assembly: Up to VIN JA032850 (1992), drive is conveyed from the differential via a 10 spline halfshaft, which engages into a C.V. joint inside the swivel housing. Drive is then transmitted through a seperate outer shaft (known as the 'driving member'), which engages in the C.V. joint at its inner end and bolts to the wheel hub at its outer end.
From VIN JA032851, a halfshaft is employed, as before (either 10 or 24 spline), but the C.V. joint/shaft is splined to engage in the outer hub, thereby transmitting drive.
Vehicles with ABS employ the later type of combined C.V. joint/shaft. However, ABS assemblies are not interchangeable with non-ABS.
