The Discovery's front axle is an extremely rugged beam axle design, comprising a one piece steel tube with a separate cast steel differential housing.
All of the component parts of the axle, such as the differential assembly, halfshafts and C.V. joints, can be removed and replaced with the axle in situ. It is rare for a vehicle to require a complete replacement axle and for this reason we have avoided listing full axle assemblies. Nevertheless, if you should require a complete unit, please contact our sales department for price & availability (remembering to quote the year and VIN number of your vehicle, along with the serial number of the axle).
D.I.Y. overhaul of the differential assembly is not really viable, due to the specialist tools and skills required, so we have listed complete differential assemblies, both new and reconditioned.
The serial number of the front axle is stamped on the front or top of the axle casing, on the left hand side (roughly in line with the axle breather).
Serial numbers comprise a 3-figure code, identifying the axle type, followed by the serial number and then a suffix letter (A, B or C).
The final drive ratio for all models is 3.54:1.
ABS was introduced in March 1994 for the 1995 model year (VIN MA), necessitating some changes to the front halfshafts and C.V joints. In order to simplify this complicated area, we have divided the relevant parts into two categories: non-ABS vehicles and ABS-equipped vehicles. It is important to bear this in mind when ordering parts, due to the safety-critical nature of ABS-related components.

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 separate 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 into which it engages now incorporates the outer shaft as one complete assembly. The outer end of 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.
