The locking center differential was still fitted although the actual mechanism linkage was not on the early series 2 production, as Land Rover believed that the traction control system [TCS] and newly developed Hill Descent Control system [HDC] would render it redundant. before then being fully reinstated (with the linkage) on the facelift model in 2002, as a cost option (although standard equipment on high spec vehicles) Whilst the traction control system worked very effectively, it did not offer the same level of control and smooth operation as the vehicles fitted with the differential lock. Customer demand saw the diff lock controls fully reinstated on UK and Irish models, and aftermarket kits are offered by several vendors for those vehicles which were produced with the lock, but not the linkage.
