Update Note: 2004 has CDL as factory option.

In the factories to eliminate driver decision the Discovery II is imported to the US without a differential lock (CDL).

The Rover Discovery is the only in its class that does not a CDL. The CDL is standard on the Land G wagon, Trooper, H2, Grand and Montero.

The omission of a CDL is a serious flaw, and to poor off-highway performance and damages the trail. The vehicle a 4 channel traction control to distribute power to the drive which works well in sand and mud, but creates a liability when the vehicle is in rough, rocky, uneven The systems design does not power to the tire with until after the low-traction begins spinning.

This method of 4wd is rough on the (tires, brakes, etc.) and damaging to the trail, which is a conflict to tread-lightly principles. In this system is dangerous. I experienced three major with this system driving in extreme terrain:

1. driving downhill, or backing a hill using engine braking, the vehicle will when ANY tire leaves the as there is not a physical connection the front and rear axles

2. When Backing Down a the lack of a CDL allows the front to lock-up (because of the weight related to the angle of decent). In situations this can cause the front end to slide sideways, in its to follow gravity (remember, the wheels are locked. A skidding has little traction) The vehicle sideways on a hill can result in a

3. The vehicle will rock a tire (or tires) are off the ground, as the control system attempts to power to the stationary tires. can unsettle the vehicle, and cause a of control.


1999-Mid. 2001 have the CDL, but no linkage to engage it. There is a 10mm on the top of the front driveshaft output. are several companies that can a solution, including:

Land North America can provide you the parts to use the 2004 linkage.

2001-2003: These Discoveries no 10mm stud to use for engaging the CDL and a complete replacement of the front section of the transfercase. This job has done by: Bill’s European in Fe, NM
