In a number of areas, I've found Defenders much easier to work on than US made 4x4's. Generally, if something is tough to work on in a D-90, it's tough to work on with any car. For instance, the front brake rotors. In almost all GM/Ford/Jeep with a Dana front axle, the rotors need to be put on a hydraulic press to separate them from the hubs. On a D-90, a 12pt socket and breaker bar is all you need.
