Land Rover is one of the oldest four wheel drive vehicles in the world entreating into production in 1948. Since that time, the British automaker has produced many models of this SUVs including the third generation LR3. Produced from 2004 to 2009, the third generation Discovery 3 is valued by its owners, however, they have been known to experience mechanical difficulties from time to time.
One problem that owners of these sports utility vehicles have reported is an issue with the rear differential. Sometimes this failure in the differential can result after only 20,000 miles and sometimes they don't fail until over three times the mileage. Changing the fluid in both the rear and front differentials is an important first step, but if the problem persists then the solution is to bring it in for a proper inspection by a trained professional.
While some wear and tear on differential clutches is to be expected, especially if the vehicle is being used in a true off-road capacity, repair can be quiet expensive. Unfortunately, this is an issue that needs to be addressed and one that will probably require the help of a trained mechanic.
If you are experiencing a rear differential issue with your Discovery 3, you should not hesitate to bring it in to a local Land Rover service expert for a complete repair diagnosis. They will be able to provide you with an estimate that will likely be much cheaper than what a dealership can offer you.
