BMW X3 Differential

The BMW X3 Differential allows each drive wheel to rotate at the speed it requires to enable the compact SUV to corner smoothly and maintain traction. In the case of modern models of BMW X3, it is mounted between the driven axles and distributes the torque through a gear set, preventing the tires from scrubbing in turns and easing the stress on the drivetrain. Early X3 versions were based on an open Differential, a basic cluster of bevel gears, which splits the engine power equally but can send almost all of the torque to the wheel that loses its grip on wet or icy patches. Later versions in the BMW family introduced a limited slip Differential, adding clutch packs and spring pressure to vary the power flow to the wheel with better traction, improving pull away from bends and light off-road tracks. Both of these styles share the requirement of a clean lubricant, as heat, pressure, and moisture can thin the lubricant and help wear it out more quickly, and this Differential may become noisy if levels get too low. Regular Differential checks every 3,000 miles help the BMW badge retain its poised X3 handling and save owners from costly repairs.

Q:
How to remove and reinstall the front differential and drive axles on BMW X3?
Posted by Serge M.
A:
Lift up the car and deflate the front tyre, dismantle the under floor tray protector and front end cross member. Remove the front axle differential oil with the specifications stated above and then remove the left drive axle then the right drive axle from the bearing pedestal, leave it to extend for 7 to 8 cm. Then, you should take out the front drive shaft, then unbolt and lower the differential paying a lot of attention to avoid dropping it. Before reinstalling the differential, replace the sealing O-ring between the oil pan and differential by installing a new one and coating a 1/4 inch of the inside edge with front differential oil. Return the differential to the oil pan, but do not forget the drive axle flange seal before fitting the drive axle; examine the differential oil level.
