The rear suspension is the “intragal” multi-link design taken from the E38/E39 vehicles. Several components AER made from aluminum to erduce the unsprung weight. The X5 with the M62TU engine uses the EHC (air spring) suspension system. The EHC functions the same as the E39 Sport Wagon with only minor differences to the components and lay- out of the system. The X5 with the M54 engine will use standard springs in the rear with the EHC system as an option. The rear struts on the X5 are mounted to the body instead of the sub-frame.
The rear axle sub-frame is mounted to the body through four bushings (larger than E38) for increased load and comfort. The rear differential is mounted through three rubber bushings two in the front and one hydromount in the rear. The wheel bearings are similar to the E39 but incorporate different seals - designed for off-road use.
