Sport Wagon models
In order to provide a wide, ilat iloor in the cargo compartment,
the rear suspension on the Sport Wagon is unique to itself.
The shoclcabsorber is attached diagonally between the lower
swing arm and a mounting bracket on the subframe. The
spring on each side is mounted between a perch at the top oi
the wheel bearing carrier and the bottom of the cargo com-
partment floor.
Starting with 1999 Sporl Wagon models, a self-leveling air
suspension system with electronic height control (EHC) was
introduced. The system is standard on V-8 models and op-
tional on 6-cylinder models.
On models fitted with electronic height control (EHC) rear
suspension, the standard coil springs are replaced by air
springs. Air pressure in the air springs is automatically con-
trolled by the EHC system to compensate for ride height and
load variations.
