ABSTRACT:
An improved, light-weight left axle wheel assembly attached to the frame of a load carrying vehicle, used to increase the capacity, performance and safety of the vehicle. The left axle wheel assembly has a pair of inflatable airbags for alternately raising or lowering an attached pair of wheels and tires. The left axle wheel assembly has a pair of resilient bushings that dampen and reduce the transfer into the vehicle frame of the torque and stress caused when the tires traverse uneven terrain such as curbs. The assembly also has a pair of caster adjusting torque arms mounted at oblique angles with respect to the vehicle frame and each other that also help to reduce the transfer of torque and stress into the vehicle frame.
