I-asi yangasemva yi-Heavy Duty Truck AC16 type parallel duplex drive axle, i-asi ithatha i-asi enkulu ye-asi yokuphosa igobolondo, kunye ne-axle ephezulu yokuthwala i-asi enye ziitoni ezili-16. Ulwakhiwo olunomlinganiselo wesantya se-5.45, kunye nombindi we-helical bevel gear main decelerator kunye newheelside planetary decelerator zenza ukuhla okuphindwe kabini ukunyusa i-torsion, kwaye kwangaxeshanye inokuphucula ukucocwa komhlaba kwe-asi.
Zombini ii-asi zangaphambili ze-Howo 7 ilori yokulahla i-axle enzima luhlobo lwe-HF9 olusezantsi oluhamba phambili lwe-asi ye-Heavy Duty Truck, kunye nomthwalo omnye we-asi we-9 yeetoni, ezihambelana ne-10-bolt yamavili entsimbi kunye ne-12.00R20 uhlobo lwamatayara ensimbi yentsimbi kwiilori zokwakha.Ipompo esezantsi yebhuleki ibonelelwa nguWilburco kukhuseleko oluthembekileyo lokuqhobosha.Iyonke ilori ithatha iziqhoboshi zegubu kunye negumbi eliphindwe kabini legumbi lomoya, kwaye ububanzi bezihlangu zebrake kwi-axle yangasemva bunokufikelela kwi-220mm, kwaye uxinzelelo lomoya we-brake yi-0.8Mpa, kunye nokusebenza kakuhle kwe-braking.Imeko yendawo yokwakha imbi kakhulu, inothuli, umgangatho womoya ophantsi, ngoko ke isithuthi samkela izihluzi zomoya kabini, ukungena emoyeni kwi-air filter yephepha kuya kuhluzwa phambi kwe-oyile yokucoca umoya, ukuze kuqinisekiswe ukuba injini inxaxheba ekutshisweni komoya unyulu ngakumbi.
