A 3 -degree difference in the SAI angle on each side ofthe front suspension may cause a FWD vehicle tohave increased __ during hard acceleration.
Technician A says that on FWD vehicles, the front wheels toe-out while the rear wheels on an independent suspension try to toe-in as the vehicle moves ahead. Technician B says that on RWD vehicles, the front wheels tend to toe-in while the rear wheels toe-out in response to rolling resistance as suspension compliance. Who is correct?
explain the concept of the virtual steering axis compared to traditional suspension
