Michigan | Ive got a 1985 volvo white cabover semi tractor with a 3208 cat motor.the tractor runs great with lots of power to pull a 32ft tandam trailer with a 9ft spread.The problem is when starting off down the road the front/ cab axle area will start to ''HOP''at around 45mph and then level off around 50-55 it does it empty or loaded and slowing down also, always around the same mph range.Ive had all axle's off the ground and spun the tires to look for any'' wobble''but everything seem in order.new shocks in front and even one new steer tire made zero difference....any thoughts or sugjestions? | |
