roadusercharges Posted October 10, 2005 Share Posted October 10, 2005 were you going in reverse when it broke?, as my stub axle broke clean through the top kingpin bush, and the steering arm fell to the ground.Nigel Quote Link to comment Share on other sites More sharing options...
AutomaticMack Posted October 10, 2005 Share Posted October 10, 2005 I had the same problem 4 years ago! Maybe issues like this should be turned into the National Highway Safety Administration Quote Link to comment Share on other sites More sharing options...
fullfuel01 Posted October 11, 2005 Author Share Posted October 11, 2005 It's a cement truck, I was on the job (a luck) turning in an driveway to back up to the concrete pump. when i put it in forward and and the sterring wheel i heard a bid bang but the truck wasn't at the level so sometimes the truck akes this sound. I let the clutch come off and the engine stop... front wheels of the truck (12 wheelers) were not going the same place... still parked in the garage looking for that F..KING parts!!!

roadusercharges Posted October 12, 2005 Share Posted October 12, 2005 the new stub that i fitted had a different forging style to the one that broke, perhaps someone at Mack got their s*it together , It appears that going in reverse puts extra strain on the components, when u are going from lock to lock , let alone in soft going.nigel Quote Link to comment Share on other sites More sharing options...
