Read complaints for MACK CXU (2009)
My coworker was changing the oil on a 2009 mack and i happened to notice that the 5th wheel plate was shifting around on the frame. I applied a box end wrench to the mount bolts and discovered that all ten of the fasteners holding the 5th wheel to the frame could be turned easily using one hand. That is not my idea of being securely attached! no action was taken on this truck because it was time to go home and if the boss doesn't care and mack doesn't care what can i do except complain to the federal government that mack is using substandard bolts in the assembly of their trucks! the 5th wheels are loose. Management doesn't want to know! be very afraid on the highways my fellow americans, you are more likely to die from a truck accident than you are from a terrorist attack!
Some of the 2008, many of the 2009, and almost all of the 2010 model mack trucks used by abf freight system were built and delivered with weak bolts holding the 5th wheel coupler to the frame.on 27 sept 2010, unit 19212 was in the shop for routine repairs. A mechanic noticed that all of the bolts on the right side were loose enough to rattle in their holes and that the coupler was sliding around on the frame. The manager instructed us to tighten the bolts and not to replace any unless they stretched. All of the bolts stretched. All were replaced.
On tuesday, july 19 of 2011, i observed that the 5th wheel bolts on abf unit number 19223 were loose enough to be turned by hand. The bolts are not being interfered with by the huck rivets below them. The nuts are prevailing torque lock nuts and are not loose on the bolts. The bolts have stretched under load. I was going to show the unit to the director of maintenance, who happened to be in our shop that day. Unfortunately, unit 19223 was sent out before i could show him. I did, however, make a video of me turning the loose bolt by hand. This is only one of hundreds of abf macks from 2009 and 2010 that have 5th wheel bolts that are yielding under load.
