2019 mack triaxle dump rattle since new

Recommended Posts

ok I think I found the rattle  its a camel back suspension and it has  the side pieces on each side of the spring inside the boxes, not sure what you call them but there bouncing up and down on the insulators. is this common should I bitch to mack or is there something I can put in there to stop it, first thought was spray foam but that's cheesy 

 thanks vinny

They probably installed wrong size ones, from a lighter Camelback. I'd bitch because it's a new truck. Older versions of Camelback don't use them. Our 79 R model doesn't use those #7 or the sideways torque arm to the frame. Has rubber trunion bushings and the axles walk as much as 8 inchs out of alignment from each other.

Didn't know there were 46k camels. 38, 44, 55, 68, 80, is what I thought there were

They're not hard to replace, but they take big guns and floor jacks, and a BA torque wrench. Because it's got a warranty from manufacturer defects I'd make them do it.

If the dealers going to give you the BS run around then squirt some caulk or foam in there and call it a day. Wonder if the insulator pads the factory put in are even the right size. Maybe they used some from the 38k rears.....
