vinny933 Posted May 23, 2019 Share Posted May 23, 2019 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 Quote Link to comment https://www.bigmacktrucks.com/topic/57354-2019-mack-triaxle-dump-rattle-since-new/ Share on other sites More sharing options...
vinny933 Posted May 23, 2019 Author Share Posted May 23, 2019 Yes number 7 I can stick my finger in there and move them truck is new 10000 miles on it Quote Link to comment https://www.bigmacktrucks.com/topic/57354-2019-mack-triaxle-dump-rattle-since-new/#findComment-423537 Share on other sites More sharing options...
JoeH Posted May 23, 2019 Share Posted May 23, 2019 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.

JoeH Posted May 24, 2019 Share Posted May 24, 2019 Didn't know there were 46k camels. 38, 44, 55, 68, 80, is what I thought there were Quote Link to comment https://www.bigmacktrucks.com/topic/57354-2019-mack-triaxle-dump-rattle-since-new/#findComment-423586 Share on other sites More sharing options...
JoeH Posted May 24, 2019 Share Posted May 24, 2019 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.

JoeH Posted May 24, 2019 Share Posted May 24, 2019 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.....
