gearhead204 Posted September 27, 2016 Share Posted September 27, 2016 I take it we are talking about "camel back" suspension, what application is the truck being used for? on road or off? have any of the springs ever been replaced? Quote Link to comment Share on other sites More sharing options...
Mackpro Posted September 27, 2016 Share Posted September 27, 2016 Did you go with rubber pads or upgrade to urethane? We always use the urethane pads for any truck with a 3rd/lift axle. We get the urethane pads direct from Mack. 1 Quote Link to comment Share on other sites More sharing options...
theakerstwo Posted September 27, 2016 Share Posted September 27, 2016 I run two lift axles and rubber will not stay with you. Rubber pads now is not same as they were 45 years ago. Quote glenn akers Link to comment Share on other sites More sharing options...

gearhead204 Posted September 28, 2016 Share Posted September 28, 2016 seems like their is several spring length's if I'm thinking correctly just wondering if wrong one got installed? Quote Link to comment Share on other sites More sharing options...

Rubber pads now is not same as they were 45 years ago. In the days of Mack Trucks, we sourced our trunnion pads (and all rubber insulators) from a quality supplier called Lord. http://www.lord.com/industries/commercial-vehicles/truck/cab-suspension However, I suspect Volvo long ago shifted to a cheaper supplier.

theakerstwo Posted September 28, 2016 Share Posted September 28, 2016 Your right again. I have taken pads out of trucks that were ten years old and the pads were still useable. Quote glenn akers Link to comment Share on other sites More sharing options...
kscarbel2 Posted September 28, 2016 Share Posted September 28, 2016 I like the 10QK388 urethane lower pads for vocational applications, but felt the softer rubber 10QK36B was better for most on-highway. Quote Link to comment Share on other sites More sharing options...
j hancock Posted September 28, 2016 Share Posted September 28, 2016 Are you using the insulator spacer blocks in the spring boxes? Has the wheelbase been checked between the front rear axle and the rear rear axle? There are offset spring end pads made to compensate so each side will be reasonable close in measurement. Especially if rubber spring end pads are bring used, the blocks are to be installed lubricated with soap NOT grease. Who knows, maybe at some point, an incorrect length torque rod was installed. There are several lengths available. Here is a bogie alignment diagram. You will want to verify what the correct dimension values for your 2006 are in case they are different then the ones shown. 1 Quote JimIt doesn't cost anything to pay attention.
