Straydog954 Posted November 7, 2023 Share Posted November 7, 2023 Hello everyone. Looking at a 44k cutoff with the rubber bushing instead of the brass. Is one as good as the other or what is the main difference? My truck has the brass / bronze whatever it is Quote Link to comment Share on other sites More sharing options...
terry Posted November 7, 2023 Share Posted November 7, 2023 Can you post some pics. Of the 44 cutoff? Terry Quote Link to comment Share on other sites More sharing options...
mechohaulic Posted November 7, 2023 Share Posted November 7, 2023 besides the $$$ main difference is ::what is the unit going to be used for. ??? bronze/ brass always better then rubber . even in the "dinosaur days" cam bushings were bronze vs plastic. maintenance also plays a major part in vehicle set up.

Straydog954 Posted November 7, 2023 Author Share Posted November 7, 2023 Don’t have any pics. Doesn’t have the caps like mine. Ran vin thru Mack dealer they said 44k rubber bushed. It would be used in a tandem dump. Was wondering what the major differences are in one over the other. Quote Link to comment Share on other sites More sharing options...
terry Posted November 8, 2023 Share Posted November 8, 2023 Is it a camel back suspension? Terry Quote Link to comment Share on other sites More sharing options...
D-Day Posted November 8, 2023 Share Posted November 8, 2023 I have not seen 44 rears set up with soft bushings before but I can see it would not be to bad with a good set of polyurethane bushings if your not loading heavy regularly and maxing out the trunion shaft is the same diameter for the 38 and 44 but the axle housings can be heavier for the 44,000 check the rear right side of the housing for number code stamp for the axle housing rating Quote Link to comment Share on other sites More sharing options...
Straydog954 Posted November 8, 2023 Author Share Posted November 8, 2023 Yes camelback suspension. Dealer said they did come rubber bushed in 44k idk. Frame is doubled if that says anything. Quote Link to comment Share on other sites More sharing options...
JoeH Posted November 8, 2023 Share Posted November 8, 2023 Sideways torque arm? Rubber doesn't have as much resistance to keep spring packs straight, so your axles will tend to wander more. We have a truck with 38k rubber bushed camelback and the tires will wander as much as 6 inches out of alignment backing up in turns. Truck doesn't take long to hit this point after putting new bushings in. Quote Link to comment Share on other sites More sharing options...
Straydog954 Posted November 8, 2023 Author Share Posted November 8, 2023 Can these suspensions be converted to the bronze bushing and keep the same housings and springs or no? Quote Link to comment Share on other sites More sharing options...
terry Posted November 8, 2023 Share Posted November 8, 2023 I’m thinking no the bronze bushing spindle I believe is threaded on the end and I don’t know if the 44K rubber bushing has any threads. Terry Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted November 8, 2023 Share Posted November 8, 2023 no threads, need a new trunion.. 1 Quote Link to comment Share on other sites More sharing options...
Straydog954 Posted November 8, 2023 Author Share Posted November 8, 2023 Ok thanks. I’m gonna go a different route. I’m always running heavy gonna find a bronze bushed setup. Quote Link to comment Share on other sites More sharing options...
