rasmith1 Posted November 19, 2011 Author Share Posted November 19, 2011 Thanks Rob. I called a mack dealer and they told me they was 44s because it didn't have the rubber bushings in the Trunnion cause mine has the cap with grease fitting on it.

I have two trucks with SWDL56 rears and they are both 34,000# suspensions with aluminum brake chamber mounts.Most rears I've seen with the cap and grease zerks are 44,000# or greater.Hope I've not mislead you.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

Back in late 70s early 80s at the old Blue & White truckstop just north of Indianapolis,IN i saw a KW conv. pulling a dump trailer with Mack rears wander if it was the same truck.
