felicello122 Posted June 1, 2013 Share Posted June 1, 2013 I got a 2000 rd with double frame Hendrickson/Mack air ride from factory. I need to change my cracked rear housings both off them are shot. I found a cutoff Mack air ride out of a ch. the ratios are the same. The differences are the ch one is 38,000 pounder, mine is a 44,000. Also the air ride in mine uses the tube from bag to bag vs the flat plate on the cutoff. I am wondering if the spring spacing is the same so I can just remove my rear with spring attached and slap in the ch ones, both of my carriers are worn out also. The cutoff has a rebuilt one in the rear, I am going to take a chance with the front one. I don't need the heavy specs in the truck, never load it pass 80,000. Plus the 38,000 will be cheaper to maintain and lighten it up a little, worst come the worst I will have to buy all new u bolts, I would hate to mess with them because they are all nice and straight and tight, no signs of leaking.

RowdyRebel Posted June 2, 2013 Share Posted June 2, 2013 I had a cracked housing a few years ago....welded it up myself and it's doing just fine. Wasn't really all that tough to do (and would be easier now...bought a bigger welder since then)....just time consuming tearing it all apart and putting it back together again.

felicello122 Posted June 2, 2013 Author Share Posted June 2, 2013 If do all that work I think I will just swap them out, if it was only one maybe but they have been welded to many times. Quote Link to comment Share on other sites More sharing options...
felicello122 Posted June 29, 2013 Author Share Posted June 29, 2013 well the switch is complete, if anyone ever does this the air bags are different. the bags from the flate plate design will fit the cast frame plates, I used an exstension on the air line and used one nut, the other bag uses 2 studs.the springs lined up and I changed the top torsion bars and brackets.
