dave92cherokee Posted May 21, 2014 Share Posted May 21, 2014 D44 doesn't always mean MT, the 88 4wd pioneer swb i have had a 44 rear with the 3/1 pack in it and the 44 has the larger 10x2.5 brakes versus the 35 with the 9x1.75 brakes.The extra springs that are bolted to the top of the pack are just helper springs to aid in holding a higher load without bottoming out, or the springs were already sagging so they put them on as a cheap fix to bring the height back up.

mvusse Posted May 22, 2014 Share Posted May 22, 2014 The D44 came with the MT package, but it also came with the towing package and could be optioned separately as a "heavy duty rear axle". Link to comment Share on other sites More sharing options...
8valvehero Posted May 22, 2014 Author Share Posted May 22, 2014 I guess a vin check is in order. But while we wait for that, riddle me this: What separates a MT from the towing package w heavy duty rear axle? Is there a way to ID the extra springs as OEM?

dave92cherokee Posted May 22, 2014 Share Posted May 22, 2014 You might have metric ton springs with the extra helpers bolted on to them, just took a closer look at the pic of the new springs and zoomed in on it and you've got a 4/1 pack which I believe has always been denoted as a metric ton pack. If it was me I would take off the overload springs that someone previously bolted on as they're only a bandaid on a broken leg. If the springs are sagged and can't hold as much weight then you'd be better off ordering new MT spring packs from somewhere like general spring or hell creek.

8valvehero Posted May 22, 2014 Author Share Posted May 22, 2014 The rear end is a little high, so maybe that's why. I'll get out tothe JY soon and check the vin, then we'll know Link to comment Share on other sites More sharing options...

For the AMC years, the D35 had 10x1.75" rear drums. Chrysler changed to 9x2.5". I don't believe there was ever a 9x1.75" rear brake used under the MJ or the XJ.

Incommando Posted May 22, 2014 Share Posted May 22, 2014 My '88 SWB also had the towing package and D44 without the metric ton group. Nice score in that the axle was even from a LWB so you didn't have to screw with the shock mounts. Link to comment Share on other sites More sharing options...
mvusse Posted May 23, 2014 Share Posted May 23, 2014 Axles from lwb and swb are identical. The shock mounts are on the leaf spring u bolt plates and between lwb and swb they are simply swapped left to right and right to left. Link to comment Share on other sites More sharing options...
8valvehero Posted June 3, 2014 Author Share Posted June 3, 2014 Ok so I finally got a chance to go over to the junkyard and gather some info. Here's what the VIN search reveals: "VIN : 1JTML6513JT190486 Country : United States Manufacturer : Jeep Corporation Vehicle Type : Truck Engine : 1989, 6 Cyl. 4.2 Liter / 4.0L I-6 Cyl. MPI Powertrain : 5-speed manual, floor gear shift, part time 4 W/D Line (Body Type) : Jeep Comanche, 4-W/D Pickup, 7.0' bed, 120" wheel base Model and Gross Vehicle Weight : 4001#-5000# : Wrangler Base / Cherokee Base / Comanche Base [1815/2268 Kg] Check Digit : 3 Year : 1988 Plant Location : Toledo, Ohio, USA Sequential Serial Number : 190486 Check Digit Test : VIN valide" That's that. "1815/2268 Kq" means the donor is not a Metric Ton. So what I'm wondering, is what separates the MT from the 'towing package' with big brakes and d44? Is it just the presence of the OEM helper springs and some badges? Also here's a pic of it. I did want the bed, but a dent turned up in the side since I'd seen it last. Still getting the doors and front axle though... Link to comment Share on other sites More sharing options...

HOrnbrod Posted June 3, 2014 Share Posted June 3, 2014 They were optional and called "low profile" mirrors, although I have no idea why. Unless they were placed the lower than the other types....... Link to comment Share on other sites More sharing options...
