DJM/78 Posted January 9, 2010 Share Posted January 9, 2010 I'm wanting to know as well . Could you buy the parts new , from say NAPA or OEM ? Are the parts a direct swap ? What should we look out for ? I am doing this , or trying anyway to my 89" Dana 44 . Link to comment Share on other sites More sharing options...
mvusse Posted January 9, 2010 Share Posted January 9, 2010 ZJ rear disc brakes are a direct bolt on for a D35 or D44. If you enlarge the 2 3/4" center hole to 3", they will bolt to an 8.25" as well (that's what I did). Disc brakes need more pressure than drum, so you want to replumb the rear lines using the ZJ proportioning valve as well. The brackets and backing plates must come from a stealership or junk yard, everything else is available from parts stores. Link to comment Share on other sites More sharing options...
dasbulliwagen Posted January 9, 2010 Share Posted January 9, 2010 Wasnt there someone talking about getting rear discs for these froma crown vic? Id like to know more about that too if it is what it is. Link to comment Share on other sites More sharing options...
johnnyc Posted January 9, 2010 Share Posted January 9, 2010 IMO, the Explorer conversion is the easiest to obtain. There are plenty of 4-disc Explorers in the junkyards. Here's my Explorer rear disc equipped Dana 44. Link to comment Share on other sites More sharing options...
LEAD_NOT_FOLLOW Posted January 9, 2010 Share Posted January 9, 2010 ZJ rear disc brakes are a direct bolt on for a D35 or D44. If you enlarge the 2 3/4" center hole to 3", they will bolt to an 8.25" as well (that's what I did). They are not a direct bolt on for a D44. You need to make a spacer (axle retainer) as the ZJ one is not thick enough. You'll also need to enlarge the center hole of the backing plate a bit as well for the D44. As far as bolt-on kits available on the market; Crown as well as TeraFlex both make kits now that include everything needed and that will simply just bolt-on.

DJM/78 Posted January 9, 2010 Share Posted January 9, 2010 Does that still apply to the 89" XJ dana 44 ? I am assuming they are pretty much the same . :dunno: Thanks ! :dunce: in training ! Link to comment Share on other sites More sharing options...
500 MJ Posted January 9, 2010 Share Posted January 9, 2010 I've done the ZJ disc conversion on my '87 XJ D44. I used the same procedure as is outlined at http://www.madxj.com There is no direct link to the page but it is under the Technical side tab and then you need to scroll down to the Brakes headliner. The writeup on how to do it is the first one. Pretty simple to do. I had to weld some little home-made tabs on my e-brake cables to get them to work. As far as the axle seal spacers go I was able to make mine in our shop on the drill press with some hole saws and some 1/4" steel - took forever to cut them with the hole saws though... Here are some of the pics I've got of 'em: Here are the tabs I welded to the cables. Hope that helps. Does that still apply to the 89" XJ dana 44 ? I am assuming they are pretty much the same . :dunno: Thanks ! :dunce: in training ! All years ('87-'89) XJ D44 were the same. Link to comment Share on other sites More sharing options...

Pile29 Posted October 28, 2018 Share Posted October 28, 2018 This all seems to be for 88's. Would the swap be the same for a 91 2wd comanche? I loathe drum brakes with a deep and fiery passion and theres a parts store here in Victoria that seems to be able to get any part I would ever need for relatively cheap. The wreckers here suck and are way out of the city. 1991 Eliminator4L 6CYL2WDbuilt October 1990 Link to comment Share on other sites More sharing options...
