Jeep Driver Posted February 20, 2014 Share Posted February 20, 2014 There is a thread ongoing regarding the D44 conversion which has me questioning the D35 conversion. What I have found, past and present, when doing a search is C-clip to C-clip conversion........straight forward enough. There are several ZJs at the PnP with D35 discs. Last week I inquired as to the cost of backing plate, e-cables, rotors, calipers................$80 But now I'm thinking about the thickness differences in the two plates, will this be a problem with a non C-clip axle? Thanks Yeah I know, I know........but I have decided that the D35 stays. Link to comment Share on other sites More sharing options...
Rockfrog Posted February 20, 2014 Share Posted February 20, 2014 Doing an early non-clip D35 will be similar to a D44 ... you need to maintain preload on the bearing. I'm getting around that by just swapping in a ZJ D35 complete. Link to comment Share on other sites More sharing options...
HOrnbrod Posted February 20, 2014 Share Posted February 20, 2014 ^^ This. The non c-clip D35 uses the same preload spacers as the D44. The axle flange holes and spacing are also the same. This is not the case in a c-clip D35. Rusty pic example: Link to comment Share on other sites More sharing options...
JeepcoMJ Posted February 20, 2014 Share Posted February 20, 2014 Axle tube thickness should be the same on d35, so you shouldn't need to open up the center hole on dizc backing plates. Identical other than that to a d44 swap Link to comment Share on other sites More sharing options...
Jeep Driver Posted February 21, 2014 Author Share Posted February 21, 2014 Thank you. So, let me make certain I understand..... If the backing plate of the disc set is thinner, the bearing will have too much pressure/load at the race.....? To seat it correctly shims are used.....? Why can not just get some shim stock and make my own shims? When setting up a non-c from scratch how do you determine the pre-load? Link to comment Share on other sites More sharing options...
HOrnbrod Posted February 21, 2014 Share Posted February 21, 2014 The preload spacer is required because the ZJ backing plate is not the same thickness as the drum brake backing plate. So to make up the difference and keep the axle seals (not bearings) preload correct the spacers are required. Otherwise it's leak city. The dimensions for my D44 (your non-c-clip D35 should be the same) were .225" thick x by 2.90" OD x 2.45 ID. But you should do your own measurements to be certain. Your favorite local machine shop can fab them up or you can get them from Teraflex for about $6/ea. Link to comment Share on other sites More sharing options...
Jeep Driver Posted February 21, 2014 Author Share Posted February 21, 2014 Now I see, thank you. So the bearing still needs to come off? And I assume you drill new holes for the mounting bolts? Link to comment Share on other sites More sharing options...
HOrnbrod Posted February 21, 2014 Share Posted February 21, 2014 Yes, you'll need to pull the axle and bearing. If you send me an email address I can sent the Teraflex Ford Explorer disk brake installation manual for older Jeeps - it's not on their website anymore. The procedure will be the same as converting to ZJ disk brakes. Link to comment Share on other sites More sharing options...
benjy_26 Posted February 23, 2014 Share Posted February 23, 2014 I don't know jack about this, but coul maybe a disc brake set up from a D44A equipped ZJ make the conversion smoother? Link to comment Share on other sites More sharing options...
randomguy310 Posted February 23, 2014 Share Posted February 23, 2014 build one at the junkyard.. and buy the whole non c clip d35 for a xj with disc brakes for about 150 plus core usually, just a thought, no better lace to make sure you have all the right parts...

JeepcoMJ Posted February 23, 2014 Share Posted February 23, 2014 No on the zj 44. Same mounts as d35 Link to comment Share on other sites More sharing options...
jimoshel Posted February 24, 2014 Share Posted February 24, 2014 I'm just wondering if it wouldn't be easier to just swap the whole axle assembly instead of messing with just the brake stuff. Cut and reweld the spring mounts and you're done. Link to comment Share on other sites More sharing options...
JeepcoMJ Posted February 24, 2014 Share Posted February 24, 2014 Not everyone has skill to weld perches. Actually, 90% of the forum has not got the tools or experience to get penetration. With a 110v welder, perches cannot be done well enough to pass a weld test unless preheated Link to comment Share on other sites More sharing options...

I wish it were that easy. I can pick up 8.25s all day long here......$150 and a pile to choose from, literally. But all from 4.0s and I'd rather not regear, but is likely what I will do.
