theksmith 4,019 Posted May 2, 2016 Well, the "new" 247J is in, it's just a matter of getting a new front driveshaft. No picture sadly, since my driveway is still pretty well soaked in dirt and TC fluids, I can't get down there unless I expect to scrub up afterwards. Almost back on the road! yay! did you get it mounted by yourself? when i did the 242 rebuild, i had a hell of a time trying to lift it up and line up the splines and get it on the studs - ended up having ScottL come do the lifting and me do the aligning Share this post Link to post Share on other sites
BigTuna117 33 Posted May 3, 2016 yay! did you get it mounted by yourself? when i did the 242 rebuild, i had a hell of a time trying to lift it up and line up the splines and get it on the studs - ended up having ScottL come do the lifting and me do the aligning Yeah! We borrowed a floor jack and propped the transfer case on that. from there, it took 3 hands to maneuver it into place and one hand to align the splines. once that part was done it was all downhill from there. In other news, I found out today that the "exhaust manifold rattle"that I've been trying to get at for the last few months isn't actually a manifold rattle. The heat shield around the manifold has broken itself free on once side, so at least it's not as critical as a manifold leak. I'll still try to fix it of course.

aloysius80 0 Posted May 5, 2016 if you have still got the old 247 you could rip the imput shaft out to swap into a 242j if you can get one cheaper than a 242hd. only got to change that (maybe the bearing depending on year) and change the shifter linkage. works so much better than the 247.

BigTuna117 33 Posted May 5, 2016 if you have still got the old 247 you could rip the input shaft out to swap into a 242j if you can get one cheaper than a 242hd. only got to change that (maybe the bearing depending on year) and change the shifter linkage. works so much better than the 247. The funny thing about this is: This was actually going to be my next project. A good friend of mine (UnderlyVerbose on here) was gonna both sell me a 242, and teach me how to rebuild it myself. Will still be doing this, but the added expense of replacing the front yoke & drive shaft means that it'll have to be bumped back a few months. I actually spent more obtaining a front driveshaft than I did on the "Donor" 247J transfer case and all the fluids- another friend of mine had one lying around, and sold it to me for $100 given the crappy situation.

aloysius80 0 Posted May 10, 2016 The 247 in our wj was not happy. Sounded like the chain was slipping on steep climbs and drive to the front wheels seamed to come and go. Got the 242 from a high millage xj only cost was time and rtv sealant. If your front shaft is different you should be able to swap the yolks over to suit too. If you feel like climbing back under there again. I know ours now climbs so much easier than it did with either of the 247s that i had in it. Hope this helps.

BigTuna117 33 Posted May 10, 2016 Soo Pretty, Soo Shiny! Wanted to show off the new driveshaft. it features greasable EVERYTHING (including the ball joint in the double cardan end), and a full length spline in the slip joint. I'm pretty impressed. It's a beefy propshaft! So, the Jeep is driveable again. I have an acceleration clunk and driving wobble, I think the bushings in the front lower control arms are finally toast. So, I suppose that'll be the next project! Share this post Link to post Share on other sites

In fact, this recent... breakage only delayed my hunt to get it done. If my 247 hadn't gotten... explodey, I would've probably had the swap completed by now. It certainly is a great upgrade.

BigTuna117 33 Posted June 6, 2016 Well, the shenanigans continue! On the hottest recorded weekend of 2016, I am without A/C... again. The orifice tube (essentially a $2 plastic-and-metal screen which DaimlerChrysler decided to fully integrate into the liquid line) clogged up, and overpressured the compressor. Blew one of the internal seals to smithereens. So now I am waiting for a package to arrive with a new liquid line, High pressure line (because it's the last original line, might as well replace it while I'm replacing parts), and a new compressor from Denso. Hopefully they arrive soon so I can get it fixed soon. It's brutal driving around with no A/C in this heat! Share this post Link to post Share on other sites
theksmith 4,019 Posted June 6, 2016 A/C issues in the heat sucks! where did you get the shiny driveshaft from? Share this post Link to post Share on other sites
BigTuna117 33 Posted June 7, 2016 It's assembled by A-1 Driveshaft in Wisconsin. Woulda done Carolina driveline or Tom Woods, but that had it pre-made in stock and I needed it asap! All in all it's a very beefy driveshaft, it probably weighs a whole 5-10 pounds heavier than the previous shaft. The fact that everything is greasable (including the ball joint inside the double cardan) is pretty handy too! Share this post Link to post Share on other sites
