jeepmjga Posted July 17, 2021 Share Posted July 17, 2021 Maybe the gurus can lend a helping hand here as I'm at my wits end. I'm working on replacing the joints both sides and I am on ball joint set #3 now and still haven't found a replacement that works. 706944x does not fit and the other two napa and rock auto sets I got did not fit either. The only numbers I could find on the current joints are Upper - DW057389533 and Lower - OEJN 040110. Pics are attached. Both sets of spicer joints I ordered have the smooth surface and not the grooved. The napa set I got had the grooved surface but still didn't fit either. I guess the spicer joints must be like .001" smaller than what is currently in there. Any one got any part numbers or any idea why all these old joints are bigger than everything else thats listed for the D30? Thanks for any help. Edit: I'm seeing the MOOG part numbers 3134 and 3137, just wondering if they are the same diameter as the spicer ones? Anyone got any input?

eaglescout526 Posted July 17, 2021 Share Posted July 17, 2021 Need OEM part numbers? Usually that helps cross reference stuff. Link to comment Share on other sites More sharing options...

It looks like the PO put in knurled ball joints and the spicers are smooth which would explain the small difference in size. It looks like the MOOG joints are knurled also. I've heard of using a punch to stipple the hole in the Inner C and basically create a smaller hole but would obviously use that as a last resort.

JMO413 Posted July 18, 2021 Share Posted July 18, 2021 The Moog problem solver ball joints are knurled. I have put the sets in and they were all knurled. Link to comment Share on other sites More sharing options...
eaglescout526 Posted July 18, 2021 Share Posted July 18, 2021 Is your front D30 original or newer? Link to comment Share on other sites More sharing options...
ghetdjc320 Posted July 18, 2021 Share Posted July 18, 2021 706944X is what I’ve always used. And that was after pressing out some Moog knurled ones. What exactly doesn’t fit? Link to comment Share on other sites More sharing options...

As far as I know its original, but I didnt get much info on the PO since I bought it from a guy who had it as a shop project. 11 hours ago, ghetdjc320 said: 706944X is what I’ve always used. And that was after pressing out some Moog knurled ones. What exactly doesn’t fit? The joints just drop right in to the hole without any resistance. Like they are about .001" too small. I ordered some moog ones, gonna see if those fit, if not then back to the drawing board I guess. Link to comment Share on other sites More sharing options...
eaglescout526 Posted July 18, 2021 Share Posted July 18, 2021 83500202AB-So this is a kit for both upper and lower joints. No separate part numbers. Link to comment Share on other sites More sharing options...

Awesome thanks if these moog joints don't work that will help. Adding info to the library anyway. Link to comment Share on other sites More sharing options...
ghetdjc320 Posted July 19, 2021 Share Posted July 19, 2021 Sounds like maybe someone botched the ball joint install at some point in time on this axle and messed up the holes Link to comment Share on other sites More sharing options...

If they are still too small I'm going to try stippling the inside of the holes with a punch. Basically another kind of knurling I guess. Would prefer not to replace the housing but there are plenty at the junk yard around here. Link to comment Share on other sites More sharing options...

Of course, the person who trashed the ball joint bores also splayed one of the “C’s” that the knuckle attaches to, so it was new axle housing time anyhow😠 Link to comment Share on other sites More sharing options...
ghetdjc320 Posted July 20, 2021 Share Posted July 20, 2021 I believe a lot of these previous owners lacked the proper tool to install the ball joints correctly. It’s a pricey tool but worth it. Link to comment Share on other sites More sharing options...
howeitsdone Posted July 20, 2021 Share Posted July 20, 2021 So do the MK3137T and MK3134T not work? I just ordered the MOOG replacements and they'll be here Friday for an install. Link to comment Share on other sites More sharing options...

I love Moog parts but on these axles you want the Dana/Spicer 706944X. They have consistently outlasted the moog/precision joints 2:1 with big tires and/or lots of wheeling Link to comment Share on other sites More sharing options...
jeepmjga Posted July 20, 2021 Author Share Posted July 20, 2021 Well they ended up working, they were a little larger diameter than the ones that came out but I still took a punch and made a couple passes through each hole. They pressed in nice and tight after that and it finally steers like it should. I ended up using the 3134T for the upper and 3161T for the bottom. Guess I should have just replaced the power steering hoses too when I put in the new gear and pump though because the pressure line somehow got a tiny pinhole in it After that should be good to go! Thanks again for all the replies. Link to comment Share on other sites More sharing options...

Salvagedcircuit Posted June 14, 2023 Share Posted June 14, 2023 I have a similar problem with my ball joints, but mine are still intact and work great - just the passenger side top ball bearing is missing a grease fitting. I looked at the top of the ball joint and while there's a hole for a fitting, there were no signs of threads in fitting itself. There are slight signs of marks, not nothing substantial. There was no sheared or cut off fitting. The ball joint has not failed at all, I just like to grease ball joints and not rely on finger crossing. I'm debating replacing the entire ball joint, but it would be a lot easier if I knew what size fitting the ball joints use. Rock auto says the Moog K100056 is the correct ball joint. I called Moog and they said the fitting is likely a 1/4-28 zerk self tapping grease fitting Does anyone else remember if the fitting they used on their ball joints was a zerk self tapping fitting? I'm hoping the previous owner just forgot to install it. Thanks! Link to comment Share on other sites More sharing options...
