I can't grease the rear spring bushings. One zerk is gone, looks like it was yanked out or smashed in. The other one is a fat zerk I can't get my grease gun to attach to. These spring bushing zerks look pressed in, so I can't screw in a new zerk. Sections S-4, S-5 of the Service Manual discuss removing/installing the spring and S-6 for installing the bushings. I was hoping to avoid dropping the axle, but it looks like I'm gonna have to do it. Are there any tips or tricks I should know about? The driver side, rear spring bushing. Shackle bushing passenger rear. Edited by jeepdidwhat - 14 Sep. 2021 at 8:19am |

Yes many of the later threaded bushings for the “U” type shackles have zerks that were a press fit.
You don’t need to drop the complete axle; only remove the offending threaded bushing. Possibly could press fit in a new zerk or try tapping the threaded bushing using an 1/8” NPT tap. The hex head bushing showing the grooves around the outside of head is LH threaded. Edited by oldtime - 14 Sep. 2021 at 8:36am |

Here's a new one for me......
I've only known threaded zerks. It may help to google this and see what's already posted as far as videos/articles on zerks. I see there's a tool (similar to a tire valve stem tool) to help with removing/replacing zerks. This website seems to describe non-threaded applications: To add to my lack of enlightenment, that second image looks like it's too far in to accept a grease gun nozzle - so it may also need to be removed.

The "fat" one has the end broken off.
Just carefully drill them out and press a couple new ones in. The press in ones I've seen look threaded but the "threads" aren't spiral, they're rings that wedge the zerk in place. PS Grainger has them with pics

Wow, I did not know about press fit grease fittings. The hole is about 5/16 inch diameter and I see 5/16 inch fittings. I'll order some new fittings and an installation tool. I'll also try to drill the old fitting out carefully and slowly and see what happens. I am a little concerned about metal scrapings falling inside the joint. |

The flutes on the drill bit should pull them out. Drill a little and then wipe the bit clean.
Get your grease fittings first, then select a bit just slightly smaller.

Press fit zerks can be driven out from the inside via a punch.

Oldtime is right.
Just wrench the bushing out, put it in a vice, drive out the grease fitting with a drift punch, and drive in a new one.

You guys are so ingenious with your ideas. So much ingenuity, so much perseverance. In this instance I’d say invest $20 in all new spring shackle bushings. It’s kind of a throw away maintenance item.

I was trying to avoid the extra work of unloading/removing the spring to change the bushing out. I was looking for a possible quick fix so I can keep driving. Every time I take something apart, mission creep occurs and the jeep is disabled for a while. I'm already planning my order of Ubolts, spring bolt pivot, and spring shackles/bushings. Maybe even some bronze replacement bushings for the spring bolts just in case these are worn. |

Drilling out was so close to working. The existing hole is 5/16" and my 1/4" bit didn't get it all. I have a ring of metal that will rotate when I tap with a punch, but can't get it to move out of the hole. I think I'll have do this the hard way. |

Well, I got the new C shackles and they are twisted (legs not parallel). I saw a few posts from others with the same problem. I don't have a press, so I can't bend it back. I expected a complication. |

The “U” type shackle is supposed to have a slight twist …….
Why don’t you have your old ones for comparison ? Don’t scrap out your old clips (“u”bolts). If rusted Remove the nuts after heating them to dull red. Not picking on you but you must either become a knowledgeable Jeep mechanic or you will be working for ommix for life.
