No grease E-Z lubes shackles

Was wondering if someone could let me know why I cannot get any grease in the Last shackle. I just went around and greased all my shackles but 1 it will not let any grease in, I took the grease zerk out and no obstruction also no obstruction in the wet bolt I ran a piece of 14 gauge wire in the bolt it went in no problem. Is it possible the shackles are over tightened and cant let any grease out? I am at a loss here. I do have the Dexter E-Z flex equalization system with the E-Z lube heavy duty axles with bronze bushings in the shackles. Thanks for any help!Click image for larger version

I had that same problem once when adding grease to my ez-flex shackle. Just one of them. I figured the shackle bolt,was,probably,jammed tight against the bushing so I raised the trailer up on that side with my level up system to take some weight/pressure off the shackle bolt and it allowed me to grease it. Good luck..

A lot of times it's best to grease items like this while unloaded. This allows grease to flow to all the bearing surfaces more easily. In this case I'm guessing that the load was carried in the same place as the outlet of the grease passages. Even if it wasn't and grease flowed grease would only flow to spaces not pinched off by load. Since these pins aren't rotating like a journal or roller bearing grease tends to stay where it is and doesn't re-distribute itself as well.

That makes sense I will grease it that way. Thank you

The bolts are required to be installed with the grease hole facing 9:00 or 3:00. if the bolts were installed with the hole facing up or down, you will have trouble getting grease in.


This is for the Morryde system but will be similar to yours.

Those bolts are supposed to be installed with the grease hole in the bolt shank to be facing for or aft. If it is facing down the pressure of the bushing on the bolt will prevent the easy flow of grease.

Loosen the nut, rotate the bolt 90 degrees and tighten the nut again. I bet your problems will be over. well...........this problem at least

A bit of advice here ... don't simply loosen the nut and CRANK the bolt to the proper position. Leave the nut on the last few threads and tap the bolt out of the mount enough to clear the serrations under the head, rotate the bolt, then re-seat the bolt in the mount. The serrations are on the bolts for a reason.

Yea, I learned that from babockís post. I just had my ez-flex suspension replaced. I wonder if the mechanic set the wet bolts correctly? I will have to ask him. Now on to my next problem..lol..

Yes that is what I did you had to loosen the nut then tap the bolt out enough to turn it in the right position. Thank for the info.

Question, if I only tap the bolt out about 1/4 inch how do I know where the hole in the wet bolt is located if I can’t see it?

Seems to me I would have to tap the wet bolt out far enough to see the grease holes?

When I tapped mine out a 1/4 inch I noticed my bolt had same letters on 1 spot so I just looked at how my other bolts were with the letters, mine were positioned at 6:00 and 12:00 so I turned it to the same clock position and it worked for me. Maybe that might work for you.
